Methods：Data for patients with significant LMCA and triple vessels stenosis who underwent CCAB or OPCAB were collected retrospectively between January 1999 and May 2006. Non-randomized, retrospective data analysis included demo- graphic and preoperative risk factors, operative details, clinical outcome and early follow-up. Results： The number of distal anastomo- sis and grafts varied from 3 to 6. The average number per patient was similar in the two groups （OPCAB group：3.76 ± 0.98, CCAB group：3.81 ± 1.02）. Thirty-day mortality occurred to one patient in the OPCAB group whereas two early deaths were observed in the CCAB group but did not reach statistical significance （P 〉 0.05）. The frequency of atrial fibrillation （AF）, IABP usage, mediastinitis, re-operation for bleeding （or tamponade） were similar in the two groups （P 〉 0.05）. Postoperative inotropic requirements, peak CKMB, ventilation time, blood loss, FFP, RBC transfusion need and the length of ICU-stay were all significantly lower in the OPCAB group compared with CCAB group（P 〈 0.05）.Conclusion： Significant LMCA and triple-vessel stenosis can safely and effectively undergo myocardial revascularization using OPCAB surgery. LMCA should no longer be seen as a contraindication to perform OPCAB grafting.展开更多
