Abstract
Revascularization of the ischemic heart is feasible in selected cases of coronary artery disease by implantation of the internal mammary artery into the myocardium. Of the first 78 patients undergoing Vineberg's operation at the Cleveland Clinic Hospital, 75 are alive. In 80 per cent a patent implant has been demonstrated. Direct communication between the implant and the coronary artery distal to the original obstruction is demonstrable by internal mammary arteriography.
