Background: We evaluated the outcomes in patients who have undergone total arterial revascularization using the bilateral internal thoracic arteries (BITA) with off-pump and aorta no-touch technique.

Methods: From March 2001 to September 2007, 512 consecutive patients with triple-vessel disease underwent total arterial revascularization with off-pump and aortic no-touch technique, using BITA or the right gastroepiploic artery (RGEA) in addition to BITA. Only BITA grafts were used for bypass to coronary arteries in 353 patients, and additionally in situ RGEA was bypassed to right coronary arteries in 159 patients. The mean number of distal anastomoses was 4.15 ± 0.8 per patient.

Results: One 30-day death occurred. Deep sternal wound infection occurred in 2 patients. The rate of perioperative stroke was 0.8%. The patients were followed for as long as 6 years (mean follow-up, 37.9 ± 17.7 months). The 1-year and 5-year actuarial freedom from cardiac death was 98.3% and 96.7%, respectively. The 1-year and 5-year actuarial freedom from cardiac events was 97.1% and 89.3%, respectively. Using RGEA was a significant predictor of cardiac event–free survival (p = 0.046).

Conclusions: Total arterial revascularization using off-pump coronary bypass and aortic no-touch techniqe with BITA grafts was safe and effective, with low mortality among patients with triple-vessel disease. Patients undergoing in-situ RGEA grafting for right coronary arteries appeared to have fewer cardiac events than did patients undergoing only BITA grafting in triple-vessel disease.
