Implication
Supports early repair timing in pulmonary valve stenosis; leaves open causal mechanisms and need for prospective confirmation.
Structured PICO
What is the long-term survival of patients undergoing surgical repair of isolated pulmonary valve stenosis compared to an age- and sex-matched control population?

Population
191 consecutive patients with isolated pulmonary valve stenosis who underwent surgical repair between 1956 and 1967 at the Mayo Clinic

Intervention
Surgical repair of isolated pulmonary valve stenosis
C
Comparator
Age- and sex-matched control population
O
Outcome
Long-term survival at 20-30 years follow-uphard clinical
Surgical repair of isolated pulmonary valve stenosis before age 21 restores normal life expectancy, whereas older age at operation is associated with poorer long-term survival compared to matched controls.
