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

Anomalous aortic origin of the left coronary artery (AAOLCA) from the right sinus of Valsalva is a very rare coronary 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 stronger relationship with SCD In patients with AAOLCA, ST-segment elevation myocardial infarction (STEMI) is a rare clinical presentation. and the management of an anomalous infarct-related coronary artery may be technically challenging. We report a case of a patient with an AAOLCA who presented with inferior STEMI and who underwent a successful percutaneous coronary intervention of the right coronary artery.
