This case report highlights the utility of multimodality imaging in identifying rare complex congenital cardiac anomalies such as bilateral ductus arteriosus supplying non-confluent pulmonary arteries.

Rare bilateral ductal pulmonary supply in heterotaxy warrants multimodality imaging for diagnosis; leaves open optimal palliation strategies in single ventricle physiology.
The images presented show heterotaxy (right atrial isomerism), mitral and pulmonary valve atresia, single ventricle physiology, non-confluent branch pulmonary arteries supplied by ipsilateral ductus, and a large VSD. Non-confluent branch pulmonary arteries which are supplied by bilateral ducts are a rare cardiac anomaly which is illustrated by multimodality imaging in this patient.
