title: [Treatment using balloon catheterization of pulmonary valve stenosis].
abstract: From October 84 to September 88 we performed pulmonary valvuloplasty with balloon catheter (PVBC) in 90 patients (pt) with pulmonary valve stenosis (PVS). The patients were divided in 3 groups (Gr) by their ages: group I (Gr. I) 7 pt (8%) aged 4 days to 11 months, Gr. II 66 pt (73%) aged 1 year to 12 years and Gr. III 17 pt aged 13 to 34 years. This study consists of clinical and echocardiographic evaluation adopting the following parameters of indication: a) transvalvar pulmonary gradient (G); b) absence of dysplasia or hypoplasia of the pulmonary annulus. There were associated lesions which were found in each group: Gr. I atrial septal defect (ASD) in 2 pt and tricuspid insufficiency (TI) in 1 pt, in Gr. II supra valvar stenosis (SVS) in 1 pt and patent arterial ductus (PAD) in 1 pt and in the Gr. III (ASD) in 1 pt. The results after pulmonary valvuloplasty with balloon catheter (PVBC) were: (Gr.I) in 5 pt the G were reduced below 50 mmHg and the average of right ventricular systolic pressure (RVSP) changed from 92 to 62 mmHg and the average of G from 76 to 44 mmHg. One of these pt was submitted to surgery 1 month after the procedure and 2 developed restenosis in 2 and 3 years respectively, being submitted to another dilatation with good results. The 2 pt in which the procedure was not effective were submitted to surgery. In the second group the PVBC was effective in 61 pt (92%) showing the RVSP changed from 118 to 64 mmHg and G changed from 86 to 23 mmHg.(ABSTRACT TRUNCATED AT 250 WORDS)
