Recurrent ST-Elevation Myocardial Infarction in a Single Coronary Artery: A Rare Anomaly

Single coronary artery anomalies are those where the entire myocardium is supplied by an artery arising from one ostium. It is a rare coronary anomaly and has been there in literature ever since 1867. Over the years, this has intrigued anatomists and physicians whether its presence has life-threatening consequences or is mere a benign entity. Most of the cases are generally silent except for the interarterial course variants which are associated with sudden deaths. We report the case of a patient presenting with recurrent inferior wall ST-elevation myocardial infarction who was found to have a single coronary artery on angiography. The patient underwent primary percutaneous coronary intervention and uneventful further course.
