Background: Outcomes after right ventricle (RV) decompression in infants with pulmonary atresia with intact ventricular septum vary widely. Descriptions of outcomes are limited to small single-center studies.

Methods And Results: Neonates undergoing RV decompression for pulmonary atresia with intact ventricular septum were included from 4 pediatric centers.
