A Case of Persistent Left Superior Vena Cava without Coexistence of Right Superior Vena Cava

Congenital abnormalities of superior vena cava are rare and usually seen in association with other congenital heart diseases. In the absence of any congenital cardiac abnormality the persistent left superior vena cava with noexisting absence of right superior vena cava is quite rare. In this report we present an asymptomatic case of persistent left superior vena cava having atrial fibrillation with no associated congenital heart disease.
