[Coronary bed in aneurysm of the left ventricle].
Clinical and radiologic examination, including selective coronarography and catheterization of the cardiac cavities, was carried out in 110 patients with post-infarction aneurysm of the left ventricle. Three groups of patients were distinguished: patients with affection of one of the major cardiac arteries (44), those with affection of two coronary arteries (32) and patients with affection of three arteries (32). Two patients had no stenosis of the coronary arteries, The anterior interventricular artery was occluded in 95,8% of patients. Operation for aorticocoronary shunt to the artery in the zone of which the arteries were located proved impossible in 65% of patients. Other arteries with no aneurysms in their channels contribute to the formation of collateral circulation and form a network of anastomoses at the boundary with the heart aneurysm and in this improve the nutrition of the healthy part of the myocardium experiencing an additional load. In stenosis of these arteries, the creation of an aorticocoronary shunt is expedient.
