Eligibility
Inclusion criteria
Inclusion criteria: 1. Age >= 18 years old; 2. Echocardiography confirms moderate-to-severe (3+) or severe (4+) functional mitral regurgitation; 3. Patients with a history of hospitalization for heart failure within the past six months, who still exhibit clinical symptoms of heart failure (HF) after one month of treatment with the maximum dosage of guideline-directed medical therapy (GDMT) (including CRT therapy, if necessary), and have a New York Heart Association (NYHA) functional classification of II-IV; 4. The heart team at the local clinical trial institution has assessed the patient as high-risk for surgical intervention, making surgery unsuitable. The patient can only rely on medication; 5. After the researchers evaluated the anatomical structure of the mitral valve as suitable, the experimental device can be used for mitral annuloplasty; 6. The subjects or their guardians are able to understand the purpose of the trial, voluntarily participate and sign a written informed consent form, and are able to undergo follow-up visits as required by the protocol.
