Anomalous single coronary artery presenting with acute myocardial infarction

The anomalous origin of the entire coronary system from the right coronary sinus is a very rare anomaly. Here a patient with this rare anomaly,who developed acute coronary syndrome,requiring revascularization,is presented and treated successfully. His coronary angiographic findings are also discussed. We would like to highlight the rarity of the origin of all 3 coronary arteries from a single coronary trunk. The case also highlights the importance of using Amplantzer AR1 guiding catheter for such anatomical variations arising in the right coronary cusp.
