Atypical presentation of an anomalous origin of the right coronary artery with severe compression between the great vessels.

Anomalous aortic origin of the right coronary artery is a rare coronary anomaly which, in a minority of cases, can cause clinical manifestations such as ischemic chest pain or arrhythmic syncope. We describe a case of anomalous aortic origin of the right coronary artery characterized by signs of left heart failure associated with ventricular tachycardia.
