Two cases of minimally invasive reoperative coronary artery bypass

Reoperative coronary artery bypass grafting (CABG) are still associated with higher mortality than primary CABG. This is due in part to the potential for cardiac and patent graft injury during their dissection and the reopening of the sternum. Therefore, in two patients with recurrent angina attributable to occlusion of the old vein graft to the LAD, we performed reoperative CABG by the minimally invasive direct coronary artery bypass (MIDCAB) procedures. The left internal thoracic artery was anastomosed to the LAD through small anterolateral thoracotomy without cardiopulmonary bypass. Both patients recovered fast and underwent postoperative angiogram, showing the new grafts widely patent. About two weeks later, both discharged in the conditions of nearly normal activities. The reoperative MIDCAB grafting might be expected to be as safe and promising as the primary one.
