[Function of the myocardium after revascularization and the patency of coronary shunts].
The article analyzes the contractive function of the myocardium in 149 patients after operation of a single aortocoronary shunt (25 patients), mammaro-coronary shunts with mechanical anastomosis (109 patients) and with manual distal anastomosis (15 patients). Patency of the aorto-coronary shunts was 72%, mammaro-coronary shunts with direct distal anastomosis - 83.5%, with the end-to-side anastomosis - 88.8%. The myocardium function was improved in patients with patent shunts. In patients with incompetent shunts further deterioration of the contractive function of the left ventricle myocardium was noted. It was pointed out that the development of myocardium infarction in the zone of the coronary artery operated upon is not always accounted for by a shunt thrombosis.
