technology, the myocardial bridge appears as a “half-moon”-like area that compresses the tunneled coronary artery during systole.9 Nowadays, MB is routinely diagnosed by coronary computed tomographic angiography, where the prevalence of this coronary anomaly ranges from 14% to 35%.10 Here, the myocardial bridge is seen as a shift of a

MYOCARDIAL BRIDGING. Executive Summary . A myocardial bridge (MB) is a segment of an epicardial coronary artery traveling through the myocardium, creating a “bridge” across the artery. MB is a benign congenital anomaly. However, it can be associ-ated with acute coronary symptoms, coronary spasms, ventricular septal rupture, arrhythmias

Original Article Myocardial Bridging: Therapeutic and Clinical Development
The myocardial bridge (MB) is a congenital anomaly of the coronary arteries that usually affect the left anterior descending artery (ADA), when one or more myocardial bundles cross or involve a segment of the epicardial coronary artery, which crosses the intramural portion of the myocardium, below the muscular bridge.

Our results show that regardless of the existence of the myocardial bridge in 70% of cases, there was no evidence of a coronary atherosclerotic disease on the descending branch of the left coronary artery.

Myocardial bridging constitutes a congenital, usually benign, coronary abnormality defined as a segment of a major epicardial coronary artery that follows an intramural course through the myocardium. On the basis of clin-ical and histopathological data, myocardial bridges appear to be spared from atherosclerosis.
