Objectives: It is unclear whether the additional bypass technique to supplement Bilateral Internal Artery grafting (BITA) influences the patient outcome in coronary surgery. We analyzed the impact on late survival after BITA of sequential ITA grafts use on the left side and of the third associated conduit on the right side.
Methods: From 1989 to 2014, 2,477 patients underwent BITA surgery. The revascularization of the left side was optimized with a sequential ITA graft in 1,144 patients. The revascularization of the right side was performed with an associated vein graft in 599 patients and with an associated Gastroepiploic graft (GEA) in 833 patients; it was not indicated or not accessible in 1,045 patients. The primary end point was overall mortality from any cause. The mean postoperative follow-up was 13.3 ± 7.1 years and 94% complete.
Results: The population was not homogenous: greater the arterial revascularization, lower the risk profile. The 30-day mortality was 1.4% without influence of the surgical technique performed. Late mortality was significantly influenced by age, heart failure, LV ejection fraction and diabetes. In multivariate analysis with Cox model (Chi-square 624.949, df11, p=0.001), the use sequential ITA graft was the only technical significant independent prognosis factor of survival, predominant over complete revascularization. The revascularization of the right side (GEA, vein, or no graft) had no influence on long-term survival.
Conclusion: These results confirm that higher the number of ITA anastomoses, better the longterm survival. It is a strong support of the extensive use of arterial grafting with multiple ITA bypass.
