Modified Barbero-Marcial repair for type I truncus arteriosus in a 2.7-kg neonate

Multimed Man Cardiothorac Surg. 2022 Jan 31:2022. doi: 10.1510/mmcts.2022.002.


Truncus arteriosus is a rare cardiac anomaly, accounting for less than 4% of all congenital lesions. It is the result of failed aorticopulmonary septation during the fifth week of gestation leading to a single arterial trunk overriding the interventricular septum, a single semilunar valve, and typically a large conotruncal ventricular septal defect. Several classifications exist, and it typically requires surgical repair in the neonatal period. We present a 5-day old female neonate who was diagnosed postnatally with type I truncus arteriosus in which the pulmonary arteries arose from a discrete pulmonary trunk that originated from the posterolateral aspect of the common arterial trunk. A successful repair was undertaken using a variant of the Barbero-Marcial technique.
