Abstract

The coronary arteries are epicardial but in myocardial bridging a segment of the coronary artery take a “tunneled” intramuscular course under a “bridge” of overlying myocardium. Myocardial bridge affects left anterior descending (LAD) artery most commonly and occurs in 67–98% cases. The middle segment of LAD is most frequently affected. Other arteries such as diagonal (18%) and marginal (40%) branches may also be involved. One of the initial angiographic imaging of myocardial bridge was described by Portsmann in 1960. Prevalence rates of myocardial bridging differ based on the mode of evaluation. This chapter covers the pathophysiology of ischemia, clinical presentation, diagnostic testing, special patient populations, prognosis, and treatment.
