Through the Lens of Uniqueness: An Atypical Presentation of Myocardial Bridge in the Coronary Trifurcation

Abstract

Myocardial bridges are commonly encountered findings during coronary angiography, typically occurring over the mid or distal segments of the left anterior descending artery (LAD). Coronary trifurcation represents another variant of normal coronary anatomy. However, muscle bridges rarely involve a trifurcation branch. Symptomatic patients with muscle bridges often present with angina or dyspnea and may even experience acute coronary syndromes. Management typically involves medical intervention, with percutaneous coronary intervention (PCI) or cardiac surgery reserved for severe cases. Here, we present a unique case of a young female who presented with acute coronary syndrome due to a muscle bridge occurring over a trifurcation branch.
