Evaluating the elasticity of the mitral valve in living humans
Official title: Evaluation of the Elasticity of the Mitral Valve Chordae by Uniaxial Traction in the Context of Mitral Valve Regurgitation With a Comparison of the Results: Mitral Valve Prolapse vs Restriction of Mitral Valve Movement
Run by Centre Hospitalier Universitaire de Saint Etienne · NCT06153563 · Data updated 2026-11-12
This study is trying to see how stretchy the mitral valve chords are in people who need mitral valve replacement, comparing those with mitral valve prolapse to those with a different heart condition.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients over 45 years old scheduled for mitral valve replacement.
✕Probably not a fit
Patients with mitral calcification, rheumatic disease, infections, or those undergoing redo surgery on the mitral valve may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study aims to investigate the mechanobiological and histological characteristics of mitral valve chords in living humans, a topic that has not been previously explored in the literature. The study will involve 20 patients scheduled for mitral valve replacement, who will be grouped based on their specific mitral valve conditions. Data will be collected on patient history and intraoperative results, with a focus on comparing the elasticity of mitral valve chords between patients with mitral valve prolapse and those with restrictive ischemic mitral valve. The harvested tissue will be preserved in natural conditions to ensure accurate analysis.
Why it matters
Potential benefit: If successful, this study could enhance the understanding of mitral valve disease and improve surgical outcomes for patients undergoing mitral valve replacement.
How similar studies have gone: This study addresses a novel area of research, as previous examinations have primarily focused on animal tissues or frozen human samples, making it an untested approach in living humans.
