[Coronary artery bypass grafting under the beating heart in a patient with insufficient cardiopulmonary bypass].
Coronary artery bypass grafting in a 64-year-old male with a severe calcified ascending aorta was performed under the beating heart, because of insufficient cardiopulmonary bypass. The patient suffered inferior and anterolateral myocardial infarction with moderate mitral regurgitation. Computerized tomography showed a severely calcified ascending aorta. During the operation, cardiopulmonary bypass was conducted with femoral arterial cannulation and bicaval cannulation. Adequate perfusion flow, however, could not be achieved. Anastomoses of left internal thoracic artery-left anterior descending artery and right gastroepiploic artery-right coronary artery were performed under a beating heart supported by cardiopulmonary bypass. The patient made an uneventful recovery and postoperative angiography revealed patent grafts. Mitral regurgitation remained unchanged, but the postoperative lifestyle has been stable for the last 15 months.
