<jats:title>Abstract</jats:title><jats:p>Irrespective of previous procedure in congenital aortic stenosis, aortic surgery later in life may be indicated. The aim of the present study was the analysis of indications, risks, and outcomes of aortic surgery after previous aortic valve procedure. The data of patients who underwent aortic surgery after previous treatment of congenital aortic stenosis in a 10‐year period (from 2000 to 2009) were retrospectively analyzed. Thirty‐two patients (23 male and 9 female) underwent redo aortic surgery. The mean age at surgery was 13.5 ± 11.3 years. Seventeen patients had undergone initial aortic balloon valvuloplasty (<jats:styled-content style="fixed-case">BVP</jats:styled-content>) and 15 patients open commissurotomy (<jats:styled-content style="fixed-case">COM</jats:styled-content>). Nine cases had undergone the primary procedure at neonatal age and two patients had undergone cardiac surgery before the initial aortic valve procedure. Seven of the patients with previous <jats:styled-content style="fixed-case">COM</jats:styled-content> (43.8%) had undergone concomitant surgery along with initial commissurotomy. A reintervention within the first year after the primary procedure was performed in seven patients (seven after <jats:styled-content style="fixed-case">BVP</jats:styled-content> and none after <jats:styled-content style="fixed-case">COM</jats:styled-content>; <jats:italic>P</jats:italic> < 0.05). The interval between the last intervention and the first redo aortic surgery was 7.5 ± 9.5 years (3.1 ± 3.5 years after <jats:styled-content style="fixed-case">BVP</jats:styled-content> vs. 12.5 ± 11.7 years after <jats:styled-content style="fixed-case">COM</jats:styled-content>; <jats:italic>P</jats:italic> < 0.05). A second redo surgery was performed in nine patients (four after initial <jats:styled-content style="fixed-case">BVP</jats:styled-content> and five after <jats:styled-content style="fixed-case">COM</jats:styled-content>). Congenital aortic stenosis is very often presented in combination with additional pathologies. These concomitant diseases along with the underlying disease give the indication for reoperation. Reinterventions are more often indicated after primary <jats:styled-content style="fixed-case">BVP</jats:styled-content>. Long follow‐up in specialized centers is mandatory.</jats:p>
