Key result
Lotus Valve enables full re-sheathing and retrieval for TAVR size change in first reported case.
Why the study?
New TAVR devices with novel design features may overcome some complications associated with transcatheter aortic valve replacement.
Demonstrates the feasibility of fully re-sheathing and retrieving the Lotus Valve during TAVR to allow for prosthesis size adjustment.
Supports technical feasibility of repositionable TAVR; leaves open safety and efficacy questions for routine use.
While transcatheter aortic valve replacement (TAVR) is an accepted treatment modality in appropriately selected patients there remain modest complication rates. New TAVR devices, through novel design features, may overcome some of these complications. We present the first case of full re-sheathing and retrieval of a Lotus Valve to facilitate a change in prosthesis size.

Gooley et al. (2013) studied this question. The Lotus Valve, a novel TAVR device, allowed for full re-sheathing and retrieval to facilitate a change in prosthesis size in a first-reported clinical case.
