Challenges in Evaluation and Management of Children with Myocardial Bridging

Abstract

Myocardial bridging (MB) is a congenital anomaly where a coronary artery branch or group of branches extends inside a tunnel consisting of myocardium. Although it is mostly considered “benign,” it is reported that MB may lead to significant cardiac problems and sudden cardiac deaths. While it is a congenital anomaly, its symptoms usually arise at further ages rather than childhood. The literature on MB in children is in the form of case reports or small case series. This is why pediatric cases are assessed in the light of information obtained from adults. This review compiled the literature on MB in adults and children and compared it, as well as discussing questions arising regarding the clinic, diagnosis, and treatment of MB.

A Case of Syncope in a Child due to the Large Segment of Myocardial Bridge

“…The treatment of symptomatic patients with myocardial bridging mainly includes medication. 2) The β-blockers are capable of reducing systemic and intramural pressures and thereby the external vessel compression. Meanwhile, the β-blockers could prolong diastole and improve coronary perfusion.…”

“…The myocardial bridging may cause unexplained chest distress and sudden death in children. 2) To our knowledge, there was not reported child case of myocardial bridge involving the large segment of the LAD, CX, and RCA at the same time. Here we report on this rare case.…”
