Coronary Artery Anastomosis

: It is well known that proximal part of a sequential bypass grafting often demonstrates better patency than distal part does due to more favorable hemodynamics of side-to-side anastomosis. Therefore, we adopt side-to-side anastomosis( parallel fashion) even for most distal part of bypass grafting. In addition to superiority in hemodynamics, side-to-side anastomosis (parallel fashion) provides a couple of advantages such as ① easiness in creating a very long opening of the anastomosis, ② compatibility in size (diameter) mismatch between graft conduit and coronary artery, and ③ excellent hemostasis from the suture line. This article describes technical details and tips of side-to-side anastomosis in both parallel fashion and diamond( cross direction) fashion.
