Results of pulmonary balloon valvuloplasty persist and improve at late follow-up in isolated pulmonary valve stenosis

Abstract

Pulmonary balloon valvuloplasty remains a safe and effective treatment for children with isolated pulmonary valve stenosis, with excellent long-term outcomes and no mortality. A few patients require further intervention. Long-term follow-up demonstrates decreased, residual stenosis. Patients have a small, acute increase in pulmonary regurgitation following valvuloplasty, but no long-term progression.
