N2 - OBJECTIVES: This study reports an international experience using the transfemoral ACURATE neo transcatheter heart valve (Boston Scientific, Marlborough, Massachusetts) for the treatment of degenerated surgical aortic bioprostheses.BACKGROUND: Transcatheter valve-in-valve procedures have emerged as an alternative to redo surgery. Supra-annular prostheses might be particularly useful in this indication.METHODS: This is an international multicenter analysis including 85 patients from 14 centers in Europe and Canada undergoing an ACURATE neo valve-in-valve procedure from March 2015 to February 2019.RESULTS: Internal diameter of the degenerated bioprosthesis was 20.3 ± 2.1 mm. Prosthesis size S was used in 70 (82%) procedures. The median depth of implantation was 3 mm and the upper crown of the ACURATE neo was positioned above the stent posts of the degenerated bioprosthesis in 54 (64%) and inside in 31 (36%). Mean transvalvular gradient before discharge was significantly lower if the upper crown was above the degenerated bioprosthesis (13.7 ± 5.9 mm Hg vs. 19.5 ± 10.0 mm Hg; p = 0.001). However, a high position of the ACURATE neo resulted in embolization in 1 patient, conversion to open-heart surgery in 1, and need for reintervention due to transcatheter heart valve failure within the first 18 months of follow-up in 4.CONCLUSIONS: This early experience shows that a high implantation of the ACURATE neo with the upper crown above the stent posts of the degenerated bioprosthesis resulted in lower mean transvalvular gradients but a higher rate of malpositioning and early valve degeneration.
