PURPOSE: To compare balloon valvuloplasty and surgical valvulotomy in the management of pulmonary valvar stenosis.
PATIENTS AND METHODS: Balloon pulmonary valvuloplasty was performed in 10 consecutive patients, 6 girls and 4 boys, age ranges 3 to 19 years (mean 11), between April 1987 to November 1988.
RESULTS: Immediate hemodynamic and angiographic changes consisted in reduction of the peak transvalvular gradient from 93 +/- 42 mmHg to 39 +/- 26 (p less than 0.01), the right ventricular systolic pressure from 108 +/- 16 mmHg to 58 +/- 27 mmHg (p less than 0.01) and in increasing of the pulmonary valve diameter from 9.59 +/- 3.28 mm to 19.55 +/- 6.16 mm (p less than 0.01) and the systolic pulmonary artery pressure from 15.15 +/- 3.28 mmHg to 18.4 +/- 6 (NS). No relationship between right ventricular systolic pressure and transpulmonary valvular gradient could be found. We only observed one case of mild pulmonary insufficiency as a complication of the procedure. The intermediate follow up (7 to 14 months), in 4 of 10 patients showed maintenance of the initial finding.
CONCLUSION: The results of the percutaneous pulmonary valve valvuloplasty are as good as those obtained by the surgical valvulotomy.
