Abstract
Percutaneous balloon catheter dilatation of the pulmonary valve has become a widely accepted therapeutic alternative to surgical valvotomy: immediate and shortterm clinical and hemodynamic improvements have been documented.
1–4 This study evaluates 1- to 2-year followup results in the first consecutive series of adult patients with congenital pulmonary valve stenosis (PS) to undergo percutaneous double balloon pulmonary valvotomy.
