A Case withWrong Anastomosis of Left Internal Mammary Artery to Great Cardiac Vein

Visually distinguishing artery from vein during coronary artery bypass grafting (CABG) can be occasionally challenging and may result in errors in anastomosis. We report an unusual case of on-pump CABG surgery in which the left internal mammary artery (LIMA) was anastomosed to an epicardial vein instead of the left anterior descending (LAD) coronary artery erroneously (Iranian Heart Journal 2009; 10 (2):31-33).
