BACKGROUND: Before its voluntary recall, the mechanically expandable LOTUS Edge transcatheter heart valve (THV) offered a number of unique features, notably sealing against paravalvular leak (PVL) and the ability to be fully deployed, re-captured, and re-deployed.
CONCLUSIONS: In our experience, in patients with heavy LVOT calcium burden and/or bicuspid valves, the LOTUS Edge THV offered excellent seal against PVL. However, the high rates of periprocedural stroke and new PPM implantation were a concern. Copyright (c) 2021. Published by Elsevier Inc.
METHODS: We performed a detailed review of all patients at our institution who underwent transcatheter aortic valve replacement (TAVR) using the LOTUS Edge THV from 2019 to 2020. We describe procedural and in-hospital outcomes.
RESULTS: In brief, 59 patients underwent TAVR using the LOTUS Edge, of whom 18 were high-risk (most of whom had moderate or severe left ventricular outflow tract [LVOT] calcium), 36 were intermediate-risk enrolled in the REPRISE IV trial (one of whom had a bicuspid valve), and 5 were low-risk bicuspid patients enrolled in the LRT trial. Conduction disturbances were common (new left bundle branch block in 64.4%), with high rates of new permanent pacemaker (PPM) implantation across all risk groups (16.9%). Overall, stroke occurred in 11.9% of patients, and in 3/5 low-risk bicuspid patients, but occurred less frequently in patients with cerebral embolic protection.
