Abstract

Coronary artery surgery has developed during a fundamental shift in emphasis away from coronary artery perfusion in its various modes towards cold cardioplegic arrest in which the myocardium is ischemic allowing a still, bloodless operating field, yet protected from the effects of ischemia by reduction of its metabolism to a minimum by coronary infusion of cold chemical cardioplegic solutions. Alternative techniques for coronary artery surgery had been ventricular fibrillation with the coronary arteries continuously perfused via the aorta, hemostasis at the anastomotic sites being obtained by stitches or obturators, intermittent aortic occlusion during the distal anastomoses with the proximal being performed with a sidebiting aortic clamp, or even with a continuously beating heart in the more accessible areas. Only the second now remains as a regular alternative to cardioplegia, with the great majority of centers — 99% in the United States — preferring cardioplegia.
