ABSTRACT
BACKGROUND:
After more than a decade of experience with off-pump coronary bypass surgery, still no consensus exists concerning its benefit on clinical outcome compared to the on-pump technique. In this 12-month follow-up, we compare off-pump and on-pump surgery on the appearance of graft patency, myocardial function, and clinical outcome.METHODS:
One hundred twenty patients were randomized to off-pump or on-pump coronary surgery. Angiography was performed intraoperatively, at 3 and 12 months. Global myocardial function was estimated by magnetic resonance imaging (MRI) preoperatively and 12 months postoperatively, as well as functional class and stress testing.RESULTS:
After 12 months internal mammary artery patency was 94% in the off-pump group and 96% in the on-pump group. Vein graft patency was 80% and 87%, respectively. No statistically significant difference between the two groups existed. There were no differences in exercise capacity improvement and attenuation of symptoms between the groups.CONCLUSIONS:
At 12-months follow-up, off-pump coronary bypass surgery provided the same angiographic graft patency as the on-pump technique. Improvement in functional class and exercise capacity was the same in both groups.
