Outcome of truncus arteriosus repair: 20 years of single-center experience comparing early versus late surgical repair.

In general, the outcome of early truncus arteriosus repair is excellent with resolution of pulmonary hypertension following early repair. Late repair caries higher risk of persistent pulmonary hypertension (37.5%). About one-third of the patients who had truncus arteriosus repair will require re-intervention within 38±38.4 months after initial surgery.
