An interventional study of Transcatheter mitral valve repair (MRace Implant and Delivery System) in Mitral Valve Disease, sponsored by Polares Medical SA. Recruiting at 4 sites in Georgia. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-01.
Sponsored by Polares Medical SA · Not applicable, Interventional, and Treatment
An early feasibility study to evaluate the safety and feasibility of the MRace Implant and Delivery System to treat severe mitral regurgitation and to gather preliminary data on its performance thereby providing guidance for future clinical development. The study is a single-arm registry with the last follow-up visit at 5 years post-intervention. The study will enroll up to 100 patients at four (4) centers in the Republic of Georgia.
Percutaneous approaches to treat MR promise to provide a sufficient reduction in MR without the risks typically associated with open heart surgery. Furthermore there is an unmet clinical need for patients with severe MR who are refused or denied surgery due to high risk. Percutaneous therapy provides a novel alternative treatment option for these patients with the aim of reducing morbidity and mortality over and above current medical therapy. The Polares Medical MRace Implant and Delivery System is a catheter-based technology designed to permanently implant a prosthesis using a transvenous / transseptal approach to augment the posterior mitral valve leaflet and improve coaptation with the anterior leaflet. Approved edge-to-edge repair has already been shown to be a viable alternative for high risk MR patients. However treatment with these devices is limited to specific anatomies and often requires multiple devices which increases clinical risk, adds to procedural time, and can result in residual MR. The MRace Implant and Delivery System has been designed to overcome and mitigate some of these shortfalls

The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
