Detailed explanation-1: -A myocardial bridge (MB) is a congenital heart defect in which one of the coronary arteries tunnels through the heart muscle itself (myocardium).
Detailed explanation-2: -divided the myocardial bridging into two types: superficial and deep muscle types. The former does not constrict the coronary flow during systole; whereas the latter may compress the coronary artery, reduce the flow and induce myocardial ischemia.
Detailed explanation-3: -Myocardial bridging (MB) occurs when an epicardial segment of the coronary artery [usually the left anterior descending (LAD) artery] goes intramyocardially, causing chest pain due to systolic compression [1]. MB was first discovered at an autopsy in 1737 and was first described by angiography by Porstmann et al.
