A Simple Technique to Reduce Tension on Coronary Button Anastomosis in Aortic Root Surgery

The permanency of the coronary ostial anastomosis is an important predictor of morbidity in aortic root surgery. We introduced a technique to reduce coronary reimplantation-related complications in aortic surgery. We believe that plicating the folds of the graft at both sides of the coronary ostial anastomosis reduces the tension on the suture line and may be advantageous to avoid pseudoaneurysm formation, detachment of the coronary button from the graft, distortion of the coronary geometry, or bleeding from the suture line.
