冠状动脉心肌桥是一种先天性的冠状动脉发育异常。冠状动脉主干及其主要分支多走行于心外膜下脂肪组织内或心外膜深面,当冠状动脉被心肌覆盖,在心肌内走行时,形成心肌桥。被心肌覆盖的冠状动脉段称为壁冠状动脉,覆盖在冠状动脉上的心肌称为心肌桥[1]。目前认为冠状动脉心肌桥的 Coronary myocardial bridge is a congenital coronary artery abnormalities. Coronary artery trunk and its main branches and more in subependymal fat tissue or deep epicardium, when the coronary artery is covered by the myocardium, walking in the myocardium, the formation of myocardial bridge. Coronary artery covered by the myocardium is called the wall of coronary artery, covering the coronary artery called myocardial bridge [1]. Currently considered coronary myocardial bridge
