Cardiac arrest and myocardial bridging

Abstract

Myocardial bridging, a systolic compression of an intramyocardial segment of an epicardial coronary artery, may be an incidental finding during coronary angiography or autopsy. However, some investigators reported a variety of acute coronary syndromes associated with this condition. We describe the case of a relatively young male patient (43 years old) referred to our emergency department for cardiac arrest and subsequent evidence of significant myocardial bridging at coronary angiography. The patient has been treated with an implantable cardioverter-defibrillator to prevent possible subsequent arrhythmic events associated with the myocardial bridging.
