There were 23 (28.4%) deaths, with 15 (18%) occurring in-hospital. Ten-year survival was 72.7%. Longer cardiopulmonary bypass times and extracorporeal membrane oxygenation (ECMO) requirement were associated with in-hospital mortality, while younger age showed a borderline association (P\u2009=\u2009.05). At 10 years, the cumulative incidence of reintervention was 72.6%, mostly due to a high rate of right ventricle to pulmonary artery (RVPA) conduit reintervention (52.2% at 10 years), but with a low pulmonary autograft reintervention rate (7.6% at 10 years).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Outcomes of Ross (-Konno) operations in patients younger than 1 year reflect the high complexity of this population. Early mortality is significant with acceptable long-term survival rates. The pulmonary autograft in aortic position has good durability with few reinterventions, while RVPA conduits have demonstrated a high number of reinterventions.<\/jats:p>\n
