Presented is a case of Persistent left superior vena cava draining into the right atrium through coronary sinus and finally opens into Right Atrium. Abnormalities of the vascular system are more commonly seen due to its importance in circulation. Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the in nominate vein fails to regress. The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%–0.5% of the general population. Normally the superior vena cava is a single vascular structure formed by the union of right and left brachio-cephalic veins which are in turn formed by the union of corresponding internal jugular and subclavian veins of corresponding side, draining the head and neck as well as the superior extremity. During routine dissection in the Department of Anatomy, Jaipur National University Institute for Medical Sciences and Research Centre (JNU IMSRC) Jaipur. We found persistent left superior vena cava in a 64-year-old male cadaver. Both the vena cavae were formed as continuations of brachiocephalic veins of the corresponding side. The persistent left superior vena cava opened into the enlarged coronary sinus that drained into the right atrium between the opening of inferior vena cava and right atrio-ventricular orifice it has important clinical implications in certain clinical interventions. It may complicate placement of cardiac catheters or pacemaker leads.
