BACKGROUND: Early and 1-year results of arterial Y composite grafts anastomosed to the in situ left internal thoracic artery were studied. METHODS: Three hundred twelve patients who underwent off-pump coronary artery bypass using arterial Y composite grafts for revascularization of the left coronary artery territory were analyzed. A skeletonized right internal thoracic artery (RITA) or right gastroepiploic artery (RGEA) was anastomosed to the side of the left internal thoracic artery to construct a Y composite graft. Propensity-matched analysis was used to match patients using RITA (RITA group, n = 102) with patients using RGEA (RGEA group, n = 102). Postoperative coronary angiographies were performed early (200 of 204; 1.8 +/- 1.7 days) and 1 year (171 of 204, 11.3 +/- 2.5 months) postoperatively. RESULTS: There were no differences in postoperative mortalities (1 of 102 versus 2 of 102; p = 1.000) and morbidities including atrial fibrillation, mediastinitis, and perioperative myocardial infarction between the RITA and RGEA groups (not significant). Early and 1-year postoperative angiographies showed that there were no significant differences in patency rate between the two groups (early, 99.4% versus 99.3%; p = 1.000; 1-year, 95.4% versus 97.4%; p = 0.251). When the early and 1-year patency rates were compared based on the side-arm graft used, there were no differences in patency rates of RITA versus RGEA grafts between the two groups (early, 99.4% versus 100%; p = 1.000; 1-year, 96.5% versus 97.7%; p = 0.724). CONCLUSIONS: Construction of Y composite grafts using the RITA or RGEA showed comparable results including patency rates early and 1 year postoperatively.
