This single institution study adds evidence that a modestly “oversized” RV-to-PA conduit
is optimal in truncus arteriosus repair. An optimal conduit type, however, remains
elusive.

- PreviewWe studied conduit-related risk factors for mortality, conduit reintervention, conduit replacement, and pulmonary artery (PA) reinterventions after truncus repair. Patients who underwent truncus repair at our institution between 1995 and 2019 were studied. Cox proportional hazards modeling evaluated variables for association with mortality, time to conduit reintervention, time to conduit replacement, and time to PA reintervention. Truncus was repaired in 107 patients at median age of 17 days (IQR 9–45).
