An 80-year-old man successfully underwent reoperative coronary artery bypass grafting( CABG) via left thoracotomy without cardiopulmonary bypass. The proximal end of the saphenous vein graft( SVG)was connected to the thoracic aorta using an automated proximal anastomosis system. Then the SVG routed beneath the pulmonary hilum was anastomosed to the high lateral branch and the anterior descending artery in a sequential mode. He recovered uneventfully and is free of chest pain after redo CABG. In selected patients, redo CABG for the left coronary artery can be safely performed through left thoracotomy.
