Early Feasibility Experience of Posterior Leaflet Restoration to Reduce Mitral Regurgitation Using the MRace Implant Brazil (EXPLORE MRace - BR)
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 10 patients at one (1) center in Brazil.
• 18 years of age or older
• Greater than moderate mitral regurgitation (Grade 3+ or higher) as confirmed by transesophageal echocardiography (TEE) within 90 days prior to study procedure
• Patient must present with an STS Score less than 10%
• High surgical risk for conventional mitral repair or replacement due to morphological criteria (e.g. leaflet or annulus calcifications), but operable, as assessed by the local heart team comprised of a cardiac surgeon experienced in mitral valve surgery and a cardiologist experienced in treating mitral valve disease and heart failure
• New York Heart Association (NYHA) Functional Class III or IV
• Patient willing to participate in study and provide signed IRB/EC-approved informed consent
• Treating physician and patient agree that patient is able to return for all required post-procedure follow-up visits
