Does transluminal balloon valvuloplasty reduce peak systolic pressure gradient in patients with congenital pulmonary valve stenosis?
Transluminal balloon valvuloplasty safely and effectively reduces the peak systolic pressure gradient in patients with congenital pulmonary valve stenosis.
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 less than .001) after valvuloplasty. There were no complications. Follow-up catheterization demonstrated persistent relief of right ventricular hypertension in the patients with typical pulmonary valve stenosis.
