Patent ductus arteriosus stenting as therapeutic bridge in a patient with type A3 truncus arteriosus variant with multiple comorbidities

Cardiol Young. 2024 Feb;34(2):370-372. doi: 10.1017/S1047951123001658. Epub 2023 Jul 12.


Type A3 truncus arteriosus describes pulmonary atresia with non-confluent mediastinal pulmonary arteries in which one pulmonary artery arises from a patent ductus arteriosus and the contralateral pulmonary artery from the aorta resulting in ductal dependent pulmonary blood flow. We describe a premature neonate with caudal regression syndrome and type A3 truncus arteriosus who was palliated with a ductal stent allowing completion of a prolonged neonatal ICU hospitalisation for multiple comorbidities.

Keywords: CHD; Truncus arteriosus; computed tomography angiography.
