Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with severe mitral regurgitation who are considered inoperable or at high risk for surgical intervention.

Probably not a fit

Patients with mitral stenosis, rheumatic valve disease, or unsuitable anatomy for the procedure may not benefit from this study.

What this trial studies

This study evaluates the feasibility, safety, and performance of the HighLife 28mm Trans-Septal Transcatheter Mitral Valve Replacement System in patients with moderate-severe and severe mitral regurgitation who are at high risk for surgical treatment. It is a single-arm, prospective, multicenter, non-randomized, and open-label study. The investigational device includes a self-expanding mitral bioprosthesis and a sub-annular implant designed to stabilize the valve position. Patients will be assessed for eligibility based on specific anatomical and medical criteria.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive treatment option for patients with severe mitral regurgitation who are not candidates for traditional surgery.

How similar studies have gone: Other studies have explored transcatheter approaches for mitral valve replacement, showing promising results, but this specific device and methodology are relatively novel.

* Age ≥ 18 years
* Severe mitral regurgitation
* New York Heart Association (NYHA) Functional Class II, III or ambulatory IV.
* Patient is under maximally tolerated GDMT (incl. CRT) for at least 3 months
* Multidisciplinary Heart Team consensus that the patient is inoperable or at high-risk for surgical repair/replacement due to significant co-morbid conditions
* Multidisciplinary Heart Team consensus that the patient is not a suitable candidate for other approved percutaneous repair therapy due to anatomical or medical conditions
* Patient meets the anatomical criteria for HighLife valve sizing as determined by CT and TEE

Main Exclusion Criteria:

* Mitral stenosis
* Rheumatic valve disease
* Severe calcifications of the mitral annulus and/or mitral leaflets
