Abstract:
Objective To evaluate the results of a modified linear plieatinn of left ventricular aneurysms during off-pump coro- nary artery bypass surgery,Methods From January 2001 to June 2006,206 patients were operated on for nonruptured postinfarefion left ventrieular aneurysm during off-pump coronary artery bypass surgery.Repair was completed on the beating heart to minimize isch- emia and allowed assessment of wall function and viability.All patients presented with symptoms of angina and congestive heart failure or ventricular arrhythmia.The NYHA functional class of the patients ranged from grade 1]to grade IV.Preoperative ejection fraction and left ventricular end-diastolic diameter were 0.41?0.06 and(57.4?6.8)mm.The ventricular preoperative and postoperative performances were compared.Results Hospital mortality was 0.5 %(1/206).Coronary artery bypass was performed with an average of 2.9?0.9 grafts per patient.At the time of follow-up,all the patients had no symptoms.The mean NYHA class and ejection frac- tion increased significantly(P
