Treatment
Definitive surgical correction may be performed as a single-stage repair within the 1st month of life. The procedure is indicated for truncus arteriosus without truncal valve or aortic arch abnormality. Pulmonary artery mobilization from the truncus to the right ventricle, conduit-based right ventricular outflow tract reconstruction, and VSD patch closure are performed within the same operation. Aortic arch abnormalities and the truncal valve are also fixed.
Primary palliation with pulmonary arterial banding and delayed surgical repair may be required to allow the infant to grow. However, this 2-stage correction is not routinely recommended due to higher morbidity and mortality rates.
