[Percutaneous occlusion of a left superior vena cava draining into the left atrium: two case reports]. / Occlusion percutanée d'une veine cave supérieure gauche s'abouchant à l'oreillette gauche. A propos de deux observations.

ABSTRACT

Persistent left superior caval vein draining into the left atrium is responsible for a right-to-left shunt which can be source of desaturation and systemic embolism. We present 2 cases of successful percutaneous treatment in 2 patients in whom no bridging vein existed and systemic desaturation was found after repair of the underlying congenital heart.
