Abstract
A survey of techniques used in human coronary artery bypass graft (CABG) surgery by 400 experienced cardiac surgeons was presented. These surgeons performed 41,000 CABG operations in 1975. A 70-question survey form was answered by each surgeon on their techniques for cardiopulmonary bypass and myocardial preservation, choice of bypass conduit and grafting techniques. Extracorporeal circulation was almost always used in CABG survey. A wide divergence of practice exists in the use of left ventricular vents and in methods of myocardial protection during coronary artery grafting. A spectrum of graft suture techniques was employed, the most common being a running double-ended suture anastomosis with the end of the vein initially fixed only at its heel to the coronary artery. Only 23 surgeons (6%) preferred the internal mammary artery (IMA) rather than saphenous vein, when feasible, as the bypass conduit of choice for CABG surgery.
