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
Overview
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).
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.
Interventions
- Other Data collection on patient history and intraoperative results.
Data collection on patient history and intraoperative results.
Primary outcome measures
- Maximum value of Young's modulus [Time frame: Hour 1]
Secondary outcome measures (1)
- First histological evaluation [Time frame: Hour 1]
Eligibility criteria
