[State of the coronary circulation in patients with a chronic aneurysm of the heart].

Examination covered 56 patients with chronic post-infarction aneurysm of the heart. It included electro- and phonocariography, selective coronarography and ventriculography of the left heart. In the majority of these patients the affection started with myocardial infarction which gave rise to the development of the cardiac aneurysm. Coronarography disclosed a lesion of the left anterior descending artery in the form of an extended occlusion. Collateral coronary circulation was indefinable. Ventriculography of the left heart disclosed an aneurysm whose localization accorded with electrocardiographic indications. In the development of aneurysms of the heart the authors attach great importance to presence of collateral circulation at the instant of an acute lesion of the coronary artery.
