Persistent left superior vena cava (LSVC) is the commonest congenital anomaly of the thoracic venous system. It is within the group of anomalous systemic venous return (ASVR) and the group is subdivided in cephalic, involving the superior vena cava (SVC) and caudal, involving the inferior vena cava (IVC) types. It is also important to recognise that there can be a persistent LSVC with or without a normal right superior vena cava (RSVC). In most cases, a persistent LSVC drains into the right atrium via the coronary sinus without any clinical symptoms. In this article we discuss embryology, diagnostic and further management approaches and a review of the literature related to persistent LSVC.
