Abstract


Persistent Left Superior Venacava (PLSVC) is the most common venous anomaly affecting the thoracic venous system. If present, the usual site of drainage of a PLSVC is the right atrium via the coronary sinus. Here, we present a case of PLSVC which drained into left atrium instead. The patient, thus, had right to left shunt, making him persistently hypoxemic despite supplementary oxygen. This condition is extremely uncommon and can be easily overlooked if not specifically searched for.
