Abstract
-
The four most common types of congenital malformations involving the right atrium(RA) and the coronary sinus(CS) are congenital enlargement of the RA, single RA diverticulum, multiple diverticula of the RA, and aneurysm of the RA or CS. A previously healthy 6year-old child was presented with signs of upper respiratory tract infection. Chest X-ray and echocardiogram revealed a severely isolated right atrial enlargement. The abnormally dilated right atrim was widely resected under cardiopulmonary bypass. Pathology revealed multifocal myocardial loss associated with mild fibrotic changes of the endocardium and epicardium. Our experience on this rare congenital disease is presented along with a review of the literature.
