Myocardial Ischemia by Aggravation of Myocardial Bridging

ABSTRACT
Myocardial bridging (MB) occurs when the myocardium covers a segment of a major epicardial coronary artery, resulting in a tunneled arterial segment. Although MB is generally considered benign, it has been associated with myocardial ischemia. A 70-year-old man with MB (50% luminal narrowing during systole) at the mid-left anterior descending artery (LAD) on previous coronary angiography (CAG) visited our hospital with worsening chest pain. His blood pressure (BP) was not well controlled because of poor compliance. Follow-up CAG showed that MB at the mid-LAD progressed to severe stenosis (>90% luminal narrowing during systole) and the total length of tunneled artery extended from 22.5 to 23.9 mm. His chest pain was relieved by BP control. This is the first report of myocardial ischemia secondary to progression of MB demonstrated by CAG in Korea.
