- Abstract
- Objectives. Coronary artery bypass grafting (CABG) using bilateral internal thoracic artery (BITA) has been proven to improve survival. Many surgeons use the composite Y-graft which is made of left ITA (LITA) and right ITA (RITA) grafts. The LITA is typically anastomosed to left anterior descending artery (LAD). However, we have used RITA for LAD instead of LITA and reviewed the patency of ITA grafts and their clinical outcomes. Methods. We analyzed 48 patients who underwent CABG using a BITA composite Y-graft from 2002 to 2012. In 30, LITA was anastomosed to LAD (Group L). The other 18 had RITA to LAD anastomosis (Group R). Results. The mean age of Group R was higher than that of Group L (p = 0.009). Postoperative angiography was performed in 35 patients (73%). Two patients in Group L and none of the patients in Group R had an ITA graft failure. The incidence of ITA graft failure and new adverse cardiovascular events were not different between the two groups. Conclusion. The clinical outcome of RITA to LAD anastomosis is comparable with anastomosis of LITA to LAD in CABG using BITA composite Y-grafts. This technique may be useful when longer and larger ITA grafts are needed.
