    Abstract:
    Percutaneous pulmonary balloon valvuloplasty (PBV) is a well-established treatment alternative to surgery in many cardiology centers. We described our experience with PBV in 25 adolescent and young adult patients with isolated pulmonary valve stenosis (PVS). Among 20 successful PBVs, there was a significant immediate decrease in right ventricular systolic pressure from 116.9 32.4 mmHg to 60.5 18.7 mmHg (p < 0.0001) and a decrease in transpulmonary valve pressure gradient from 93.5 32.8 mmHg to 33.5 9.7 mmHg (p < 0.0001) was noted. The follow-up period was 1-5 years (mean = 3.2 1.2 years), during which patients were periodically assessed by Doppler echocardiogram. During follow-up, the transpulmonary valve pressure gradient further decreased from 33.5 9.7 mmHg to 18.6 3.4 mmHg (p < 0.0001) mainly due to regression of infundibular hypertrophy. Thus, the study showed excellent short-term and intermediate-term results of PBV.
