Multiple myocardial bridges associated with left‐ventricular dysfunction, intermittent left bundle branch block, and cardiac memory: A case report

Myocardial bridges are a congenital anomaly in which a segment of the coronary artery takes a “tunneled” intramuscular course. Few reports have associated myocardial bridges with left‐ventricular dysfunction in patients with ischemia. Intermittent left bundle branch block is a conduction disturbance that has been described to be associated with myocardial bridges and cardiac memory. This study reports unusual associations of multiple myocardial bridges, angina, left‐ventricular dysfunction, intermittent left bundle branch block, and cardiac memory.
