Key result
Implantation of the Sapien XT/3 transcatheter valve in the pulmonary position without a pre-stent was successful, simplifying the procedure and reducing radiation burden.
Why the study?
Pre-stenting is widely used for TPVI, but the strong balloon expandable design of the Edwards Sapien valve might obviate the need for a pre-stent.
Does transcatheter pulmonary valve implantation using the Sapien valve without a pre-stent result in successful implantation in patients with dysfunctional RV-PA conduits or pulmonary valves?
Observational
No
Does transcatheter pulmonary valve implantation using the Sapien valve without a pre-stent result in successful implantation in patients with dysfunctional RV-PA conduits or pulmonary valves?
The Edwards Sapien valve can be successfully implanted in the pulmonary position without a pre-stent, potentially simplifying the procedure and reducing radiation exposure.
May simplify pulmonary valve procedures; hypothesis-generating and requires prospective validation before practice change.
BACKGROUND: Pre-stenting is a widely used technique for transcatheter pulmonary valve implantation (TPVI). For the Melody valve a pre-stent creates a reliable and solid landing zone. In contrast to the Melody valve, the Edwards Sapien valve consists of a strong balloon expandable stent designed for implantation in the aortic position. The usage of a Sapien valve in pulmonary position might therefore obviate the need of a pre-stent. METHODS: This retrospective, single centre study reviewed the procedural outcomes of patients receiving the Sapien XT transcatheter valve in pulmonary position without prior implantation of a pre-stent. All consecutive patients with dysfunctional right ventricle to pulmonary artery (RV-PA) conduits or with dysfunctional pulmonary valve treated at the German Heart Centre in Munich were included in this study. RESULTS: We report on successful implantation of a Sapien XT/3 without usage of a pre-stent. CONCLUSIONS: Abandonment of the pre-stent simplified the procedure and reduces the radiation burden for the patients.

Tanase et al. (2019) conducted an observational in Dysfunctional right ventricle to pulmonary artery (RV-PA) conduits or dysfunctional pulmonary valve. Sapien XT/3 transcatheter valve implantation without a pre-stent was evaluated on Procedural outcomes (successful implantation). Implantation of the Sapien XT/3 transcatheter valve in the pulmonary position without a pre-stent was successful, simplifying the procedure and reducing radiation burden.
