The Long-Term Outcome of Open Valvotomy for Critical Aortic Stenosis in Neonates

In neonates, predictable and consistent long-term results can be accomplished by open valvotomy in any type of valve morphology, even in an asymmetric arrangement. Operative repair not only offers a 90% survival benefit in the long-term but also preserves the native aortic valve in most patients. Clearly superior results were achieved in tricuspid valve morphology, in which there was no need for aortic valve replacement at 20 years of follow-up.
