ACURATE IDE: Transcatheter Replacement of Stenotic Aortic Valve Through Implantation of ACURATE in Subjects InDicatEd for TAVR
In Brief
A clinical study evaluating ACURATE neo2™ Transfemoral TAVR System, Medtronic CoreValve TAVR System, and 2 other interventions for Aortic Stenosis. Active but no longer recruiting, targeting 1,948 participants across 75 sites in 2 countries.
Detailed Summary
To evaluate safety and effectiveness of the ACURATE Transfemoral Aortic Valve System for transcatheter aortic valve replacement (TAVR) in subjects with severe native aortic stenosis who are indicated for TAVR. As of 28-May-2025, Boston Scientific Corporation (BSC) announced the voluntary global discontinuation of the ACURATE product platform, including both the ACURATE neo2 and ACURATE Prime Aortic Valve Systems. BSC will no longer pursue regulatory approval for the device in the U.S. or other unapproved geographies.

Timeline
Interventions
ACURATE neo2™ Transfemoral TAVR system: Support frame made of nitinol, supra-annular processed tri-leaflet porcine pericardial valve and an outer skirt to limit paravalvular regurgitation (manufactured by Boston Scientific Corporation, Marlborough, MA, USA).
Medtronic CoreValve Evolut R or Evolut PRO Transcatheter Aortic Valve Replacement (TAVR) System (or any future Corevalve iterations): The support frame is manufactured from nitinol, which has multilevel, self-expanding properties and is radiopaque. The bioprosthesis is manufactured by suturing valve leaflets and a skirt from porcine pericardium into a tri-leaflet configuration (manufactured by Medtronic CoreValve LLC, Santa Ana, USA).
Edwards SAPIEN 3 TAVR system (or any future SAPIEN iterations): balloon-expandable transcatheter aortic bioprosthesis, support frame made of cobalt-chromium, three leaflets constructed of processed bovine pericardial tissue and an outer polyethylene terephthalate (PET) sealing cuff to mitigate paravalvular regurgitation (manufactured by Edwards Lifesciences, Inc., Irvine, California, USA)
ACURATE Prime™ Transfemoral TAVR system: Support frame made of nitinol, supra-annular processed tri-leaflet porcine pericardial valve and an outer skirt to limit paravalvular regurgitation (manufactured by Boston Scientific Corporation, Marlborough, MA, USA).
