Myocardial bridging is systolic compression of an epicardial coronary arterial segment by overlying myocardium. It is a rare coronary anomaly, which is generally considered to be benign. It has been suggested that myocardial ischaemia may be seen. In this article, a case of myocardial infarction caused by myocardial bridging is presented.
