Myocardial bridging – Sudden unexpected death of a young girl

Abstract

Myocardial bridging (MB) is a relatively uncommon congenital anomaly where a segment of the coronary artery dips inside the myocardium and takes a tunneled course under a bridge of the myocardium. This leads to the compression of the coronary artery during systole resulting in hemodynamic changes and their clinical manifestations. However, it is an incidental finding but can present with multiple complications like myocardial ischemia, infarction, and sudden death, primarily when associated with other risk factors like left ventricular hypertrophy of the heart. Therefore, a careful examination of the heart is essential for evaluating the clinical significance of the MB. Here, we presented a case of a 30-year-old young female who had a sudden death, and her histological examination of the heart showed MB of left anterior descending coronary artery (LAD).
