Abbott Receives FDA Approval for Tendyne™, First-of-Its-Kind Device to Replace the Mitral Valve Without Open-Heart Surgery
- Abbott received FDA approval on May 27, 2025, for its Tendyne TMVR system to treat severe mitral annular calcification in the United States.
- This approval follows nearly a decade of development to address patients with high surgical risk whose valves cannot be repaired by existing devices like MitraClip.
- The Tendyne valve is a self-expanding, repositionable device delivered via a small chest incision, available in multiple sizes to fit various anatomies and replace valves impaired by mitral regurgitation or stenosis.
- Dr. Paul Sorajja emphasized that Tendyne offers an important therapeutic option for patients with MAC who are often unsuitable for conventional surgery, improving their symptoms and overall daily functioning.
- The approval expands Abbott's structural heart portfolio with a minimally invasive option for patients who are poor candidates for open-heart surgery, potentially improving treatment outcomes in mitral valve disease.
