Popis: | To the Editor: An intramural coronary artery is defined as an arterial segment of variable length that, instead of lying subepicardially, courses deep in the myocardium and is covered by myocardial fibers (a “myocardial bridge”).1 On an angiogram, it may be marked by systolic compression with luminal narrowing. Although its pathophysiologic importance remains controversial, it has been shown that persistence of coronary-artery compression into diastole, when the largest fraction of coronary blood flow takes place, impairs myocardial perfusion.2 The recent study by Yetman et al.3 provided strong evidence that myocardial bridging is an important cause of myocardial ischemia in children . . . |
