    AbstractThe incidence of embolic ischemic cerebral events during transcatheter aortic valve implantation remains high. The effects range from clinically silent embolic lesions in the brain to severe disabling stroke. Memory loss and other functional neurocognitive impairment are a direct result of embolic strokes. The TriGuard embolic deflection device is a nitinol frame filter that is placed across all three aortic cerebral vessel ostia to prevent particles from entering the brain circulation during the procedure. The results of clinical studies suggest that this procedure can lead to a reduction of embolic events, and an improvement of neurocognitive function when compared with unprotected transcatheter aortic valve implantation.
