"Webb31 maj 2024 · Myocardial bridges are congenital abnormalities where a segment of coronary artery travels intramyocardially, rather than the typical epicardial course. The overlying segment of muscle is termed the “myocardial bridge”. The commonest vessel involved is the left anterior descending (LAD) artery [ 1 ]. " - Nitrates and myocardial bridging
