Endoscopic Mitral Valve Repair in a Patient With Persistent Left Superior Vena Cava Draining Into the Coronary Sinus - Cannulation Technique and Surgical Management.

Persistence of the left superior vena cava is often an incidental finding during cardiac surgical procedures. In minimally invasive valvular surgery, it may jeopardise venous drainage and myocardial protection. This How-To-Do-It paper describes the cannulation strategy in a case of minimally invasive mitral surgery in a patient with persistence of the left superior vena cava and absence of the anonymous vein detected with preoperative multimodality imaging.
