[Percutaneous pulmonary valvuloplasty in adults. An immediate evaluation and follow-up of 3 cases].

The immediate and late results of percutaneous pulmonary valvuloplasty in three symptomatic adult patients (21, 38 and 45 years) with severe pulmonary valve stenosis are reported. The right ventricle-pulmonary artery gradient fell from 135 mmHg to 50 mmHg in patient n. 1, from 124 mmHg to 95 mmHg in patient n. 2 and from 132 mmHg to 27 mmHg in patient n. 3. Six months later a further hemodynamic study showed a further reduction in the gradient in patient n. 1 and n. 2 (28 and 33 mmHg). A year and half after of clinical follow-up symptomatic improvement is still present without any clinical or echo-Doppler signs of restenosis. In conclusion, percutaneous pulmonary valvuloplasty is a simple and safe procedure for severe pulmonary valve stenosis even in adults with immediate and long-term good results.
