The ACURATE neo transcatheter aortic valve system.

The ACURATE neo transcatheter aortic valve system. Expert Rev Med Devices. 2018 Sep 26;: Authors: Choudhury T, Solomonica A, Bagur R Abstract INTRODUCTION: The field of transcatheter aortic valve implantation (TAVI) has seen an exponential expansion in available TAVI prostheses for the treatment of severe symptomatic aortic stenosis. Areas covered: The ACURATE neo (Boston Scientific, MA, USA) is a second-generation self-expanding transcatheter aortic valve system. The valve presents a supra-annular design, and comprises three stabilization arches for axial alignment, an upper-crown for capping the aortic annulus, and a lower-crown that is opened over the native aortic valve for full deployment. This device minimally protrudes into the left ventricular outflow-tract, thereby minimising the risk of coronary obstruction and conduction abnormalities. The Acurate neo can be delivered by transfemoral and transapical approaches with a unique "top-down" deployment. Information was gathered from published manuscripts obtained using standard databases (MEDLINE) and trial data presented at conferences. Expert commentary: Data from observational series show that TAVI with the Acurate neo is associated with low rates of all-cause mortality, paravalvular leak and permanent pacemaker requirement. Randomised data comparing the Acurate neo valve with contemporary valves and long-term durability data are awaited. Continuing modifications in device and...
