[Experience in the perfecting of direct myocardial revascularization inpatients with ischemic heart disease].

The first 100 operations for aortocoronary and mammary-coronary shunting in patients with ischemic heart disease are analysed. The operations were carried out on patients aged from 36 to 59 years who had no severe concomitant diseases. Angina pectoris of effort was encountered in 47%, angina of effort and of rest in 33%, and unstable angina in 20% of patients. The operations were performed under conditions of extracorporeal circulation. In 100 patients 184 arteries were shunted (1.8 shunt per one patient). A mammary-coronary shunt was established in 13 patients; the left internal thoracic artery was used in all of them for shunting the anterior interventricular branch. Improvement was recorded in 88.5% of patients after the operation. Thirteen (13.0%) patients died. It is concluded that patients should be chosen with great care for aortocoronary shunting with due regard for the risk factors.
