Aim: The aim of the treatment of isolated valvular pulmonary stenosis is to remove or reduce severe stenosis of the pulmonary valve

without using surgical intervention.

Patients and metods: Our retrospective study involved 30 patients of average age of 41.1 years (mean age 43 years). In 18 women (60 %)

and 12 men (30 %) anatomical, morfological, hemodynamics and functional success of percutaneous transluminal pulmonary valvuloplasty

(PTPV) was evaluated. Following parameters were evaluated: Peak systolic gradient (PSG), index of systolic intraventricular pressures

(ISIVP) and pulmonal valve surface area index (PVSAI).

Result: Before PTPV the average PSG was 95,7 mm Hg. After PTPV PSG was reduced to 38.8mmHg (p < 0.001). The average ISIVP before

intervention was 1.09, after intervention 0.45 (p < 0.001). The average PVSAI was 0.46 cm2/m2. After PTPV an increase to 0.82 cm2/m2. In

long term follow-up 83.3 % patients benefit from the treatment (average functional classification NYHA 2.0).

Conclusion: PTPV is, in the treatment of isolated valvular pulmonary stenosis, the method of the first and most definite choice for very

good therapeutic results, lower costs and lower invasiveness.
