Core Tip
Core tip: Myocardial bridging (MB), an anomaly in which the myocardium overlies the intramural course of segments of the epicardial coronary arteries, is associated with cardiac events. This may be explained by myocardial ischemia, coronary spasms, and/or mechanical compression of the coronary artery by the MB itself. We encountered a patient with angina pectoris both at rest and during exercise, which was caused by both coronary spasm and MB-induced direct myocardial ischemia. The latter finding was revealed using a pressure wire. MB sometimes causes two vascular characteristics, coronary spasms and direct myocardial ischemia, whose management is quite different.
