摘要

Myocardial bridging is a congenital coronary anomaly with a variety of clinical manifestations. Traditionally, myocardial bridging has been considered a benign condition, but some cases of myocardial ischemia, infarction and sudden cardiac death due to myocardial bridging have been reported. Various studies have suggested that in their intramyocardial segments, these vessels are protected from obstructive atherosclerosis, with atherosclerosis being present in the proximal part of the artery. We report a case in a 45-year-old male who had a 2.5-cm long myocardial bridging over the left anterior descending artery, with obstructive atherosclerosis being present in the proximal as well as the intramyocardial part (part of the artery below the myocardial bridge). Atherosclerosis occurring in the intramyocardial segment is a rare occurrence, and combined with systolic narrowing by the myocardial bridge can lead to ischemia of the cardiac musculature.
