Unveiling the Rarity: An Anomaly of the Left Circumflex Artery Supplying Left Ventricular Apex and Presenting With Myocardial Infarction.

Coronary arteries are typically identified based on the myocardial territory they supply. In rare cases of coronary artery anomalies, the apex of the heart may be supplied by arteries other than the left anterior descending artery. While it is more common for the posterior descending artery from the right coronary artery to supply the apex, there are rare instances where the left circumflex (LCX) artery performs this function. This case report describes an unusual occurrence where the left ventricular apex is supplied by an obtuse marginal branch of the LCX artery. We present this case due to its rarity, unique presentation, and the challenges it poses for both medical and surgical management.
