Left ventricular aneurysm subsequent to cleavage of myocardial bridging of a coronary artery.
In two patients, an aneurysm of the left anterior wall developed at the site of periarterial muscle resection of a myocardial bridge over the proximal portion of the left anterior descending coronary artery. One patient had a severe atherosclerotic stenosis proximal to the bridge. He also received a bypass graft to the left anterior descending coronary artery distal to the bridge. In the other patient without signs of atherosclerotic disease, only cleavage of the myocardial bridge was performed. Observations in these two cases suggest the need to reevaluate the risks of surgical treatment in symptomatic patients with myocardial bridging.
