Fate of Right Ventricle to Pulmonary Artery Conduits After Complete Repair of Pulmonary Atresia and Major Aortopulmonary Collaterals

Conduit z scores and conduit size worked synergistically to predict the longevity of right ventricle to pulmonary artery conduits after complete repair of PA/VSD/MAPCAs. Pulmonary artery pressure was an additional modifier of longevity. These data provide a framework for expectations of aortic homograft conduits used in the repair of PA/VSD/MAPCAs.
