Percutaneous Coronary Intervention in a Patient Presenting With Inferior Myocardial Infarction and an Anomalous Left Main Artery Originating From the Right Coronary Sinus

Abstract

We present a case of a patient with inferior myocardial infarction (MI) and anomalous left main artery originating from the right coronary sinus. The left main artery and right coronary artery originated from the right coronary sinus but with separate ostia. The patient underwent revascularization of the right coronary artery with balloon angioplasty and a drug-eluting stent. Despite being rare, these anomalies can be life-threatening depending on the course of the artery, and when atherosclerotic disease is present, a revascularization strategy can be challenging. Knowing the existence of the left main artery anomaly is important to choose the right guide catheter to achieve successful cannulation and decrease the risk of complications, radiation exposure, and contrast usage.
