title: Surgical treatment of congenital pulmonary stenosis due to dysplastic leaflets and small valve anulus.
abstract: Seven cases of pulmonary valve stenosis due to congenital dysplasia of the valvular apparatus have been corrected by patch-graft enlargement of the right ventricular outflow tract. The six surviving patients (85%) are now leading normal lives with good exercise tolerance. The satisfactory right ventricular performance, manifested by these subjects after the operation and in the long-term follow-up, supports the validity of the procedure in the presence of a normal right ventricle and tricuspid valve.
