Longevity of Large Aortic Allograft Conduits in Tetralogy With Major Aortopulmonary Collaterals

The programmatic use of oversized aortic homograft RV-PA conduits in the surgical repair of MAPCAs provides a focused experience that demonstrates similar longevity to reported best alternatives. Secondarily, conduit oversizing may improve durability and enables an increased likelihood of non-operative reintervention.
