When there is concern about developmental delay in a child birth control pills jolessa generic 15mcg mircette fast delivery, a developmental quotient should be calculated birth control online buy mircette without a prescription. Typical development is a developmental quotient greater than 70% birth control 3 day period cheap mircette online visa, and atypical development is a developmental quotient less than 70% birth control for women 70s outfit buy mircette 15mcg online. Toddlers and young children with atypical development are at risk for lifelong developmental problems birth control 21 day pack mircette 15 mcg without prescription. The term global development delay is used if a child younger than 5 to 6 years of age has a developmental quotient less than 70% in two or more domains necon birth control 0535 safe mircette 15mcg. Children with global developmental delay should receive a thorough medical evaluation to try to determine the cause of the delay and begin management for their developmental disabilities. Developmental delay is common and one of the most frequent presenting complaints to a pediatric neurology clinic; therefore, neurologists should have a systematic approach to the child with developmental delay. This article begins with a brief discussion of child development concepts related to typical and atypical development. Although typical child development follows a relatively consistent sequence, it is not linear. For example, motor development in the first year of life proceeds relatively rapidly. Babies typically mature from being completely immobile to walking in just over 12 months, but then motor development progresses less dramatically during the second year of life. On average, most children achieve each developmental milestone within a defined and narrow age range (Table 8. The social history should probe for environmental factors that can affect development, including physical or other forms of abuse, neglect, psychosocial deprivation, family illness, impaired personalities in family members, sociocultural stressors, and the economic status of the family. The pertinent aspects of the family history include developmental disabilities, special education services or failure to graduate from school, neurodegenerative disorders, multiple miscarriages or early postnatal death, ethnicity, and consanguinity. If a specific genetic syndrome is suspected, the clinician should inquire about the presence in other family members of medical problems associated with that syndrome. For example, if the child has the features of fragile X syndrome, the family history should include questions about maternal premature ovarian failure, parkinsonism or ataxia of unknown etiology in the maternal grandfather, and intellectual disability or learning problems in an X-linked pattern. In the mental status portion of the examination, the clinician should note the interactions the child has with his or her caregivers and the clinician. Abnormal behaviors such as impaired eye contact, limited or absent social reciprocity, restricted or repetitive behaviors, and communication impairment may indicate that the child has an autism spectrum disorder, and the child should be referred to a psychologist for assessment or confirmation of this condition. Other abnormal behaviors such as hyperactivity, impulsivity, and inattention, as well as suboptimal parenting skills, may also be noted during these observations. A complete general physical and neurological examination should be performed to the extent the child will allow. The general examination should include but not be limited to an evaluation for dysmorphic features: abnormalities of the eyes (Table 8. The neurological examination should include signs of impairment in extraocular movements; hypertonia or hypotonia; focal or generalized weakness; abnormal posture or movements; abnormal or asymmetrical tendon reflexes; ataxia, incoordination or other signs of cerebellar dysfunction; and gait abnormalities (see Table 8. This is pertinent because many chromosomal anomalies and other genetic disorders that cause global developmental delay and intellectual disability are associated with failure to thrive or short stature, large stature, microcephaly, and macrocephaly. DiagnosticTesting Diagnostic testing in an individual with global developmental delay should be offered to the family, because the testing may provide an etiology for the developmental delays, could alert the physician and family to comorbid conditions the child is at risk for developing, can help provide recurrence information to the family, and may rarely lead to specific medical treatments or therapeutic interventions. Genetic Testing Based on the developmental history obtained, a diagnosis of global developmental delay can be made. In addition, the clinician should attempt to identify an underlying etiology for the delay. Occasionally, the history and examination suggest a specific recognizable genetic condition or other cause. For example, a girl with a history of global developmental delay who has acquired microcephaly, epilepsy, and midline hand wringing should be tested for Rett syndrome. Frequently, however, the underlying cause is unknown despite the acquisition of a comprehensive history and physical examination. This is also the first-line test for individuals with nonspecific intellectual disability, an autism spectrum disorder, and multiple congenital anomalies (Miller et al. Though this test has a relatively high diagnostic yield, it will typically not detect inversions and other balanced rearrangements. Consequently, if the microarray is within normal limits, a follow-up highresolution karyotype can be considered. Therefore, every child with nonspecific global developmental delay regardless of gender should also have fragile-X testing performed. Physical examination findings that should increase the suspicion of a metabolic disease include microcephaly, macrocephaly, growth failure, unusual odor, coarse facial features, unusual birthmarks, abnormal hair, hypotonia, dystonia, and focal weakness. Urine studies to consider include organic acid analysis, purine and pyrimidine metabolites, and creatine metabolites (in boys). However, many of these changes are nonspecific and do not lead to the diagnosis of a specific etiology for the developmental delay. In children with global developmental delay, it is important to confirm that the universal newborn screening test was normal at birth. Nonetheless, the diagnostic yield of biochemical testing in a child with nonspecific global developmental delay is quite low (<1%) (Moeschler and Shevell, 2006). However, these studies are rarely indicated until the mentioned routine studies have been completed. As with any situation in which the physician discloses difficult news, this must be done gently but clearly. The clinician should be prepared to respond to a full range of emotions including doubt, denial, sorrow, and anger. Furthermore, the family will usually need time to process the information that their child has or is at risk for having lifelong developmental problems. Therefore, a follow-up appointment should be scheduled to review the diagnosis and address additional questions or concerns the family may have. In addition, any comorbid conditions should be treated, or the clinician should refer the patient to the appropriate subspecialist who can provide treatment for the comorbid condition. The clinician can also help facilitate social, community, or educational supports for the family. These may include family support groups, national parent organizations, and other resources in the community for families of children with developmental disabilities. One of the most important aspects of the management of a child with global developmental delay is ensuring that the child receives early and appropriate therapeutic and educational interventions. Children younger than 3 years of age with developmental delays can be enrolled in early intervention programs. Their assessment is summarized in a report called the Individualized Family Service Plan; this plan serves as the basis for provision of therapeutic services. Children who are older than 3 years of age receive services through the special education program within the local school district. These services are usually provided by a multidisciplinary team of therapists as well as a psychologist. Federal law mandates that children receive the special services they need in the least restrictive environment possible. Therefore, many children with developmental disabilities are now educated in the regular ("mainstream") classroom with an aide instead of being placed in a separate classroom. However, some children with more significant intellectual or behavioral problems may require placement in a special education classroom for part or all of the day. In an otherwise healthy individual with developmental delay, the life expectancy is normal. Children with significantly impaired mobility or other neurological impairments may have a shortened life expectancy. Though some toddlers and young children with developmental delay may "catch up" and ultimately have typical development, global developmental delay is associated with an increased risk for having a developmental disability-a lifelong and chronic condition due to mental and/or physical impairments that impacts major life activities such as language function, learning, mobility, self-help, and independent living. Several types of developmental disabilities exist, including cerebral palsy, learning disabilities like dyslexia, intellectual disability, autism spectrum disorders, attention deficit-hyperactivity disorder, hearing impairment, and vision impairment. These developmental disabilities are predominantly impairments in a specific subset of the developmental domains. For example, cerebral palsy is primarily an impairment of gross and fine motor skills; intellectual disability is primarily an impairment of language, problem-solving, and social-adaptive abilities; and autism spectrum disorders are primarily disorders of social-adaptive behaviors with or without language and communication impairments. Approximately 16% to 18% of children have a developmental disability that includes behavior problems, and 1% to 3% of the population has an intellectual disability. Toddlers or preschool children who are diagnosed with global developmental delay are at highest risk for being diagnosed with intellectual disability at an older age, especially as the developmental quotient worsens. Males are more likely to be affected than females; occurrence rates are 1: 4000 males and only 1: 6000 females. In general, the diagnosis of intellectual disability is not made in a toddler or preschool child unless they have been diagnosed with a specific genetic condition associated with intellectual disability. In the absence of a specific genetic diagnosis, the diagnosis of intellectual disability in most children is made once they are able to complete formal psychology testing at approximately 5 years of age. In our practice, when the developmental delays of a child younger than four are very severe, we will occasionally tell the family that the child will likely have intellectual disability. In these situations, we may share this concern even if the child does not have a formal diagnosis of a genetic syndrome or before the child is old enough to complete formal psychology testing. Children with severe developmental delays may in fact be too impaired to perform formal psychology testing. In young children with mild developmental delay, it is not prudent to predict a developmental outcome with certainty. A recurrence risk can only be provided with certainty if a specific etiology has been confirmed. Despite extensive genetic testing and other evaluations, the majority of children with developmental delays will not be diagnosed with a specific named genetic condition or other etiology for the delays. Though each case is unique, the most prudent approach is to remind the family that 1% to 3% of the population has intellectual disability, and their risk for having another child with global developmental delay and subsequent intellectual disability is greater than the population risk. It is helpful to double frame the risk by also stating that it is more likely that they would have an unaffected child than an affected child. In addition, a regressive disease may begin to manifest itself as the development of a new neurological problem, such as a new-onset seizure disorder or movement disorder, development of a different type of seizure in a child with epilepsy, vision impairment, behavior problems, and dementia or cognitive decline. In a child with neurological regression, a thorough neurological history and examination is warranted. The history should focus on any modifiable factors that could contribute to neurological decline, including worsening of another medical problem, recent modification to an existing medication regimen or initiation of a new medication, recovery from a prolonged acute illness or surgery, or a psychosocial stressor. All children with neurological decline should receive an extensive physical examination, with attention to those aspects of the examination that could provide clues to an underlying neurodegenerative disease (see Table 8. A pediatric ophthalmologist should also examine the patient for ocular stigmata of a neurodegenerative disease (see Table 8. Categories of genetic diseases that should be considered include aminoacidopathies, organic acidurias, fatty acid oxidation defects, glycogen storage diseases, mitochondrial cytopathies, lysosomal storage diseases, neuronal ceroid lipofuscinoses, peroxisomal disorders, neurotransmitter synthesis disorders, spinal muscular atrophy syndromes, creatine synthesis disorders, congenital disorders of glycosylation, metal metabolism disorders (Menkes, Wilson, pantothenate kinase-associated neurodegeneration), and purine and pyrimidines disorders. Alternatively, if the presentation is nonspecific and not pathognomonic for one of the above conditions, it may be most prudent and productive to perform whole exome sequencing as a first-line test. It is now very rare that more invasive procedures are warranted, including biopsies of the skin, muscle, liver, nerve, bone marrow, or conjunctiva. Many reasons exist for aggressively pursuing a diagnosis of an underlying neurodegenerative disease. However, early diagnosis can reverse the neurological impairment or prevent future morbidity is some conditions such as Wilson disease, homocystinuria, and glutaric aciduria type I. Furthermore, a correct diagnosis can help the clinician provide better information about prognosis and life expectancy. Recurrence risk information and prenatal diagnosis may also be offered to families. For those conditions that are progressive and life limiting, the clinician should collaborate with a pediatric palliative care team to discuss end-of-life goals of care with the family. Identifying infants and young children with developmental disorders in the medical home: an algorithm for developmental surveillance and screening. Clinical genetic evaluation of the child with mental retardation or developmental delays. Report of the Quality Standards Subcommittee of the American Academy of Neurology and the Practice Committee of the Child Neurology Society. In the past 3 decades, a number of significant advances have been made in our understanding of the neuroanatomy, neurophysiology, and chemoarchitecture of the frontosubcortical circuits. An increasingly broad spectrum of neuropsychiatric phenomenology is now being interpreted in the context of dysfunction in this region. A brief overview of the frontosubcortical circuits and their signature behavioral syndromes is offered as a strategy to better understand the behavior and personality changes that accompany neurological conditions. Alexander and colleagues described five discrete parallel circuits linking regions of the frontal cortex to the striatum, the globus pallidus and substantia nigra, and the thalamus (Alexander, DeLong and Strick, 1996). In general, the direct pathway facilitates the flow of information, and the indirect pathway inhibits it. Five frontosubcortical circuits were initially described as motor, oculomotor, dorsolateral prefrontal, lateral orbitofrontal, and anterior cingulate gyrus. Efforts to link functional domains to this brain circuitry have been developed and revised over the past few decades. Disruption of dorsolateral prefrontal, lateral orbitofrontal, and anterior cingulate gyrus circuits is associated with behavioral and personality disruptions. Specific behavioral syndromes have been attributed to dysfunction in these circuits (Box 9. Finally, the anterior cingulate gyrus circuit is associated with decreased motivation, apathy, decreased speech, and akinesia. Although these models may be heuristic in developing function-structure hypotheses, it is unlikely that any current model is sufficient to explain the complex interface between behavior and brain circuitry. Additionally, the role of the amygdala in behavior and personality disturbances is an area of increased interest and research.

For those women with conotruncal abnormalities (tetralogy or pulmonary atresia) birth control pills news mircette 15 mcg for sale, screening for 22q11 deletion is recommended birth control for 18 year olds discount mircette express, because this has autosomal dominant transmission birth control pills 28 days purchase cheapest mircette, and the offspring have a 50% chance of inheriting the genetic defect birth control joint pain buy generic mircette line. An atrial communication poses the added potential risk of a stroke from a paradoxical embolus birth control meme discount 15 mcg mircette fast delivery, and meticulous attention should be paid to the possibility of maternal deep vein thrombosis birth control pills mix up order mircette 15 mcg free shipping. Atrial arrhythmias may not be well tolerated in the pregnant woman with this anomaly, and both atrial fibrillation and reentry tachycardia are common. Accessory bypass tracts causing preexcitation may precipitate rapid tachycardia, which add to the burden of a poorly functioning right ventricle. After successful surgical repair or replacement of the tricuspid valve, pregnancy may be well tolerated. Congenitally Corrected Transposition (L-Transposition) the L-transposition anomaly is characterized by atrioventricular discordance and ventriculoarterial discordance; thus the systemic ventricle is the morphologic right ventricle. Patients may have a successful pregnancy so long as the ejection fraction of the systemic ventricle is preserved and no significant associated anomalies are present. The most common of these is systemic atrioventricular valve (tricuspid) regurgitation, which contributes to systemic ventricular dysfunction. An occasional adult will be seen who has not had previous surgery or in whom palliation was achieved with a surgically created shunt. In such cases, pregnancy may pose a risk, depending on the degree of cyanosis, as noted earlier. The fall in peripheral resistance augments the right-to-left shunt through the ventricular septal defect, causing worsening cyanosis, with risk to both mother and fetus. For those patients with previous definitive surgical repair, a careful assessment of any hemodynamic residua and sequelae should be undertaken before advice is given about the safety of a pregnancy. The clinical and echocardiographic evaluation should focus on the presence of lesions, such as residual pulmonary regurgitation, which is common after repair, and associated right ventricular dysfunction and tricuspid regurgitation. Additional "volume lesions," such as ventricular septal defects and aortic regurgitation, as well as residual right ventricular outflow tract obstruction, should be evaluated. For those women with an effective surgical repair, good exercise capacity, and minimal residua, pregnancy may be well tolerated, provided that they are properly managed. In the absence of a parental chromosomal abnormality and a family history of other congenital cardiac disease, the risk of the fetus having a congenital cardiac anomaly is approximately 5% to 6%, similar to the risk of inheritance of many congenital cardiac lesions. In addition, death may occur from pulmonary embolism or in situ pulmonary infarction. In the largest retrospective review, Gleicher and associates20 reported 44 cases of Eisenmenger syndrome with 70 pregnancies; 52% died in connection with a pregnancy, and 34% of vaginal deliveries resulted in maternal death. Three of four cesarean sections also resulted in maternal death; however, it is likely that those patients represented a higher-risk cohort because they were the most hemodynamically unstable. Termination of pregnancy is the safer option, although in patients with pulmonary hypertension, this too may be a more complex procedure, and cardiac anesthesia probably is helpful in this regard. Low-dose subcutaneous heparin may be administered during bed rest, but the available evidence fails to show that it improves maternal survival. The mode of delivery needs to be determined after careful consideration by the treating physicians. If the vaginal route is selected, it should be performed in an intensive care unit. Epidural analgesia must be administered with due caution to minimize peripheral vasodilation. Recent case reports have suggested a more successful maternal outcome with the use of pulmonary vasomodulator drugs. Nitric oxide can be administered through nasal cannula or facemask, and successful pregnancy also has been reported with intravenous epoprostenol. Sildenafil also has been used, but with all of these agents, maternal death may still occur days or weeks after delivery. In summary, the mortality for pregnant patients with severe pulmonary hypertension is prohibitively high. CardiovasCular disease in speCial populations Transposition of the Great Arteries (D-Transposition) All patients with transposition of the great arteries (D-transposition) will have had surgery in childhood, commonly an atrial baffle procedure (Mustard or Senning operation), which leaves the morphologic right ventricle as the systemic pump. Function of the systemic ventricle should be assessed clinically and echocardiographically before pregnancy, as well as the degree of tricuspid (systemic) atrioventricular valve regurgitation and degree of baffle obstruction, the residual atrial septal defect, and the presence or absence of atrial arrhythmias, which are common complications. In the more recent surgical era, patients are more likely to have had an arterial switch procedure. Residua include aortic and pulmonary regurgitation as well as stenosis of the translocated coronary arteries. These hemodynamics should all be evaluated at the time of pre-pregnancy counseling. Coarctation the evaluation of the woman with repaired coarctation should include an assessment of the coarctation repair site to exclude residual or recurrent coarctation or aneurysm formation and an imaging study to assess the entire aorta to rule out dilation or aneurysm formation, which is most common in the ascending aorta. For patients with mild dilation of the aorta, vaginal delivery with a short second stage is reasonable, but in those with evidence of aortic instability, a cesarean section is preferable. Univentricular Heart and Fontan Operations Women who have undergone univentricular heart and Fontan operations are at increased risk for maternal complications, particularly atrial arrhythmias, which may cause profound hemodynamic deterioration. They are particularly vulnerable to development of thrombosis in the Fontan circuit because of the sluggish flow and prothrombotic state of pregnancy. Function of the single ventricle may deteriorate as a consequence of the volume load of pregnancy, and the risk of miscarriage also appears to be significantly increased. The most common cause in women of childbearing age is a congenital cardiac shunt. When the pulmonary hypertension exceeds approximately 60% of systemic levels, pregnancy is more likely to be associated with complications. In the setting of severe pulmonary vascular disease (Eisenmenger syndrome; see Chapter 62), maternal mortality rate may approach 50%. The volume load of pregnancy may compromise the poorly functioning right ventricle, precipitating heart failure. The fall in peripheral resistance augments right-to-left shunting, thereby contributing to development of cyanosis. Labor and delivery are particularly dangerous, and the highest incidence of maternal death is during parturition and the puerperium. An abrupt decrease in afterload may occur as the baby is delivered, and hypovolemia from blood loss can cause hypoxia, PulmonaryHypertension Because of the declining incidence of rheumatic heart disease in Western countries, valvular heart disease (see Chapter 63) is infrequent in North America but remains prevalent in developing countries. The most common problems encountered are bicuspid aortic stenosis (discussed previously) and mitral stenosis, which tends to worsen during pregnancy because of the increase in cardiac output coupled with the increase in heart rate; this shortens the diastolic filling time and exaggerates the mitral valve gradient. Any decrease in stroke volume causes a further reflex tachycardia, which contributes to an elevated left atrial pressure. Patients should undergo careful echocardiographic evaluation of their mitral valve gradient, valve area, and pulmonary pressures before proceeding with a pregnancy. Exercise echocardiography also may be helpful in delineating the hemodynamic response to effort in terms of mitral gradient and the presence or absence of pulmonary hypertension. Bed rest also may be helpful to slow the heart rate and to minimize cardiac demands. Anticoagulants probably should be given if the patient is on bed rest and certainly should be administered in the setting of atrial fibrillation. When the mother fails to respond adequately to medical management, balloon valvuloplasty may be performed if the valve anatomy is favorable22 and concomitant mitral regurgitation has been ruled out. Surgical valvotomy may be performed but should be reserved for patients with symptoms refractory to medical therapy in whom balloon valvotomy is contraindicated. ValvularHeartDisease 1761 Mitral and aortic regurgitation are fairly well tolerated in pregnancy, provided that the regurgitation is of no more than moderate degree, the mother is symptom-free before pregnancy, and ventricular function is well preserved. Closer monitoring during pregnancy usually is warranted, however, particularly for those with mitral regurgitation, because the left ventricle tends to dilate as pregnancy progresses, and this may exacerbate the degree of mitral regurgitation. Early delivery may be necessary in the setting of maternal hemodynamic compromise. With all anticoagulant regimens, the addition of low-dose aspirin, 75 to 162 mg/day, may confer additional maternal benefit, but data are scant. All anticoagulant regimens, however carefully managed, carry an increased risk to the fetus from the potential for hemorrhagic complications, including placental bleeding, miscarriage, and fetal death. All mothers with mechanical prostheses are best managed by a multidisciplinary team in a center that provides training and expertise in the management of complex heart disease and pregnancy. Pregnancy and Heart Disease Prosthetic Valves Pregnancy for the woman with a prosthetic valve poses risks for mother and baby. The choice of a prosthetic valve for the woman of childbearing age involves a detailed discussion of the relative risks so that she can make an informed decision about whether to select a tissue or mechanical prosthesis. Tissue valves are less thrombogenic than mechanical valves and therefore are less problematic in pregnancy because they do not routinely involve the use of warfarin. The disadvantage is their tendency to degenerate after an average of 10 years, necessitating a reoperation, with its attendant risks and potential mortality. Mechanical prostheses, by contrast, have a greater longevity but require anticoagulation, and whichever anticoagulant strategy is chosen during pregnancy, there is a higher chance of fetal loss, placental hemorrhage, and prosthetic valve thrombosis. Thus each type of valve has a specific risk-to-benefit ratio; the choices are reviewed here. Unfractionated Heparin Unfractionated heparin is a large molecule that does not cross the placenta and does not cause developmental abnormalities in the fetus. It usually is continued until week 13 or 14 of pregnancy, when fetal embryogenesis is complete, and then warfarin is substituted. Some physicians continue heparin throughout pregnancy to avoid any fetal exposure to warfarin, but unfractionated heparin has been shown to be a poor anticoagulant in pregnancy. Studies comparing different anticoagulation strategies have shown that most maternal complications. One meta-analysis by Chan and colleagues25 has shown that use of heparin early in the first trimester virtually eliminated the risk of fetal embryopathy but more than doubled the risk of maternal valve thrombosis, which occurred with a frequency of 9%, compared with 3. When heparin was used throughout pregnancy, the risk of valve thrombosis increased to 33%. Tissue Prostheses the most common types of tissue valves used currently are porcine and pericardial valves. For patients in sinus rhythm, they confer the advantage that warfarin is not required, although many patients take a daily baby aspirin (81 mg). These valves are vulnerable to structural degeneration and calcification, which occurs more rapidly in younger patients. In addition, mitral prostheses tend to degenerate faster than those in the aortic position. Some evidence suggests that pregnancy may accelerate valve degeneration; this potential disadvantage is not universally accepted, however, and other large series have shown no difference in structural valve degeneration in young women who had a pregnancy and those who did not. In some series, the mortality rate for a second valve replacement may be as high as 6%, and it must be recognized that if death occurs after a successful pregnancy, the young child is left without a mother. These findings may vary considerably on the basis of both surgical volume and expertise. Use of homografts poses similar problems of structural deterioration and reoperation. The Ross operation, in which an autograft pulmonary valve is placed in the aortic position and a tissue prosthesis (usually porcine) is implanted in the pulmonary position, is associated with good outcomes during pregnancy when the hemodynamic indices are good. Nonetheless, the Ross procedure essentially exchanges one valvular problem for two, and ultimately the tissue pulmonary prosthesis as well as the aortic prosthesis must be replaced. Low-Molecular-Weight Heparin Low-molecular-weight heparin is an attractive alternative to unfractionated heparin because of its ease of use and superior bioavailability. Maternal deaths have been reported with its use, however, usually associated with valve thrombosis. One retrospective study has reviewed published series using low-molecular-weight heparin between 1989 and 2004. Thromboemboli occurred in 10 of the 81 pregnancies (12%), and all of the patients had mitral prostheses. Low-molecular-weight heparin was used throughout in 60 pregnancies; in 21 pregnancies, it was used only in the first trimester and again at term. In 51 pregnancies, anti-Xa levels were monitored, and in 30 pregnancies, a fixed dose was used. All 10 patients with thromboemboli were receiving heparin throughout pregnancy, and 9 of them were on a fixed-dose regimen. Recent studies have emphasized the importance of avoiding a weight-based heparin regimen, instead recommending optimization of anticoagulation by monitoring anti-Xa levels. This approach also is problematic, however, because the dose requirements change dramatically throughout pregnancy owing to changes in renal clearance and plasma volume. Data remain limited regarding optimal anti-Xa levels, timing of measurement (peak versus trough levels or both), and the frequency of testing. Even with careful and frequent monitoring, valve thrombosis still occurs, with a risk of up to 17% in some contemporary series. There is no perfect strategy, and each modality is associated with some hazard for the mother or the fetus. Before any approach is adopted, it is imperative to explain the risks to the patient. During pregnancy, maternal blood is highly thrombogenic because it contains an increased concentration of clotting factors, with increased platelet adhesiveness combined with decreased fibrinolysis. These changes in clotting parameters contribute to significant risk of maternal valve thrombosis and thromboembolism. The magnitude of the maternal risk is dependent on which valve is involved (the 1762 1. Thus the use of low-molecular-weight heparin remains controversial, with no large prospective series and no evidence-based data to support which levels of anti-Xa should be maintained. This precaution is especially important if epidural analgesia is to be used, because its prolonged effect increases the risk of spinal hematoma.

Presented at the Seventh European Meeting on Hypertension, Milan, Italy, June 9-12, 1995. A recent consensus document acknowledges the lack of data but advocates lifestyle changes in the elderly (salt restriction, exercise, smoking cessation) as initial therapy. Age-related bone loss accelerates in older men and women, contributing to osteoporosis that in turn is a major risk factor for fractures estimated at 40% for women and 13% for men. Thiazides have been shown to preserve bone mineral density compared with placebo in randomized controlled trials and have been associated with higher bone mineral density and a reduction in risk of hip fractures in epidemiologic studies, providing a noncardiac treatment benefit in older patients. Drugs that do not increase urinary frequency may be accepted with higher adherence rates. Table 76-5 presents suggested antihypertensive regimens in older patients based on the presence of hypertension and concomitant conditions. Improved blood pressure control has been found with patient education on medication adherence, low-sodium diet, and exercise, in combination with provider education and pharmacy alerts to providers regarding patient responses to medications. Use of home blood pressure monitoring to improve blood pressure control has produced conflicting results and is not uniformly endorsed. Postural hypotension with a drop in systolic pressure of less than 20 mm Hg or 20% is a risk factor for falls and fractures that are associated with significant morbidity and mortality. Recently, initiation of antihypertensive therapy has been associated with increased risk of hip fractures in community-dwelling elderly persons. It is estimated that 50% to 60% are hypertensive31 and that 30% have postural hypotension. Diuretic therapy appears to control systolic blood pressure in these patients and also may decrease postural hypotension. Postural blood pressure changes should be assessed (after 5 minutes supine, immediately after standing, and 2 minutes after standing) in older patients, and volume depletion should be avoided. Postprandial declines in both systolic and diastolic blood pressure occur in hospitalized, institutionalized, and community-dwelling elderly persons. The greatest decline occurs approximately 1 hour after eating, with blood pressure returning to fasting levels at 3 to 4 hours after eating. Vasoactive medications with rapid absorption and peaks should not be administered with meals. In cases of severe or persistent hypertension despite the initiation of antihypertensive treatment, temporary or permanent discontinuation of angiogenic inhibitor should be considered. CardiovasCular disease in speCial populations CoronaryArteryDisease (See Chapters 50 to 54) Prevalence and Incidence. Estimates based on electronic medical records report almost one half of men older than 80 years of age have coronary disease, as do one third of women. Because of the increasing proportion of women at older ages, however, there are more older women with angina presenting for care. These women have been less likely to receive evidence-based therapy for stable angina, aggressive therapy for acute coronary syndromes, or diagnostic evaluations. Additional Considerations in the Older Patient with Hypertension All guidelines recommend lower initial drug dosages and slower medication titration in older patients and the need to monitor for postural hypotension. Caution is needed with initiation of more than one agent concurrently, and such prescribing is not advised in the frail elderly. Once effective regimens have been identified, combination formulations can be considered to decrease pill burden and increase adherence. Available only as transdermal formulation for patients unable to swallow or who refuse oral medications. In elderly patients with medical comorbid conditions, a reduction in symptoms that permits less strenuous activities but maintains independence and activities of daily living may be a satisfactory goal. Recognizing the increased morbidity and mortality associated with revascularization in the elderly (particularly those 75 to 80 years of age and older and women), and the evidence for equivalent outcomes with optimized medical care, the consensus is that optimal medical therapy should be the initial approach in most older patients. Secondary prevention efforts should target interventions conferring benefit within the anticipated lifespan of the patient. Lifestyle changes of smoking cessation and increased activity provide improvements in a short time frame, whereas benefits of lipid-lowering may take longer. The geriatric literature has also shown that exercise interventions can be performed in the elderly, including frail elderly, and can attenuate some age-related changes in muscle and overall function. Overall mortality and not just cardiovascular risk may be of greater relevance in the elderly population. In estimating risk of all-cause mortality, a survey of data from large populations, including persons undergoing angiography, found that sex-specific risk scores combining complete blood count and basic metabolic profile components and age were highly predictive of occurrence of death at 30 days and at 1 and 5 years. Anginal symptoms are more likely to be absent, or ischemia is more likely to be silent in older patients. Symptoms may be "atypical" and differ from those of classical substernal pressure with exertion. Clinical manifestations may primarily be dyspnea, shoulder or back pain, weakness, fatigue (in women), or epigastric discomfort and may be precipitated by concurrent illnesses. Older patients with self-limited levels of physical exertion may not report symptoms, and in those with altered manifestations of pain resulting from concomitant diabetes or age-related changes, symptoms may occur at rest or during mental stress. Treadmill exercise testing can provide prognostic information in patients able to exercise sufficiently and can also provide information regarding functional capacity and exercise tolerance (see Chapter 50). Exercise testing results can be enhanced by the use of modified protocols beginning with low intensity exercise. Most series report slightly higher sensitivity (84%) and lower specificity (70%) in patients older than 75 years than in younger patients. Pharmacologic stress echocardiography and nuclear perfusion imaging can overcome some of the limitations (see Chapter 13).

N Engl J Med 335:1001, 1996; and Lewis S, Moye L, Sacks F, et al: Effect of pravastatin on cardiovascular events in older patients with myocardial infarction and cholesterol levels in the average range. Risk factors for statin-induced myopathy include age older than 80 (and in women more than men), smaller body frame, frailty, multisystem disease (including chronic renal insufficiency, especially as a result of diabetes), and higher doses. Myopathy may be underappreciated because of other musculoskeletal disorders or pain, or may not be reported because of cognitive impairment. Complaints may be nonspecific or "flulike," with fatigue nearly as commonly reported as muscle pain. Cross-sectional studies of adults report 22% to 23% with musculoskeletal pain during statin use. In older patients, the smallest effective dose of a lipid-lowering agent should be used, and signs and symptoms monitored. Lipid lowering as primary prevention should be reserved for elderly patients with longer life expectancy and accompanied by monitoring for adverse muscle, glucose, and cognitive effects. They make no recommendations for those over age 75 and highlight the need for individualization of choices for patients over 75. These patients tend to be older, have more multivessel disease and comorbid conditions than those in randomized studies and long-term survival rates are lower and complication rates higher than in randomized trials. Postoperatively, longer duration of ventilatory support, greater need for inotropic support and intra-aortic balloon placement, and greater incidence of atrial fibrillation, bleeding, delirium, renal failure, perioperative infarction, and infection are seen in older patients compared with younger patients, with the highest rates in older women and patients undergoing emergency procedures. Older age, comorbidity, female sex, frailty, and dementia have been shown to be risk factors for death and prolonged institutional care after cardiac surgery. CardiovasCular disease in speCial populations Special Considerations with Pharmacologic Treatment in the Elderly Patient with Coronary Artery Disease Marked vasodilation resulting from rapid absorption or higher peak effects of isosorbide dinitrates can exacerbate postural hypotension so agents with smooth concentration versus time profiles such as mononitrates or transdermal formulations may be preferable. A preliminary report of increased bone density in postmenopausal women with transdermal nitroglycerin suggests a potential noncardiac benefit with this agent. Calcium channel blockers, especially the dihydropyridines, can cause pedal edema more frequently in the older patient. Shorteracting formulations can produce or exacerbate postural hypotension and should be avoided. Both beta blockers and nondihydropyridine calcium channel blockers should be avoided in the presence of so-called sick sinus syndrome (sinoatrial disease). Adverse effects of dizziness, constipation, nausea, asthenia, headache, dyspepsia, and abdominal pain reported with use of the piperazine derivative ranolazine are more common in elderly patients, and women may have less exercise benefit with ranolazine compared to men. J Am Coll Cardiol 6:723, 2000; and Bridges C, Edwards F, Peterson E, et al: Cardiac surgery in nonagenarians and centenarians. The possibility of disability or prolonged hospitalization after interventions and especially surgery must be considered and accurately conveyed to the patient and family. For the patient unable to make decisions, involvement of family members or agents is key to decisions that reflect the wishes of the patient. A clear role is recognized for individualized risk assessment and respect for patient preference in the decision-making process. For relief of symptoms: Beta blockers, nitrates, and calcium channel blockers can be used. For secondary prevention: Antiplatelet drugs and lipid-lowering agents may be indicated. Pharmacologic treatments must incorporate age-related adjustments in dosing and consider altered reflex responses and drug interactions. For lower- or intermediate-risk patients, treatment choices should be based on consideration of patient and family preferences, quality-oflife issues, end-of-life preferences, sociocultural specifics, and the experience and capabilities of the clinical center. All pharmacologic regimens must be adjusted for renal status and patient body size. Recommendations are based on extrapolations from younger and less sick populations. These trials used contemporary diagnostic strategies, enrolling patients with positive assays for troponins or other cardiac biomarkers that included "younger" elderly patients (mean age usually <65 years) with fewer comorbid conditions than typically are encountered in clinical practice. For higher-risk patients, early intervention reduced composite adverse short-term cardiovascular endpoints. Guidelines acknowledge that further study could provide a stronger evidence base for an initial conservative/selective invasive strategy in stabilized patients treated with intensive medical therapy as it has for stable angina patients (see earlier). Increased implementation of evidence-based pharmacotherapy is needed with greater attention to appropriate dose selection or correction for body size and drug clearance. Individual agents, mechanisms of actions, and dosing guidelines are discussed elsewhere in this book (see Chapters 50 to 55 and 82). The sex of patients presenting with acute coronary syndromes (see Chapters 52, 53, and 54) changes from predominantly men in middle age, to equal numbers of men and women presenting between the ages of 75 to 84, to a female majority beyond age 80 years. Mortality is at least three times higher in the patient older than 85 years than in the patient younger than 65 years. Sudden pulmonary edema or neurologic signs and symptoms such as syncope or stroke also may be presenting features. Noncardiac comorbid conditions such as chronic 1727 fibrinolytic therapy within 30 minutes of hospitalization is recommended,68 with European guidelines extending this window to within 12 hours of symptom onset. In-hospital mortality was related to age, and a survival advantage with reperfusion was found only for those younger than 75 years of age. These data show that results in the community setting do not currently parallel those reported in clinical trials, and guidelines acknowledge the importance of an individualized approach to reperfusion. With the caveat of adjusting dosing for age and renal status, recommendations are the same as in younger patients. Screening should be performed using either a simple twoquestion test followed by additional evaluation for patients with answers suggesting the presence of depression, the nine-item Patient Health self-report questionnaire screening instrument (in literate patients), or the geriatric depression screen. Randomized trials of multiple hormone replacement therapies have shown overall lack of cardiovascular morbidity or mortality benefit and potential harm in postmenopausal women. Neither estrogen, estrogen plus progesterone, raloxifene, nor tamoxifen can be recommended for cardiovascular disease prevention or treatment. Those at high risk for intracerebral hemorrhage include patients older than 75 years, women, African Americans, smaller patients, (<65 kg in women and <80 kg for men), previous stroke, and systolic blood pressure greater than 160 mm Hg. Some of the increased bleeding risk in the elderly population is potentially correctable, inasmuch as it has been shown to be due in part to administration of inappropriately high doses of anticoagulants as well as fibrinolytic agents. Rehabilitation Programs Feasibility and improvement with exercise interventions has been shown for the elderly, including the frail elderly. Traditional cardiac rehabilitation incorporates exercise training in addition to patient education and counseling76 (see Chapter 47). Traditional rehabilitation at clinical centers incurs cost, travel time, and requires transportation that may limit participation of some elderly. A recent Cochrane review of data from 12 randomized trials compared the effectiveness of home-based rehabilitation against supervised center-based cardiac rehabilitation. Short-term morbidity can potentially be further reduced with greater attention to medication dosing and prevention of adverse effects of intensive medical and interventional management. Therapy for the older patient with an acute coronary syndrome should be individualized with therapeutic choices considering medical and cognitive status, anticipated life expectancy, and patient or family preferences and with early invasive strategies directed to high-risk groups that may have the greatest benefit. Stroke is the third leading cause of death and the most common cause of major adult disability in the United States (see Chapter 59). The risk of stroke increases with age and doubles for each decade after age 55 years. Framingham data estimate the 10-year probability of stroke at 11% in men at age 65 years and 7% for women age 65. At age 80, the probability increases to 22% and 24% for men and women, respectively. Carotid stenosis is responsible for approximately 15% to 25% of strokes and atrial fibrillation for approximately 15%.

A bimodal peak in age has been noted in several studies, with onset in the first decade and a second peak occurring in the second to fourth decades of life. Although one or more infectious agents could be causal, no consistent unifying infectious cause has been established. Environmental exposure to cerium, a rare element present in affected areas, has also been considered. Family-based disease has been observed in several reports, but whether familial predisposition is related to environmental or genetic causes, or to both, remains unknown. In most cases heart failure symptoms from left or right restrictive physiology predominate the clinical findings and include dyspnea on exertion, paroxysmal nocturnal dyspnea, and edema. Ascites, at times a prominent feature, is common to all the endomyocardial diseases. Cardiovascular imaging shows restrictive filling with apical fibrosis that commonly involves the mitral and tricuspid subvalvular apparatus, accompanied by atrial enlargement. As noted earlier, successful surgical resection of the endocardial fibrosis with valve repair or replacement can have a dramatic effect on symptoms and survival, although the operation itself is associated with a significant risk for morbidity and mortality.

Menon S, Michels V, Pellikka P, et al: Cardiac troponin T mutation in familial cardiomyopathy with variable remodeling and restrictive physiology. Sequencing of the exome, defined as the 1% to 2% of the human genome that encodes the approximately 19,000 genes, has greatly facilitated progress in understanding the genomic basis of the cardiomyopathies. Over the next few years the genomic information reviewed herein, limited in most cases by mutation surveys of one or a few candidate genes, will give way to comprehensive genome-wide strategies, either by exome or by genome sequencing, to identify and understand rare and common variants relevant to disease susceptibility and cause, including structural and other nonprotein coding genomic variants, in much larger populations of patients with cardiomyopathy. This will enable a more comprehensive and insightful understanding of the genomic basis of human disease, including that affecting the myocardium. Our present rudimentary understandings of "mendelian genetics," an oversimplified concept of "single-gene" genetics, is rapidly evolving into enormous complexity. Indeed, the rapid advances in this field suggest that the principal role of the cardiologist will change from recognizing and managing established disease, as is the case today, to interpreting and applying genetic information for prevention and treatment in 2020 and beyond.

J, Late gadolinium enhancement indicative of replacement myocardial fibrosis (arrows). The mitral valve may be more than twice normal size as a consequence of elongation of both leaflets, or segmental enlargement of only the anterior leaflet or mid-scallop of the posterior leaflet. The preferred first option (*) for clinical testing family members is usually with cardiac imaging and electrocardiography to identify phenotype-positive relatives. Failure to identify the causative mutation in the proband is an indeterminate result that provides no useful information and precludes predictive testing in family members. Accordingly, the genetic test results in the proband will be actionable in terms of family screening in only a minority of cases. Marked and centrally located mitral regurgitation jets usually suggest an intrinsic valve abnormality. Alternatively, gradients can be augmented by circumstances in which arterial pressure or ventricular volume is reduced. Consumption of a heavy meal or alcohol can also transiently increase subaortic gradients and produce exertional dyspnea. This, in turn, serves as an electrophysiologically unstable substrate and a trigger for reentry ventricular tachyarrhythmias and sudden death. Such patients occasionally become refractory to medical management, requiring heart transplantation. F, G, Echocardiographic apical four-chamber view at end-diastole and end-systole, respectively, showing hypertrophied anterolateral papillary muscle appearing to insert into anterior mitral leaflet, creating midventricular muscular obstruction (arrow). J Cardiovasc Transl Res 2:510, 2009 with permission from Springer; and Olivotto I, Girolami F, Nistri S, et al: the many faces of hypertrophic cardiomyopathy: from developmental biology to clinical practice. A, B, Echocardiographic apical the cardiomyocyte level actively contribute to diastolic dysfunction. Such variability, together with the characteristic lack of radiation of the murmur to the neck, aids in differentiating dynamic subaortic obstruction from fixed aortic stenosis. Patients also may experience impaired consciousness with syncope or near-syncope and lightheadedness potentially (but not always) explained by arrhythmias or outflow obstruction. Palpitations are common and may be related to ventricular or supraventricular tachyarrhythmias. The nature and severity of symptoms may be similar in patients with or without outflow obstruction. Affected patients at either extreme of this age range appear to have the same basic disease process, although not necessarily the same clinical course. Such patients may proceed along specific adverse pathways,1 punctuated by clinical events that alter their natural history and ultimately dictate targeted treatment strategies: (1) sudden and unexpected death; (2) progressive heart failure with exertional dyspnea and functional limitation (with or without chest pain); and (3) atrial fibrillation, with the risk for embolic stroke and heart failure. For secondary prevention, these are prior cardiac arrest and sustained ventricular tachycardia. To arbitrate prophylactic implantable defibrillators decisions in patients for whom risk level remains ambiguous after assessment by the conventional risk factor algorithm. Therefore it is not possible to provide complete reassurance that a normal echocardiogram at maturity unequivocally defines genetically unaffected status. However, this strategy is not advisable in the presence of variants of unknown significance. At this advanced age, the risk of complications, particularly sudden cardiac death, is low. PreparticipationScreening Detection of cardiovascular abnormalities with the potential for unexpected and unpredictable sudden death, associated with intense physical training and competition, is a major objective of preparticipation screening for high school and college-age sports participants. In the United States, customary screening practice dictates obtaining a complete personal and family medical history and physical examination. In patients with outflow obstruction, disopyramide may be a third option (in combination with a beta blocker) to ameliorate symptoms. Although a trial of beta blockers is usually the first option, there is no evidence that combining beta blockers and verapamil is advantageous, and together they may lower heart rate and/or blood pressure excessively. Such decisions are tailored to individual patients after consideration of lifestyle modifications, hemorrhagic risk, and expectations for compliance. Beta blockers and verapamil usually are administered to control heart rate in patients with persistent atrial fibrillation. Age range takes into consideration individual variability in achieving physical maturity, and screening in some patients may be justified at an earlier age; initial evaluation should be performed no later than early pubescence. Some surgeons now perform an aggressive myectomy with muscular resection extended more distally within the septum to the base of the papillary muscles. Expected operative mortality has decreased steadily and is now less than 1% at selected myectomy centers. As a result, long-term follow-up studies have reported relief of symptoms in 85% of patients during periods of up to 25 years. Myectomy patients have achieved extended survival equivalent to that expected in the general population and superior to that of nonoperated patients with outflow obstruction,75 and possibly reduced sudden death rate. Note that adverse pathways are not necessarily mutually exclusive, in that patients may progress at various times along more than one pathway. No data are available on benefit of drug treatment to asymptomatic patients, although in clinical practice, beta blockers or calcium channel blockers are sometimes administered prophylactically. Usually beta blockers and calcium channel blockers, disopyramide (in the presence of obstruction), and possibly diuretics (administered judiciously). Although modest reduction in subaortic gradient may result from pacing in some patients, this benefit is much less consistent compared with that achieved by myectomy or alcohol ablation. Several randomized studies demonstrated that subjectively perceived symptomatic benefit from pacing was not accompanied by objective evidence of improved exercise capacity and therefore appeared to be largely a placebo effect. Percutaneous alcohol septal ablation is an alternative to myectomy in selected patients, and involves injection of 1 to 3 mL of 95% alcohol into a major septal perforator coronary artery to create necrosis and a permanent transmural myocardial infarction localized to the proximal ventricular septum. The remaining unresolved question with use of alcohol septal ablation11,88,89 is the important issue regarding the clinical consequences of alcohol-induced transmural scars, which represent a potentially unstable arrhythmogenic substrate that could potentially trigger lethal ventricular tachyarrhythmias and increase sudden death risk in already susceptible patients. Maternal morbidity and mortality is confined to a very small subset of symptomatic women with high-risk clinical profiles. Vegetations most commonly involve anterior mitral leaflet or septal endocardium at the site of mitral valve contact. Dilemmas in nomenclature characterizing hypertrophic cardiomyopathy and left ventricular hypertrophy. Efforts to define the proper role of alcohol septal ablation relative to surgical septal myectomy in the management of severely symptomatic drug-refractory patients with outflow obstruction will continue, and a more precise understanding of the applications of commercial genetic testing can be expected with the advent of next-generation sequencing.
