We present a report of a postoperative left ventricular-right atrial (LV-RA) communication after aortic valve replacement. Such intracardiac defects are rare but encountered occasionally after valve surgery. The diagnosis was made by use of transesophageal echocardiography with echo-Doppler and color-flow imaging. Complications of LV-RA shunts and differential diagnosis are discussed.

Background & aim: Congenital heart disease is one of the most common malformations at birth that require timely recognition and treatment. The aim of this study was to determine the prevalence and etiology of detected heart murmurs and association between congenital heart disease and heart murmurs. Recognition of murmurs etiology would help us to manage and treat them properly. Methods: In this...

We studied the effect on the circulation of the catecholamines isoproterenol, dopamine, and dobutamine in chronically instrumented lambs with aortopulmonary left-to-right shunts (ages 11 to 87 days) and without shunts (ages 8 to 97 days). Infusion of 0.1 ,ug/kg/min isoproterenol or 10 gvg/kg/min dobutamine markedly increased heart rate and systemic and pulmonary blood flows, while stroke volume...

Cine magnetic resonance imaging (cine MRI) was used to evaluate the cardiac structures and blood flow in congenital heart diseases with left-to-right shunts. Fifteen children with left-to-right shunts which were confirmed by echocardiography or angiography were investigated in the present study. Five children each had atrial septal defect, ventricular septal defect, and complete endocardial cus...
