Overall, 54.5% achieved biventricular (BiV) repair, 26.7% underwent functionally single-ventricle palliation, and 18.8% were noncommitted. Overall group in-hospital mortality was 11.7%. The median follow-up was 8.9 years, with 1- and 5-year mortality of 19.8% (95% CI, 16.2%\u201323.2%) and 20.8% (95% CI, 17.1%\u201324.4%), respectively. Stage 1 palliation as the initial therapy had higher 1-year mortality than right ventricular decompression (37.2% [29.0%\u201344.5%] versus 7.7% [4.5%\u201310.7%]). Cardiac reintervention was 62.6% (56.1%\u201368.4%) at 10 years after BiV repair and 32.8% (21.5%\u201344.4%) at 10 years after palliative stage 3. Median hospital stay was greatest in the first year (35 days), declining to 2 days annually by 10 years, with functionally single-ventricle patients requiring more days in hospital than BiV patients (52 versus 28).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>In a contemporary pulmonary atresia with intact ventricular septum cohort, transcatheter right ventricular decompression was the predominant initial intervention. This approach had lower in-hospital mortality compared with older multicenter series, with BiV repair achieved in more than half of the patients. Early mortality after nonantegrade flow augmentation remains high, likely due to nonmodifiable risk factors in severe cases. Long-term survival and hospital stay remain better for those amenable to BiV circulation, reflecting more favorable anatomy compared with those on the single-ventricle pathway, although reintervention is lower in the latter.<\/jats:p>\n
