Aorto-pulmonary window and anomalous right coronary artery originating from the pulmonary artery in a child

A two-year-old boy was admitted to hospital because he had a continuous murmur for two months with no apparent symptoms. The echocardiograph revealed a type I aorto-pulmonary window (APW) and mild tricuspid regurgitation with a suspicious anomalous right coronary artery originating from the pulmonary artery (ARCAPA) (white arrow in Fig. 1A and B).
