Aneurysm of left ventricle at non-atherosclerosis lesion of coronary arteries

Background/Introduction Aneurysm of left ventricle (ALV) is formed in each 5th patient with acute myocardial infarction in the presence of complete occlusion of the coronary artery (CA) by atherosclerotic plaque. But we noticed the formation of ALV in the absence of atherosclerotic stenosis, for patients with myocardial “bridges” (MB). The essence of this anomaly is the presence of systolic compression of the tunneled segment of the artery, which in itself raises doubts about its clinical significance. Due to the attitude of the medical community toward the MB, as a result of its ambiguous nature, and given the favorable long term trend, the MB is regarded as a variant of the norm. At the same time, increasing reports of cases of sudden death and myocardial infarction associated with the presence of MB demonstrates the relevance of this anomaly.
