Six patients underwent a definitive Rastelli operation, and five underwent palliative right ventricle-to-pulmonary artery conduit formation. The median age at the time of operation was 61 (range, 6-462; interquartile range [IQR]: 229) days, and the median weight was 4.0 (range, 3.0-11.6; IQR: 4.3) kg.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>One patient died early due to brain hemorrhage, and one died late due to sepsis. The follow-up duration was 38.5\u2009\u00b1\u200918.9 months. The mean peak pressure gradients across the conduit were 6.5\u2009\u00b1\u20094.4 mm Hg at discharge and 22.0\u2009\u00b1\u200911.2\u2005mm Hg at the latest follow-up echocardiography. Regarding conduit regurgitation, all conduits showed better than moderate grading at the last follow-up or before reintervention. There were seven conduit explantations and three catheter interventions for conduit-related reasons. The explantations included a definitive Rastelli operation in three patients and conduit stenosis due to somatic growth in four patients.<\/jats:p>\n                  <\/jats:sec>\n
