Abstract

Myocardial bridging is a congenital coronary anomaly defined as a segment of a major epicardial coronary artery goes intramurally through the myocardium beneath the muscle bridge. In our study we dissected 20 human heart specimens to observe the myocardial bridges over the left anterior descending branch of left coronary artery. Out of 20 specimens the myocardial bridges are located at a distance between 21-30 mm in 14 heart specimens (70%), 31-40 mm distance in 4 heart specimens (20%) and 41-50 mm in 2 heart specimens (10%) were observed. Myocardial bridge has been associated with angina, arrhythmia, depressed left ventricular function, myocardial stunning, and early death after cardiac transplantation, sudden death. The results of the study were compared with other literatures and significance variations are noted.
