A Case of Coronary Sinus Atresia with a Total Anomalous Cardiac Venous Drainage to the Left Atrium without Persistent Left Superior Vena Cava: Imaging Findings on Cardiac CT

Abstract

The coronary sinus (CS) is the venous drainage system of the heart. CS ostium atresia is a rarely seen cardiac malformation. Congenital atresia of the CS is usually found together with persistent left superior vena cava (LSVC) and other cardiac malformations. However, isolated congenital atresia of the CS is very rare. We present a rare case of isolated congenital atresia of the CS connecting the left atrium and coronary veins without persistent LSVC in a 58-year-old female.

Failure to wean off after a routine total anomalous pulmonary venous connection operation: An uncommon association

“…[ 7 ] Direct drainage to the left ventricle or pulmonary artery has also been reported. [ 8 ] The embryological basis for the various drainage variations remains speculative. The anatomic variations have an important bearing for cardiac surgical procedures or during cardiac device implantation.…”
