Myocardial perfusion occurs primarily in diastole since systolic contraction transiently impedes coronary blood flow especially to the subendocardium. Thus, myocardial bridges replicate the normal microvascular physiology of high diastolic and low systolic flow, albeit at the level of the epicardial
