冠状动脉搭桥术采用自体静脉（隐静脉）。其中最粗的移植血管向下经过心脏的中心直到与冠脉的左前降支汇合，另一支位于冠脉旋支右方的移植血管呈“Y”形延伸。
This patient underwent coronary artery bypass grafting with autogenous vein (saphenous vein) grafts. The largest of these runs down the center of the heart to anastomose with the left anterior descending artery distally. Another graft extends in a "Y" fashion just to the right of this to branches of the circumflex artery. A white temporary pacing wire extends from the mid left surface.
