Abstract
Aim – to estimate the mid-term results of aortic valve commissurotomy in patients with congenital aortic
valve (AV) stenosis.
Material and methods. In 2000–2016, 52 patients underwent blade commissurotomy for congenital aortic
valve (AV) stenosis. Mean age was 8.5±3.8 years, 36 were boys and 16 girls. Aortic valve was bicuspid in 81%
of cases. All patients had peak gradient above 40 mm Hg, with normal left ventricular function and no or trivial
AV insufficiency. Surgery was performed in moderate hypothermia with Custodiol® solution.
Results. There were no in-hospital mortality, men gradient at discharge was 28.0±10.0 mm Hg. Follow-up
was complete in 44 patients with mean interval 4.8±1.6 years. Reoperation freedom was 86%, progression
of AV insufficiency had being observed in 5 patients and 3 patients needed aortic valve replacement.
Conclusion. Aortic valve commissurotomy is an effective way to relief AV stenosis and could safely performed
in children. Mid-term follow-up shows acceptable hemodynamic outcome and good reoperation freedom.
