Overview

A myocardial bridge or MB is defined as a segment of a major coronary epicardial artery that "tunnels" or passes intramurally through the myocardium beneath the muscle bridge during systole.[1][2] Myocardial bridges are generally located in the distribution of the left anterior descending artery (LAD) and its diagonal branches. Systolic narrowing of the epicardial artery shows complete reversal during diasole.[1] The angiographic manifestation depends on: the thickness and length of myocardial bridge, the reciprocal orientation of the coronary artery and myocardial fibers, the presence of loose connective tissue or adipose tissue around the bridged segment, the presence of an aortic outflow tract obstruction, the intrinsic tone of the wall of the coronary artery, the presence of a proximal coronary fixed obstruction and the state of myocardial contractility.[1]

Example

Shown below is an animated image depicting myocardial bridge.

Myocardial bridging


Shown below are two static images of the same case depicting myocardial bridge. Outlined with yellow in the image on the left is the part of the coronary artery during diastole. This same part of the coronary artery is outlined in yellow in the image on the right during systole; note that this outlined part is narrowed compared to its shape during diastole. Shape of the coronary artery during diastole The coronary artery is narrowed during systole which is consistent myocardial bridging.
