Percutaneous transluminal balloon valvuloplasty for pulmonary valve stenosis

Abstract

Transluminal balloon valvuloplasty was used to treat congenital pulmonary valve stenosis in 20 patients. Follow-up cardiac catheterization was performed in 11 patients at intervals of from 2 to 12 months after the procedure. Peak systolic pressure gradient across the pulmonic valve decreased from 68 ± 27 to 23 ± 5 mm Hg (p
