[Coronarography and ventriculography as a "golden" standard of examining patients with post infarction aneurysms of the left ventricle subjected to surgical treatment].

The character of lesions of the coronary bed and specific features of formation of collateral coronary circulation was studied in patients with post-infarction aneurysms of the left ventricle. Marked atherosclerotic lesion of coronary arteries, especially in the basin of the anterior interventricular artery, was observed in all examined patients with post-infarction aneurysms of the left ventricle (LV). Coronary collateral circulation is absent or formed extremely slightly in cases of multifocal lesion of the coronary arteries. It was found that impairment of the contractile function of the LV myocardium promoted dramatic disturbance of hemodynamics indices in patients with post-infarction aneurysms of the left ventricle.
