This report presents a new, simple and reliable method of quantitating left-to-right shunts from arterial dilution surves. When indicatior (e,g., indocyanine green) is injected centrally (right venticle or pulmonary artery) and blood is withdrawn rapidly from either the aorta or other central systemic artery, in the presence of a left-to-right shunt to(More)
The clinical and morphologic features of hypertrophic cardiomyopathy in 20 patients recognized as having cardiac disease in the first year of life are described. Fourteen of these 20 infants were initially suspected of having heart disease solely because a heart murmur was identified. However, the infants showed a variety of clinical findings, including(More)
Doxorubicin is an effective antineoplastic agent, but it frequently causes dose-related cardiotoxic effects. Because the atrial natriuretic peptide (ANP) level is elevated in children with heart defects, the authors measured the ANP levels in children to determine whether ANP might serve as a simple diagnostic indicator of cardiotoxic effects. Sixteen(More)
Three infants with supraventricular tachycardia and congestive cardiac failure were given verapamil intravenously. In two of the infants, the rhythm was converted to sinus, but the third infant required direct current cardioversion. However, each infant demonstrated hemodynamic decompensation shortly after verapamil administration and required(More)
The usefulness of streptococcal antibody tests anti-streptolysin 0 (ASO), anti-desoxyribonuelease B (anti-DNAse B), and anti-group A carbohydrate (A-antibody) in differentiating rheumatic from non-rheumatic mitral disease was explored. Sera from 154 children with mitral disease were studied. Fifteen of 17 patients with chronic mitral insufficiency (MI)(More)
The specificity of the persistence of antibody to the streptococcal group A carbohydrate for mitral valve disease induced by rheumatic fever was examined. Levels of the antibody were determined in serum samples of 30 patients with rheumatic mitral insufficiency, 30 patients with mitral valve prolapse, and an equal number of normal individuals and patients(More)
