About this study
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
There is no information in the literature on the mechanobiological characteristics of mitral valve chords in living humans. All examinations were carried out on tissues taken from animals, either from cadavers or from frozen human tissues. The objective is to determine mechanobiological and histological characteristics of the mitral valve chords in living humans, as well as to compare differences in elasticity in different groups (Group A: patients with mitral valve prolapse versus Group B: patients with restrictive ischemic mitral valve).
Read the detailed description
The prospective study will be conducted on 20 patients, who will be selected consecutively without randomization. The inclusion and exclusion criteria are determined.
The harvested tissue will not be frozen and will kept in natural conditions as close as possible.

Questions about this trial
What is this clinical trial studying?
An observational study of Mitral Valve Disease, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 6 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Andranik PETROSYAN, MD ((0)477829505 ext. +33, andranik.petrosyan@chu-st-etienne.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum value of Young's modulus (time frame: Hour 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jan 2025; AzTrials last refreshed its copy on 8 Nov 2026.
