Aim: The aim of the treatment of isolated valvular pulmonary stenosis (IVPS) is to remove or reduce severe stenosis of the pulmonary valve without surgical intervention. Patients and methods: Our retrospective study involved 32 patients with average age of 41.5 years (mean age 43.5 years). In 19 women (59.4 %) and 13 men (40.6 %) anatomical, morphological, haemodynamic and functional success of balloon percutaneous transluminal pulmonary valvuloplasty (BPTPV) was evaluated. Following parameters were evaluated: peak systolic gradient (PSG), index of systolic intraventricular pressures ISIVP and pulmonary valve surface area index (PVSAI). Result: Before BPTPV the average PSG was 96.6 mmHg. After it, PSG was reduced to 37.8 mmHg (p < 0.001). The average ISIVP before the intervention was 1.08, and after the intervention 0.46 (p < 0.001).The average PVSAI was 0.46 cm2/m2. After BPTPV it increased to 0.83 cm2/m2 (p < 0.001). In long term follow-up 84.4 % of patients benefited from the treatment (average functional classification NYHA 2.0). Conclusion: BPTVP is, in the treatment of IVPS, the method of the first and mostly definite choice due to its very good therapeutic results, lower cost and lower invasiveness.
