[Importance of the angiographic methods of diagnosing left ventricular postinfarct aneurysms in the choice of surgical treatment].

Complete clinical and X-ray examination including catheterization of the heart cavities and selective coronarography was conducted in 116 patients suffering from postinfarction aneurysm of the heart. In 97.4% of cases the aneurysm of the heart was localized in the basin of the anterior interventricular branch of the left coronary artery. The size of the aneurysm was determined by the extent of affection of the coronary channel expresses as an overall value. Particular attention was focused on the study of the functional potentialities of the intact port of the left-ventricular myocardium. It is concluded that it is expedient to perform the operation for aortocoronary shunting to the affected arteries supplying blood to the part of the left-ventricular myocardium which is not involved in the aneurysm, so as to improve the function of the left ventricle after resection of the aneurysm.
