myocardial bridge

my·o·car·di·al bridge

a bridge of cardiac muscle fibers extending over the epicardial aspect of a coronary artery; this finding, in cases of sudden unexpected death, has led to speculation that cardiac contraction during exertion could constrict the coronary artery.

INTRODUCTION: Muscle overlying one segment of an epicardial coronary artery, first mentioned by Reyman in 1737[1] and Black in 1805,R3]is termed a myocardial bridge and the artery running within the myocardium is called a tunnelled artery.
Bundles of myocardial fibres, which in the form of small bridges, pass over the corresponding part of the coronary artery ("tunnel" segment), are marked as the myocardial bridge [1].
