Persistent left superior vena cava (VCSSP) is the most frequent systemic venous return anomaly. It often occurs during right heart catheterization (0.1%) and is associated with right superior vena cava aplasia in 10 to 33%. It can lead to the development of a left superior venous system mirroring the normal right return. It runs between the pulmonary veins and the left auricle, to join the coronary sinus. Sometimes the coronary sinus does not communicate directly with the right atrium but drains into the VCSS. An increased incidence of arrhythmias has also been reported in the presence of venous drainage abnormalities. Its discovery has implications as it can create difficulties in the insertion of central venous catheters, cardiac surgery, thoracic and PMK implantation.VCSSP in the absence of the right superior vena cava (VCSD) is a rare congenital anomaly.
