Percutaneous Coronary Intervention in A Rare Case of Single Coronary Ostium Presented with ST Elevation Myocardial Infarction

Abstract

Anomalous aortic origin of the left coronary artery (AAOLCA) from the right sinus of Valsalva is a very rarecoronary anomaly that can lead to sudden cardiac death (SCD), usually during or after strenuous exercise.The anatomical variation can follow five different courses: interarterial, subpulmonic (intraconal or intraseptal),prepulmonic, retroaortic, or retrocardiac. The interarterial variation is the pattern that has a strongerrelationship with SCD. In patients with AAOLCA, ST-segment elevation myocardial infarction (STEMI) is arare clinical presentation, and the management of an anomalous infarct-related coronary artery may betechnically challenging. We report a case of a patient with an AAOLCA who presented with inferior STEMIand who underwent a successful percutaneous coronary intervention of the right coronary artery.
