Figure 4: Angiograms confirming diagnosis of anomalous origin of a coronary artery from the pulmonary artery (ALCAPA) in case 2 (14 year old). Panel 4A is right anterior oblique view of aortogram showing only right coronary artery (RCA) originates from aorta. Left coronary artery is not originating from aorta. Panel 4B is selective right coronary artery angiogram in right anterior oblique view showing retrograde filling of left coronary artery via collateral branches from RCA. Left coronary artery empties into main pulmonary artery (MPA)
