We report a rare case of anomalous aortic origin of the right coronary artery from the posterior/non-coronary sinus of Valsalva in a 9-year-old male diagnosed during the workup of premature ventricular contractions. The finding was initially noted on transthoracic echocardiogram and further confirmed with computed tomography. The anomalous coronary artery shows a wide ostium with no intramural or interarterial course.
