Background: In this study, perioperative characteristics of the patients in whom complete off-pump revascularization was performed were investigated, and short term angiographic results concerning the grafts used in the operations were determined by revealing the causes of initial morbidity and mortality. Methods: Between December 2002 and May 2004, 89 patients (81 males, 8 females; mean age 59.7±9.2 years; range 40 to 79 years) who had complete revascularization operation on the beating heart because of multiple vessel lesions and who were operated on by the same operating team were included in our study. Those patients who didn‘t have complete revascularization in the same period were not included in the study. General anesthesia was performed in all patients by means of intravenous narcotic anesthesia. In all patients, target vessel revascularization was started by giving priority to the systems supplying the left ventricule. Following revascularization of the left system, dominant coronary artery system was given priority. A total of 43 control angiographies were performed. Results: The best patency rate was 100% and it was observed in left internal mammarian artery. Bilateral internal mammary artery grafts for left anterior descending territory had also 100% patency. The best patency rate for radial artery was observed by using radial artery to circumfleks territory. The patency rates of saphenous vein grafts was lower than any other arterial graft. Conclusion: Complete revascularization using arterial grafts on the beating heart can be performed succesfully.
