Abstract:Background Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (CPB) is gaining popularity as an effective alternative to conventional CABG using cardiopulmonary bypass. With the advent of mechanical tissue stabilization systems and intra coronary shunts the technique of off-pump CABG (OPCAB) is now applicable to revascularize the patients with multi-vessel disease. Methods A total of 293 patients underwent surgical myocardial revascularization without cardiopulmonary bypass between July 1996 and October 2000 at our hospital. Of these, 245 patients received 2 or more grafts: two in 193 patients, 3 in 46 patients and 4 in 7 patients. A mechnical tissue stabilization system (CTS or Octopus II/III) was used in all patients. In majority of the patients intra coronary shunts were also used. A total of 550 distal anastomoses were made and the vessels grafted were LAD (n=245), diagonal (n=90), ramus intermedius (n=16), obtuse marginal branches (n=58), distal right coronary artery (n=88) and posterior descending artery (n=52). Results There was no incidence of perioperative myocardial infarction. Three patients had transient ST segment elevation postoperatively which was normalized in the first few hours. Hospital mortality was 0.4%. No patient needed reexploration for bleeding. No patient had neurological event or pulmonary problems. All these patients except one were discharged from the hospital between 6 and 9 days. Conclusion In selected patients multi vessel OPCAB is a safe and reproducible technique and the mechanical tissue stabilization systems have made the procedure less difficult to perform. Its usefulness is more pronounced in high risk patients with comorbidities and the patients who undergo this procedure are free from major complications.
