Myocardial Bridge: Imaging and Managemenet

Abstract

Myocardial bridge (MB) is an abnormality in which a coronary artery is covered by bands of membranous or muscular myocardium instead of running on epicardium, causing compression of the affected artery and leading to stenosis (and severe stenosis in the contractile phase). As the lumen of the artery is reduced, blood flow to the myocardium is reduced, increasing the chances of ischemic events. The most common artery involved is the left anterior descending (LAD) artery, the middle segment being the most commonly affected location.
