title: [Stent dilatation of pulmonary artery stenosis in the adult patient with congenital heart disease].
abstract: Stents have been previously used to resolve stenoses of branch pulmonary arteries in children. We report 3 patients, with mean age of 22.7 +/- 4.7 years and pulmonary artery stenosis after palliative surgery in whom we implanted seven stents in four procedures. Six P308 Palmaz, overlapped two by two, were implanted by venous femoral approach in two patients, receiving four in the first case and the other two in the third case. In the second case, a NIR type stent was implanted through femoral artery in the right pulmonary artery. Stenosis diameter enlarged from 5.3 +/- 2.3 to 14.4 +/- 4.2 mm and the pressure gradient through stenosis fell from 40.6 +/- 15.3 to 6. 5 +/- 5 mmHg. All stents are well deployed and there are two patients waiting for total correction (previously not feasible) during a follow-up of 30.6 +/- 6.1 months.
