Long-term outcomes of aortic valve repair in children after infancy

Abstract

Background: We evaluated the long-term outcomes of children who underwent aortic valve repair after infancy. Methods: A retrospective, single institutional study of all children aged 1 year or more who underwent primary aortic valve repair between 1980 and 2024 was performed (N = 326). Results: The median age of patients at time of aortic valve repair was 9.4 years (interquartile range, 4.8-14.2). Repair was achieved without patch material in 49.7% of patients (162/326). Early mortality was 0.61% (2/326). Late death was 1.85% (6/324). Median follow-up was 9.04 (interquartile range, 3.4-16.6) years. Kaplan–Meier estimated survival at 10, 15, and 20 years was 98.4%, 97.9%, and 94.9%, respectiv..
