Background. "Off-pump" coronary artery bypass grafting (OPCABG) became more popular in recent years for its potential advantages of reducting perioperative morbidity related to cardiopulmonary bypass (CPB). We retrospectively analyzed the early results of multivessel OPCABG to compare them with conventional CABG under CPB. Methods. From April 2000 to Oct 2000, 15 patients received multivessel OPCABG (group A). CTS or Octopus II stabilizer was used with coronary anastomosis. "Auto-perfusion system" was used at late stage of our series for myocardial protection in the procedure. At the same time, patients who received primary isolated CABG under CPB were compared as control (group B). Results. There was no operative mortality or major morbidity in the group of multivessel OPCABG. Two patients who failed multivessel OPCABG due to hemodynamics compromise were converted to conventional CABG under CPB uneventfully. The amount of operative blood loss and donor blood transfusion, the duration of postoperative mechanical ventilation support, the mean intensive care unit stay and postoperative hospital stay were less in group A. Conclusions. Multivessel OPCABG is feasible in surgical techniques in selected patient. It is associated with minimal operative mortality and morbidity partly because of obviating the adverse effect of CPB. Prospective study with long-term follow-up is needed to better define the role of OPCABG.
