Key result
Childhood surgical pulmonary stenosis repair is linked to ~91% 40-year survival, but reinterventions remain common.
Why the study?
Long-term prospective data on outcomes after surgical correction of valvular pulmonary stenosis during childhood are limited.
Population
53 consecutive patients operated for valvular pulmonary stenosis during childhood between 1968 and 1980
Design
Prospective longitudinal cohort study with in-hospital examinations every 10 years
Follow-up
37±3.4 years

Supports excellent long-term survival after childhood PS repair; extends prior cohorts but leaves open reintervention predictors and LV dysfunction prevention.
Cohort (n=53)
No
Survival up to 40 years after surgical repair of pulmonary stenosis in childhood is excellent (91%), though 25% require reintervention and 41% develop left ventricular dysfunction.
Cuypers et al. (2016) conducted a cohort in Valvular pulmonary stenosis (n=53). Surgical correction of valvular pulmonary stenosis was evaluated on Cumulative survival at 40 years. Surgical correction of valvular pulmonary stenosis during childhood was associated with a 91% cumulative survival at 40 years, though 25% of patients required reintervention.
