The anomalous aortic origin of the left coronary artery from the right coronary sinus is a rare congenital anomaly. Transthoracic echocardiography (TTE) has limited accuracy to detect coronary anomalies in adults. A highly specific TTE finding (RAC sign) has been recently described as strongly associated to retroaortic anomalous coronary course. Cardiologists should be aware of the appearance and significance of the RAC sign, so that it is not ignored or misdiagnosed.

Abstract
The anomalous aortic origin of the left coronary artery from the right coronary sinus is a rare congenital anomaly. Transthoracic echocardiography (TTE) has limited accuracy to detect coronary anomalies in adults. A highly specific TTE finding (RAC sign) has been recently described as strongly associated to retroaortic anomalous coronary course. Cardiologists should be aware of the appearance and significance of the RAC sign, so that it is not ignored or misdiagnosed.| File | Dimensione | Formato | |
