OBJECTIVE: We describe our medium-term outcomes for @entity3657 stenting in adults with @entity299 . BACKGROUND: Improved outcomes in @entity299 have lead to the evolution of transcatheter therapies in adults aimed at maintaining normal hemodynamics. Stenting for pulmonary artery narrowing is effective in @entity1 , however little is known about outcomes in adults. METHODS: Retrospective data analysis and follow-up review of our complete experience with @entity3657 stenting in adults. RESULTS: Over a 9-year period we carried out 15 procedures, implanting 23 stents (11-left pulmonary artery) in the pulmonary arteries of 12 adult @entity1 (7 female). Eleven @entity1 had previous cardiac surgery. Median age at implantation was 32.5 years (range, 18.7-56.7 years) with median weight of 71.3 kg (range, 44.5-95 kg). Six @entity1 underwent bilateral pulmonary artery stenting. Median procedure time was 140 minutes (range, 76-263 minutes) and 4 @entity1 had other interventions performed during the same procedure. Median systolic pressure gradient across the narrowing's of 24 mmHg (range, 11-61 mmHg) was reduced to 3 mmHg (range, 0-17 mmHg) postprocedure (P < 0.001). Three @entity1 had @entity697 , one of whom required surgical removal. No @entity439 formation or significant stent @entity174 have been noted on median follow-up of 27.4 months (range, 1-97 months). Two @entity1 required reintervention with further stent implantation. CONCLUSIONS: Pulmonary artery stenting provides effective relief of narrowing in adults with @entity299 . Bilateral and/or multiple stenting are often required. @entity887 may occur particularly in @entity1 with associated significant @entity338 . (J Interven Cardiol 2011;24:373-377).
