Unroofing of myocardial bridge

Myocardial bridge is a segment of coronary artery which has an intramyocardial course. It is mostly considered as an incidental finding and is often asymptomatic. Angiographic incidence of myocardial bridge may vary from 0.5% to 16% in different series. Myocardial bridges may be associated with angina, myocardial infarction, and rarely sudden cardiac death. Though most myocardial bridges are left alone, some have been stented and yet others bypassed. But stent fractures have been reported in myocardial bridges.
