The median age was 13 (interquartile range [IQR]: 1.8-25) years. During the median follow-up duration of 8.5 years (IQR: 8 months-15.8 years), 18 patients required reoperation at a mean of 7.3\u2009\u00b1\u20094 years. The 15-year survival rate was 95.6% (95% confidence interval [CI], 88%-98.8%), and 2 late deaths occurred. The freedom from reoperation at 1, 5, and 12 years was 100% (95% CI, 100%-100%), 82.8% (95% CI, 66.6%-91.4%), and 44.2% (95% CI, 26.2%-61%), respectively. At discharge, the mean peak systolic aortic valve gradients (15\u2009\u00b1\u200910\u2005mm Hg) were significantly lower than preoperative (72\u2009\u00b1\u200935\u2005mm Hg) values (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.001). Mean of left ventricular end-diastolic diameter\/body surface area index decreased from 38\u2009\u00b1\u200913 mm preoperatively to 34.4\u2009\u00b1\u200910.5 mm postoperatively, then reduced to 32\u2009\u00b1\u20097 mm at the latest follow-up (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.003).
