Anomalous origin of the left coronary artery from the right sinus of Valsalva is a congenital anomaly When the left coronary artery (LCA) originates from the right sinus of Valsalva, the anomalous artery pathway can present in four variants. We report a case in which a patient presented with episodes of atypical chest pain and during coronary angiography it was found that his left coronary artery originated anomalously from the right coronary sinus and course of the LCA was confirmed by CT coronary angiography. Importance of anomalous origin of coronary artery and specially its course shall be discussed in this case report.
