First dutch experience of the accurate neo self-expanding supra-annular valve for valve-in-valve transcatheter aortic valve implantation

We describe the first two cases of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) using Accurate Neo device in the Netherlands. A 73-year-old man underwent transfemoral ViV-TAVI for severe stenosis in his 25-mm Carpentier-Edwards Perimount bioprosthesis. After balloon predilatation, a mediumsize Accurate Neo was advanced to the bioprosthetic annulus. First, its upper part was released with the upper crowns positioned below the superior margin of the pre-existing bioprosthesis (Fig. 1a; [1]). Next, the device was deployed by releasing the lower crowns without ventricular pacing (Movie-1). The results were excellent. A 79-year-old man underwent transfemoral ViV-TAVI for severe regurgitation of his 27-mmMosaic bioprosthesis. A small-size Accurate Neo was deployed with its upper crowns positioned along the eyelets of the bioprosthesis (Fig. 1b). After balloon postdilatation, a paravalvular leak was reduced to trace.
