Background: Since ”off-pump” coronary artery bypass grafting (OPCAB) has been refined, we try an effort to avoid the adverse effects of cardiopulmonary bypass (CPB) and perform OPCAB in Chinese patients. Methods: Between July 1999 and March 2001, 150 OPCAB were performed through a median sternotomy, using the Octopus II (Medtronic, MI) and deep pericardial suture-traction for stabilization to enable access to all territories of the heart. Emergent cases with cardiogenic shock under inotropics or intra-aortic balloon pump support were excluded. Results: An average of 3.0±0.7 (range 1-6) grafts/patient were done. Complete revascularization was performed in 94.7% of cases. Operative mortality was 2%. There were two cases of conversion to cardiopulmonary bypass, and the utility of internal mammary artery (IMA) was 82.7%. The mean postoperative endotracheal intubation time was 6.8±4.9 hours, length of ICU stay was 1.5±0.7 days. Postoperative length of stay was 9.0±2.8 days. No case of sternal wound infection or acute renal failure occurred in this group of patients. Conclusions: With progressive experience, proper technique, and mechanical stabilization, OPCAB may be used as a safe and effective procedure of myocardial revascularization in Chinese patients.
