Abstract

We present the case of a 55-year-old man who had a diagnosis of an acute anterior ST-segment elevation myocardial infarction. Emergency angiography demonstrated that both coronary systems originated from the right coronary sinus with a culprit proximal left anterior descending artery lesion, which was stented. This is a rare presentation, with only 1 similar case found in published reports. (Level of Difficulty: Intermediate.).
