Association of Self-Expanding Valves with Increased Capture of Larger Debris by Cerebral Protection System in Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis.

Background: Mixed evidence exists regarding stroke rates when comparing self-expanding valves (SEVs) to balloon-expandable valves (BEVs) in transcatheter aortic valve replacement (TAVR). This study investigates the debris captured by the SENTINEL cerebral protection system (CPS) during TAVR.

Methods: Seventy-five consecutive patients who underwent TAVR with CPS from March to December 2023 were recruited.
