Objectives: To describe a multicenter experience of percutaneous transcatheter pulmonary valve replacement (TPVR) using the Edwards SAPIEN S3 valve without the use of a prior stent ("prestenting").Background: The SAPIEN S3 and XT valves have durable cobalt-chromium stent frames which may allow for TPVR in large diameter dysfunctional right ventricular outflow tracts (RVOTs) without pre-stenting the landing zone.Methods: A retrospective review was performed of all patients with Congenital Heart Disease and dysfunctional RVOT who underwent TPVR using the SAPIEN valve without the use of a prestent. Imaging data, procedural elements, and clinical follow-up data were collected to evaluate short and intermediate-term results.

TPVR in the nRVOT was feasible and safe. However, nearly half the patients presenting for catheterization did not undergo TPV implantation, mainly because of prohibitively large nRVOT size. Improved understanding of magnetic resonance imaging data and availability of larger devices may improve the success rate for nRVOT TPVR.
