Highlights
• Echocardiography can delineate complex congenital anatomy without additional imaging.
• A wide range of branch pulmonary artery anatomy is seen in pulmonary atresia.
• Bilateral patent ductus arteriosus is an uncommon finding in pediatric cardiology.

... Current literature includes mainly case reports or small case series of PDA. The cases previously reported included bilateral PDA in isolation, associated with congenital heart disease including various forms of pulmonary atresia, aortic arch anomalies including aortic atresia or interrupted aortic arch, and isolation of one subclavian artery [3][4][5]. ...
Bilateral PDA is an infrequent entity and is seen in a wide range of presentations. The cases previously reported included bilateral PDA in isolation, associated with congenital heart disease including various forms of pulmonary atresia, aortic arch anomalies including aortic atresia or interrupted aortic arch, and isolation of one subclavian artery. Knowledge of detailed cardiac anatomy is a prerequisite for a successful surgery. For this, complementary imaging to echo cardiography such as computed tomography is required to delineate both the intra cardiac and extra cardiac anatomy fully.
We present a rare case of double-outlet right ventricle with pulmonary atresia and discontinuous branch pulmonary arteries supplied by bilateral ducti from a right aortic arch. To our knowledge, this is only the second documented case of double-outlet right ventricle with bilateral ducti. (Level of Difficulty: Advanced.)
