摘要
Myocardial bridge （MB） is regarded as a common .anatomic variant rather than a congenital conditionanomaly, defined as the intrainyocardial course of a portion of the coronary artery. It was first mentioned by Rayman in 1737 and first described by Grainicianu in the early 1920s. The current gold standard tor diagnosing MB is coronary angiography with the typical systolic compression of the epicardial coronary vessel （milking effect）.
