BACKGROUND: This study analyzed the long-term outcome after operations for open aortic valvotomy, specifically looking at the preservation of the native aortic valve. METHODS: Between 1983 and 2011, 34 neonates with critical aortic stenosis underwent open valvotomy. The mean age at operation was 15 days (range, 1 to 28 days). Follow-up was 100% complete. RESULTS: Three patients died early. The probability of survival was 91.2%, with a mean follow-up of 11 years (range, 10 months to 21 years). Event-free survival was 77%, 68%, 68%, and 57% at 5, 10, 15, and 20 years, respectively, and freedom from aortic valve replacement was 93%, 83%, 68%, and 57%. Tricuspid valve morphology revealed the best outcome, with event-free survival of 90% (p = 0.006) and 100% freedom from aortic valve replacement (p = 0.0012) at 20 years of follow-up. All but 4 patients were in New York Heart Association class I; 77 % of all patients were without medication. CONCLUSIONS: 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.
