In Vivo Computed Tomography Sizing for Redo–Transcatheter Aortic Valve Replacement in Evolut Valves: Impact on Sizing, Feasibility, and Prosthesis-Patient Mismatch

SAPIEN3 (S3) is a ubiquitous redo-transcatheter aortic valve (TAV) replacement alternative for degenerated Evolut valves, but S3 sizing for S3-in-Evolut remains unclear. We sought to compare the impact of in vivo computed tomography (CT)-sizing on redo-TAV feasibility for S3-in-Evolut with traditional bench-sizing.
