Objective: Diffuse coronary artery disease makes cardiac surgeons hesitant regarding whether coronary artery bypass grafting (CABG) surgery is feasible or not. Coronary artery reconstruction using the internal thoracic artery (ITA) allows bypassing of coronary arteries with diffuse atheromatous plaques without systematically resorting to endarterectomy. The aim of the present study was to evaluate the medium-term results of coronary artery reconstruction. Methods: All patients undergoing coronary artery reconstruction using the ITA between 1999 and 2002 (233 patients) were included in the study. The mean age was 61.9 ± 9.8 years. Two hundred and eighty-one coronary artery reconstructions using the ITA were performed (mean length 3.6 ± 2 cm) for 514 CABGs. Coronary artery reconstruction using the ITA was associated with endarterectomy in 48 cases (17%). Results: In-hospital mortality was 2.6%. Follow-up data were compiled in December 2008. Mean follow-up was 73.4 ± 16.7 months. The actuarial survival rate at 7 years was 89.3 ± 2.1%, and 88% of patients were free of major cardiac events at 7 years. Conclusions: Coronary artery reconstruction gives comparable medium-term results to conventional coronary surgery, even though it is indicated for patients with more severe lesions.
