冠状动脉心肌桥的研究进展

摘要

Coronary artery myocardial bridging is defined as a segment of coronary or a section of its branches that goes in the subepicardial myocardial layer. Coronary anatomy of this congenital anomaly can cause myocardial ischemia, myocardial infarction, or even sudden death. Here is to present the anatomical characteristics of myocardial bridging,the occurrence mechanism of atherosclerosis, the characteristics of in-travascular ultrasound, diagnostic value of CT coronary angiography, and the related problems in the treatment and so on.%冠状动脉心肌桥是指冠状动脉某一段或其分支的某一段走行于心外膜下的心肌层内.这种先天性的冠状动脉解剖异常可以引起心肌缺血、心肌梗死,甚至猝死.现对冠状动脉心肌桥的解剖学特点、发生动脉粥样硬化的机制、血管内超声的特征、CT冠状动脉造影的诊断价值及治疗上需要注意的问题等方面进行阐述.
