[Intramyocardial bridges: anatomo-pathological characteristics, diagnosis, and therapeutic strategies].

Intramyocardial bridge is defined as the segment of a major epicardial coronary artery that runs within the cardiac muscle wall (coronary tunneling). Usually, this kind of anatomic variant is asymptomatic but sometimes it may lead to acute coronary syndrome and/or arrhythmias, and more rarely to sudden cardiac death. Treatment for symptomatic patients is pharmacological, using beta-blockers.
