From: Mitral valve repair in patient with absent right superior vena cava in visceroatrial situs solitus
Contrast enhanced CT Thorax scan with the 3D reconstruction of the heart; 1A: anterior view; 1B: left lateral view. The left sided superior vena cava (PLSVC: *) is being formed by the bridging vein (BV), which drains the jugular and subclavian vein. The left brachiocephalic vein is not present since contrast medium was injected via a right cubital vein. PLSVC descended at the left side of the mediastinum leftward of the pulmonary artery and left atrium before draining into the right atrium via a dilated coronary sinus. Ao: Aorta, PA: Pulmonary artery, CS: Coronary sinus.
