SAPIEN valve for percutaneous transcatheter pulmonary valve replacement without "pre-stenting": A multi-institutional experience.

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 ("pre-stenting").

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 pre-stent.
