Parasternal short axis view in a patient with anomalous origin of the right coronary artery from the pulmonary artery. The proximal right coronary artery passes anterior to the right aortic sinus of Valsalva and enters the proximal pulmonary artery. The pulmonary sinus of origin cannot be determined from this view. With the addition of color Doppler, retrograde flow is demonstrated in the right coronary artery and also into the pulmonary artery. This movie demonstrates the value of obtaining a loop and slowing the playback to understand better the contiguity of the right coronary artery, which has a high amplitude of translation throughout the cardiac cycle.
