AIMS: To assess outcomes with a new fully repositionable and retrievable valve for transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: The Lotus Aortic Valve System is designed to facilitate precise positioning and minimise paravalvular regurgitation. REPRISE I enrolled symptomatic, high-surgical-risk patients with severe aortic stenosis. The primary endpoint (clinical procedural success) included successful implantation without major adverse cardiovascular or cerebrovascular events (MACCE). In all patients (N=11) the first Lotus Valve was successfully deployed. Partial resheathing to facilitate accurate placement was attempted and successfully performed in four patients; non..
