Overall, the groups were well matched with 18 neonates\/25 infants in the balloon group and 17 neonates\/28 infants in the surgical group. Median age at balloon was 92 days (range 2 days \u2013 18.8 years) compared to 167 days (range 0 days \u2013 18.1 years) for surgery (rank-sum p = 0.08). Mean follow-up was 5.3 years. There was one late balloon death and two early surgical deaths due to left ventricular failure. There was no significant difference in freedom from reintervention at latest follow-up (69% in the balloon group and 70% in the surgical group, p = 1.0).<\/jats:p><\/jats:sec><jats:sec id=\"S1047951121001281_as5\"><jats:title>Conclusions:<\/jats:title><jats:p>Contemporary analysis of balloon aortic valvuloplasty and surgical aortic valvotomy shows no difference in overall reintervention rates in the medium term.
