Abstract
Persistent left superior vena cava is an uncommon vascular anomaly; however it is the most common anomaly of the thoracic venous system. It may be stand alone or associated with other congenital heart diseases and even other extracardiac anomalies. It is due to a lack of regression and adsorption of the left anterior cardinal vein. The persistence of this vessel renders a left subclavian approach for interventions on the right heart a challenge. It may be responsible for arrthymiias. We present a report of a persistent left superior vena cava draining into the coronary sinus with a coexisting normal right superior vena cava. Keeping in mind its widespread implications on cardiac procedures and a causative factor of cardiac disturbances we have considered its course, embryological source and clinical significance.
