title: [Treatment of percutaneous angioplasty of restenoses of coarctation and stenosis of bioprostheses in children].
abstract: The authors discuss the percutaneous balloon dilatation procedure and the results obtained in 10 children (age range: 2.5-13 years) over a 2 year period (April 1986-April 1988). Six cases of coarctation restenosis were observed and good clinical and hemodynamic results were noted in 2 cases, while in 4 cases the procedure was not totally successful. For the 4 cases of stenosis of bioprosthetic valves in right ventricular-to-pulmonary arterial conduits, good results were obtained with a significant reduction of the trans-stenotic gradient from 50 to 23 mmHg. While long-term effectiveness of the procedure is still uncertain, those encouraging preliminary results suggest that this procedure could be considered as an alternative treatment for coarctation restenosis and stenosis of bioprosthetic valves in right ventricular to pulmonary artery conduits.
