[Pulmonary valvuloplasty in adolescents and adults: 2 year follow-up by continuous Doppler].
The purpose of this study is the long term follow-up of the first pulmonary valvuloplasties performed by our group. From september 1984 to march 1988, 10 patients (4 men and 6 women) aged 8 to 58 (mean: 21) with severe or moderate pulmonary valve stenosis underwent pulmonary valvotomy. In all cases the balloon diameter was equal to or 1 mm smaller than the valvular annulus. The results were satisfactory with a significant mean gradient reduction of 51.7%. A follow-up gradient estimation by Doppler echocardiogram was obtained 10 to 37 months after valvuloplasty (mean: 23 months). The mean follow-up gradient by Doppler (31.3 +/- 9.9 mmHg) was not significantly different from the mean hemodynamic post-dilatation gradient (35.6 +/- 14.7 mmHg). A linear correlation was found between the post-dilatation hemodynamic mean gradient and the mean gradient by Doppler follow-up (r = 0.66, p less than 0.05, SEE = 4.1 mmHg). No restenosis were observed. These results suggest that the benefits of valvuloplasty are long lasting. Continuous Doppler is an excellent technique for the follow-up of these patients.
