Background: Off-pump coronary artery bypass (OPCABG) grafting has emerged as an effective alternative technique for allowing coronary revascularization without the use of cardiopulmonary bypass. OPCABG has been associated with decreased postoperative morbidity, shorter hospital stay, reduced cost, and reduced operative mortality in some studies. Materials and Methods: A total of 190 patients who underwent isolated coronary artery bypass graft surgery were evaluated with the European System for Cardiac Operative Risk Evaluation (EuroSCORE) risk scoring system. Moreover, we also compared the discriminatory potentials between the EuroSCORE II with <5 and >5 scores. Results: EuroSCORE high-risk patients showed higher rates of blood transfusion (66.9%), intraaortic balloon pump insertion (12.6%), atrial fibrillation (21%), and renal failure (46.8%). There was one mortality in each EuroSCORE group. Conclusion: OPCABG can be accomplished safely in selected high-risk patients with acceptable morbidity and mortality without compromising complete revascularization. Severe renal failure needing dialysis, stroke, and deep sternal wound infection in the postoperative period carries high morbidity and mortality after OPCABG. There is no ideal risk prediction model for an individual patient but multidisciplinary approach and individual patient factors determine the operative risk.
