Background: Chronic obstructive pulmonary disease (COPD) and heart failure are prevalent comorbidities affecting a vast proportion of the world population, responsible for significant morbidity and mortality, their coexistence is more frequent than previously recognized that poses important diagnostic and therapeutic challenges. We intend to determine the prevalence of concomitant left ventricu...
Background Late failure of systemic right and single ventricles is difficult to predict. Approximately 1/3 of subjects with congenitally corrected transposition of the great arteries (ccTGA) have congestive heart failure by the fifth decade and 2/3 of subjects with ccTGA and significant associated defects have congestive heart failure by the age of 45 years. Perfusion defects have been identifi...
BACKGROUND A malpositioned heart with apicocaval juxtaposition may complicate the management of patients with functional single ventricles when total cavopulmonary connection is performed. We reviewed our experience with extracardiac total cavopulmonary connection in patients with apicocaval juxtaposition with a special focus on route selection and outcomes. METHODS Of 68 patients who underwe...

A description is given of simultaneous tape records from four well-shielded crystal detectors placed on the anterior chest in the projections of the right atrium, pulmonary artery, ventricles, and lung vessels alone. Single intravenous injections of I human serum albumin were made. Cardiac outputs calculated from the observed data compare favorably with those obtained by catherization. Use of t...
A 39-year-old man with no significant past medical history and no conventional coronary risk factors presented with a history of gradually progressive exertional dyspnea and a systolic heart murmur. Chest x-ray showed an enlarged cardiac silhouette with pulmonary plethora. Initial assessment by transthoracic echocardiography demonstrated mild mitral regurgitation but also revealed an enlarged c...
