Median age at surgery was 3.1 months (range 2.4\u20134.7 months). Median preoperative PV <jats:italic>Z<\/jats:italic>\u2010score was \u22122.5 (range \u22121.4 to \u22123.12) and the median peak right ventricle outflow tract (RVOT) gradient was 80 mm Hg (range 49\u201390 mm Hg). No procedure\u2010related complications were reported. The size of the PV annulus after the balloon dilation was appropriate for body surface area in all patients. Median follow\u2010up time was 1.4 years (range 0.5\u20133.3 years). Reoperation was needed in one patient 3 months after repair because of residual subvalvar RVOT obstruction. The remaining 15 patients are alive and well. The median PV <jats:italic>Z<\/jats:italic>\u2010score is 0 (range \u22120.2 to 1). Median peak RVOT gradient is 20 mm Hg (range 12\u201332 mm Hg). The PV is competent in seven patients; mild PV regurgitation is present in seven patients and moderate in one.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The integrity of the PV annulus and PV function can be preserved in selected patients during early repair of TOF when using concomitant balloon dilation.
