Anomalous Connection of the Right Superior Vena Cava to the Left Atrium in a Child with Bilateral Superior Vena Cavae: An Unusual Cause of Cyanosis

Abstract

Anomalous drainage of the right superior vena cava into the left atrium (LA) has been previously reported in the medical literature. We present a unique case of a child who had two superior vena cavae, a left superior vena cava that drained normally through the coronary sinus to the right atrium, and a right superior vena cava that drained anomalously to the LA.
