Is There a Protective Effect of Sequential Grafting in Coronary Bypass Surgery Using Bilateral Internal Thoracic Artery?

From 1989 to 2014, 1644 patients underwent BITA surgery without any additional arterial graft. The revascularization of the left side was optimized with a sequential ITA graft in 824 patients. The revascularization of the right side was performed with an associated vein graft in 599 patients. Propensity score was calculated by logistic regression model and patients were matched 1 to 1 leading to two groups of 334 matched patients. The primary end point was overall mortality from any cause.
