Short- and long- term results of percutaneous balloon valvuloplasty in pulmonary valve stenosis

To assess the long-term results of percutaneous balloon valvuloplasty at a single institution. This study comprised 189 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty from 1984 to 1996, whose mean age was 7.97+/-9.25 years. The procedure was classified as succes...

Zusammenfassung:To assess the long-term results of percutaneous balloon valvuloplasty at a single institution. This study comprised 189 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty from 1984 to 1996, whose mean age was 7.97+/-9.25 years. The procedure was classified as successful when the RV-PA gradient was reduced to levels < 36 mmHg; restenosis was indicated by RV-PA gradients > 36 mmHg after an effective procedure. After the procedure, the peak-to-peak transvalvular gradient decreased from 70.12+/-30.06 to 25.11 +/-20.23 mmHg (P
