We present an uncommon and underreported complication of coronary artery bypass graft surgery: erroneous anastomosis of the left internal mammary artery to the great cardiac vein. The iatrogenic aorto-coronary arteriovenous fistula with left-to-right shunting resulted in dilation of the coronary sinus, a supporting secondary finding. Factors predisposing to this inadvertent anastomosis include an intramyocardial segment of the left anterior descending coronary artery, demonstrated in this case, as well as epicardial fat and potentially fibrosis of the underlying myocardium.

The article presents a technique of performing coronary bypass operations on the beating heart used by the authors in 847 patients which is based on high thoracic epidural anesthesia, primary formation of proximal anastomoses of the aorto-coronary bypasses and specified succession of the formation of distal, stabilization of the local part of the heart in the field of placing distal anastomosis and access to the lateral and posterior surface of the heart with vacuum stabilizers, using blower-humidifier and intracoronary shunts.

It was found that surgical treatment resulted in the improvement of subjective symptoms of angina and increased contractile reserve of the myocardium during the first days after surgery. Significantly increased subjective and objective exercise tolerance, improvement of local myocardial contractility, diastolic function and symptoms of myocardial remodeling were registered only within 6 months after surgery.

Direct dependence of amplitude of contraction on size of fraction of of blood emission on Teyholts is revealed. It means, that strips of right auriculum myocardium reflect contractility of a left ventriculum myocardium.

The reperfusion damages of heart were manifested by MPTP activation and MF release. The rising of MF level during a cardioplegia is comparable to level, which has been noted at patients with angina before operation of aorto-coronary shunting.
