This article necessarily deals exclusively with vein and artery bypass grafts. The venous autograft remains the most versatile operation and data thus far compiled verify its reliability. We advocate normotensive, normothermic perfusion and recommend the interrupted suture technique for most anastomoses. Our guidelines for IMA grafting indicate its applicability for most anterolateral wall vessels, except for unstable emergency patients and those with a large left ventricular mass. We emphasize that the technical details are far more important than the steps involved in coronary artery operations. The operative techniques described and discussed herein are deceptively simple, and direct coronary artery surgery often appears uncomplicated to the inexperienced observerer. However, one should not attempt myocardial revascularization without the benefit of high quality cinecoronary arteriograms. An organized and experienced operative team is mandatory and, above all, the procedure itself must not be an endurance contest between surgeon and patient. Expeditious revascularization produces less morbidity and better overall results.
