Biomarkers in chronic heart failure have been identified which potentially meet some or all of these criteria generic viagra extra dosage 120 mg erectile dysfunction treatment in vadodara, including those associated with hemodynamic abnormalities cheap viagra extra dosage 150 mg with mastercard erectile dysfunction drugs egypt, myocardial inflammation effective 130mg viagra extra dosage erectile dysfunction doctor delhi, myocardial fibrosis, myocardial necrosis, and remodeling (1). The ideal biomarker in heart failure would provide diagnostic and prognostic information; however, to date no biomarkers have clearly been able to do so with sufficient sensitivity and specificity despite a proliferation of potential biomarkers in the literature over the past decade (133). They also appear to have antifibrotic properties as well as other properties that contribute to processes that mitigate the adverse myocardial remodeling that occurs in chronic heart failure (137). Other biomarkers are available, but are not as widely used in clinical practice as the natriuretic peptides. Some biomarkers are more conventionally regarded as indicators of inflammation, but can be properly regarded as cardiac biomarkers as well. Studies of troponin as a biomarker in pediatric heart failure are generally limited to use of this biomarker for the detection of anthracycline cardiotoxicity, with mixed results (160,182). Management of Chronic Heart Failure For infants and children in whom symptoms of heart failure are secondary to a congenital heart defect with increased left-to-right shunting of blood, management after diagnosis should primarily be directed toward surgical repair of the defect. In most cases, efforts should be made to achieve complete repair of the defect if possible, recognizing that certain anatomic defects are not amenable to complete correction. Additionally, patient-specific factors and comorbidities, for example, very low birthweight, or multiple extracardiac abnormalities, may not permit complete repair of an otherwise straightforward defect in a single operation. Medical management in symptomatic infants and children with heart failure symptoms often involves medications and feeding strategies to optimize cardiovascular status and nutritional status prior to surgery. Diuretics bring about rapid relief of pulmonary and systemic venous congestion, effecting improvement in tachypnea, tachycardia, and hepatomegaly. Beta-blockade with propranolol has been demonstrated to reduce heart rate, respiratory rate, heart failure symptoms, and improve growth in infants with heart failure from large left-to-right shunts (186,187,188,189,190). Whether patients with heart failure should be managed exclusively by heart failure specialists remains controversial; there are little conclusive data available in the adult heart failure field (194) and no literature in pediatrics with respect to this important issue. This has led to the need for practitioners with specialized skill sets in advanced heart failure management. Formal board certification in adult heart failure has recently become available to graduates of adult cardiology training programs (195); it is not yet available to pediatric cardiology trainees, although several pediatric cardiology training programs offer advanced “fourth year” fellowships in advanced heart failure and heart transplantation. An important aspect of chronic heart failure management has been the solid evidence base upon which many well-established heart failure therapies in adults are founded. In adults, most of the accepted therapeutic modalities have been tested rigorously in randomized fashion, frequently in thousands of patients. In children, several factors have made comparably rigorous studies of heart failure therapies much more challenging. It is noteworthy that none of the drugs shown to have a survival benefit in chronic heart failure in adults have had similar effects demonstrated in children (196). The reasons for this are numerous and complex, but include the relative rarity of heart failure in children and the difficulty recruiting subjects to perform adequately powered clinical trials, the use of surrogate end points (i. As such, the evidence base for much of chronic heart failure therapy in children is derived from the experience in the adult literature, combined with a limited number of randomized studies, uncontrolled studies, consensus opinion, and accumulated experience. The symptoms of chronic heart failure exist along a continuum and therapies are available that can be tailored on an individual basis according to the severity of illness. A proposed schema for heart failure medical management with escalating disease severity is shown in Figure 73. For asymptomatic outpatients with only imaging evidence of ventricular dysfunction or for those with mild symptoms of chronic heart failure, introduction of oral medication therapy alone may be appropriate. The evidence base for these medications and major issues associated with these medications will be discussed below. Diuretics Diuretics are frequently employed to control symptoms and/or signs of extravascular volume overload, such as orthopnea, dyspnea, peripheral edema, hepatomegaly, or ascites. With the exception of aldosterone antagonists, conventional diuretics (loop diuretics, thiazide diuretics) block specific ion transport proteins in renal tubular cells and thereby inhibit the reabsorption of solutes (198). In doing so, free water is retained in the convoluted tubule and collecting duct, allowing the reduction of systemic and pulmonary venous pressures (199). They may be used in acute exacerbations of chronic heart failure or as part of a chronic medical regimen in patients who are dependent on their administration for maintenance of a euvolemic state. Loop diuretics (furosemide, bumetanide) are typically used as first-line agents, with thiazide diuretics (chlorothiazide, metolazone) added for refractory fluid retention, although there is no clear evidence to support superiority of one class over the other. In the acute decompensated state, loop diuretics may be given in bolus or continuous doses, with equivalent effect on symptom relief (200). In adult practice, it has traditionally been held that diuretics provide symptomatic benefit and improved exercise capacity only, without survival benefit. A recent meta-analysis of diuretic regimens in adults with heart failure suggests a survival benefit, albeit from trials with small numbers of participants (201). To circumvent this undesired effect in diuretic-dependent patients, ultrafiltration has been proposed (203); however, this has limited application in pediatric patients outside of extracorporeal support due to practical considerations. Diuretic resistance is also a concern with long-term use, which may be caused by noncompliance, concomitant use of nonsteroidal anti-inflammatory drugs, and diminished renal natriuretic effect owing to compensatory hypertrophy and hyperplasia of epithelial cells of the distal convoluted tubule leading to increased reabsorption of sodium (204). Once noncompliance has been excluded, strategies to alleviate diuretic resistance include increasing diuretic dose and frequency, adding an additional class of diuretic (usually a thiazide), and considering the specific diuretics metolazone (205) and tolvaptan (206,207), which may be successful at effecting diuresis in edematous or diuretic-resistant patients (208). However, there are no data available regarding the use of metolazone or tolvaptan in pediatric patients. Angiotensin-Converting Enzyme Inhibitors and Angiotensin-Receptor Blockers Since the mid-1980s, afterload reduction of the left ventricle through systemic vasodilation has been a basic therapeutic premise of heart failure. The secondary composite outcome of death and/or hospitalization for heart failure was not different between groups, but all-cause mortality was significantly lower in the losartan group. For example, in a small study of pediatric patients with idiopathic dilated and restrictive cardiomyopathy, increases in stroke volume and cardiac index with a corresponding decrease in systemic vascular resistance were seen after administration of captopril (223). Administration of a single dose of enalapril to children with asymptomatic chronic mitral regurgitation was reported to reduce the degree of mitral regurgitation and increase left ventricular ejection fraction by echocardiography in another small study (224). In fact, in this study, cardiac index was decreased at peak exercise compared to resting conditions in the enalapril group compared to the placebo group. These results are difficult to reconcile with other published studies, but must be viewed in light of small sample size and the use of surrogate endpoints such as exercise capacity as a primary endpoint, which has been shown to be problematic in heart failure trials (226). In a recent double-blind, placebo-controlled trial infants with single ventricle physiology who received enalapril during the first year of life, there were no differences between enalapril and placebo groups with respect to ventricular function, serum brain natriuretic peptide concentration, heart failure class, somatic growth, or mortality at 14 months of age (227). The cardiotoxic effects of chemotherapeutic drugs administered in common treatment regimens for childhood malignancies has been well documented (118). Most commonly, anthracycline agents (doxorubicin, daunorubicin) are the main causes of cardiotoxicity, which generally manifests as a dilated cardiomyopathy with insidious onset. In a study of 18 patients with anthracycline cardiotoxicity enalapril administration was associated with improvements in echocardiographic measures of left ventricular function, early and at medium term (lasting 6 years), but all deteriorated over time thereafter. Of note, all of those with symptomatic heart failure at the beginning of the study had either died or undergone heart transplantation by the conclusion of the study (median follow-up, 10 years) (228). In a larger study, administration of enalapril, compared to placebo, in 135 childhood cancer survivors who had received anthracycline chemotherapy with certain echocardiographic, electrocardiographic, or exercise testing abnormalities did not have effects on cardiac index measured at exercise testing, but did have favorable effects on reducing left ventricular end-systolic wall stress (229). After the first three years, there was no difference in left ventricular ejection fraction between perindopril and placebo; however, at the end of the second phase of the trial in which all patients received perindopril, more patients in the placebo group had left ventricular ejection fractions of less than 45% than the perindopril group, leading to the conclusion that perindopril delayed the onset of ventricular dysfunction in the perindopril-treated group (230).

The atrial appendages are committed to their respective atria and have distinctly different morphology order viagra extra dosage 120mg without prescription erectile dysfunction vascular disease. The right atrial appendage is more anterior purchase generic viagra extra dosage lipo 6 impotence, broad-based discount viagra extra dosage 200 mg amex erectile dysfunction caused by prostate surgery, and triangular in appearance. It is best visualized in the subcostal sagittal view and the parasternal long-axis view (Fig. The left atrial appendage is relatively posterior in location and has a long and narrow appearance. The unique left atrial septal structure is the septum primum, the flap valve of the foramen ovale seen in the apical and subcostal coronal and sagittal views (Fig. In atrial situs solitus, the right atrium is located on the right and receives flow from the systemic veins and the coronary sinus. In heterotaxy syndrome with bilateral right- or left-sidedness and common atrium, the atrial septal structures will not be obvious and atrial situs will be indeterminate or ambiguous. Systemic Veins and Right Atrium The innominate veins are identified in the suprasternal short-axis view. This may require the use of agitated saline contrast that is injected into a left arm vein. The size and possible unroofing of the coronary sinus can be assessed in a posterior sweep from the standard apical four-chamber and parasternal long-axis views. Atrial Septum The atrial septum is examined in the subcostal coronal and sagittal views. The retroaortic (anterior–superior) rim, the tissue between the aorta and defect, can be assessed in the parasternal short-axis view. Superior and inferior vena caval sinus venosus defects are best seen in the subcostal sagittal view. The transducer should be swept posterior and rightward to investigate possible associated partial anomalous pulmonary venous return. The ostium primum defect is related to the crux of the heart and is best seen in the apical four-chamber view. A coronary sinus defect is visualized by sweeping the transducer posterior from the standard apical four-chamber view. Pulmonary Veins and Left Atrium The pulmonary veins can be identified in multiple imaging planes, including the suprasternal short-axis (Fig. Color Doppler with a low-velocity aliasing limit can aid in visualizing the individual pulmonary veins (29). Unlike systemic venous anomalies, in which color Doppler demonstrates flow coursing toward the heart, these anomalous pulmonary venous pathways will have low-velocity color Doppler flow coursing away from the heart, often the first sign alerting the echocardiographer to one of these conditions. Membranes, such as a supravalvar mitral ring and cor triatriatum, can be identified in the apical four-chamber view. The relationship of these membranes relative to the left atrial appendage is diagnostic. This type of membrane may be associated with hypoplasia of the mitral valve annulus. The pulmonary veins drained to a pulmonary vein confluence immediately superior to the roof of the left atrium. Atrioventricular Connection Type The next order of business for the echocardiographer is to delineate and describe the type and morphologic characteristics of the atrioventricular connection (Fig. The septal structures of the atrioventricular valves serve as the only consistent feature allowing morphologic diagnosis. The tricuspid valve has multiple chordal attachments to the ventricular septum (septophilic), seen best in the apical four-chamber view. On the other hand, the normal mitral valve has no chordal insertions to the ventricular septum (septophobic). In addition, the hinge point of the septal leaflet of the tricuspid valve is inferior to the hinge point of the anterior leaflet of the mitral valve. Because each atrioventricular valve is associated with its respective ventricle (i. Instead, there is a venous structure that is adjacent and slightly posterior to the aorta. The structure is also rightward of the aorta indicating that it is an azygos continuation of interrupted inferior vena cava. Atretic atrioventricular connections are easily identified in the apical and subcostal views. The relationships of the atrioventricular valves to each other in double-inlet connections are explored in the parasternal views. The five leaflets of the common atrioventricular valve (superior/anterior bridging, right superior, right mural, inferior/posterior bridging, and left mural) are best seen in a right anterior oblique subcostal view (midway between the coronal and sagittal planes). The degree of bridging of the superior leaflet and its attachments are identified, allowing for Rastelli classification (Fig. Straddling and criss-cross connections are seen in the apical four-chamber and subcostal views. A straddling atrioventricular valve has attachments to the contralateral ventricle, whereas overriding refers to the valve annulus being partially displaced over the contralateral ventricle in these views. Tricuspid Valve The tricuspid valve is examined in the parasternal long-axis plane (sweeping right from the standard plane), the apical four-chamber view, and the subcostal coronal and sagittal views. The septal leaflet and its attachments to the interventricular septum are best seen in the apical four-chamber view. Also, in this view, the inferior (posterior) leaflet (with a slight posterior sweep) or the anterior leaflet (with a slight anterior sweep) is seen on the lateral portion of the right ventricular free wall. The anterior leaflet and its attachments to the conal papillary muscle (Lancisi) are best visualized in the subcostal coronal view sweeping anteriorly. In the evaluation of Ebstein anomaly of the tricuspid valve, the degree of atrialization of the right ventricle is assessed from the apical four-chamber view. The inferior (posterior) mural leaflet is seen with a slight posterior sweep from the apical four- chamber view. A portion of the anterior mural leaflet can be seen with an anterior sweep from the apical four- chamber view but the subcostal coronal view is required to visualize the displacement of the anterior leaflet into the right ventricular outflow tract and the degree to which it may cause obstruction. The tricuspid valve annular dimension, which is important to evaluate in conditions with right ventricular hypoplasia (e. Mitral Valve The mitral valve is visualized in the parasternal, apical four-chamber, and subcostal coronal and sagittal views. The size of the mitral valve annulus, which is important in determining suitability for biventricular repair in cases of relative left-sided hypoplasia, should be measured in orthogonal planes of the parasternal long-axis and apical four-chamber views. The papillary muscles, important to assess for repair of complete atrioventricular septal defect and for diagnosing parachute mitral valve, are best visualized in the parasternal short-axis and subcostal sagittal sweeps. Mitral stenosis is assessed in the parasternal long axis and the apical four-chamber views, where the degree of leaflet excursion can be seen clearly.
