Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients who voluntarily participate and sign the informed consent form and can cooperate with the completion of the entire trial process;
• Age ≥ 18 years old;
• Moderate-severe or severe mitral regurgitation (≥3+); Note 1: Patients with ischemic or non-ischemic heart disease induced symptomatic secondary mitral regurgitation as the primary cause must be treated for at least 1 month after optimal guideline medical therapy (GDMT). Echocardiography should be performed 3 months after cardiac resynchronization therapy and 1 month after coronary revascularization to assess the degree of regurgitation.
• Note 2: For patients with primary mitral regurgitation, the multidisciplinary cardiac team of the research center needs to use a standard scoring system, considering multiple factors such as complications, frailty, and disability, ensuring the enrolled with a high risk of surgery.
• Patients with New York Heart Association (NYHA) functional ratings are Class II, III, or ambulatory Class IV;
• Anatomically appropriate for treatment with the HighLife Transcatheter Mitral Valve Replacement System.

You may not qualify if…

• Patients had any stroke/TIA within 30 days;
• Patients with severe symptomatic bilateral carotid stenosis (>70% stenosis on non-invasive imaging);
• Patients with active infection requiring antibiotic therapy;
• Patients with active ulcer or gastrointestinal bleeding within the past 3 months;
• Patients with history of coagulopathy or refuse future blood transfusion;
• Patients unable to undergo transesophageal echocardiography (TEE);
• Patients who are pregnant or breastfeeding, or planning to have children within 12 months;
• Patients who are unable to adhere to the follow-up schedule and complete the examination;
• Patients enrolled in other clinical studies and within the follow-up period;
• Patients with known allergies to device components or contrast agents;
• Patients unable to receive anticoagulant or antiplatelet therapy;
• Patients with a life expectancy of less than 12 months due to non-cardiac disease;
• Patients requiring emergency surgical treatment;
• Patients scheduled for cardiac surgery within 12 months;
• Patients with an inappropriate mitral annulus or leaflet size (<30 mm and >45 mm);
• Patients with moderate or above mitral stenosis;
• Flail mitral leaflets, or moderate to severe mitral valve prolapse;
• Patients with severe hepatic or renal insufficiency;
• Patients with severe calcification of the mitral annulus and/or mitral leaflets;
• Patients with history of mitral valve surgery or interventional therapy, or left atrial appendage occlusion device;
• Patients had acute myocardial infarction (MI) (Q-wave MI, or non-Q-wave MI, with CK-MB twice the normal and/or T-MB) within the past 1 month;
• Patients with untreated symptomatic coronary lesions requiring revascularization;
• Patients with untreated severe aortic stenosis and severe aortic regurgitation;
• Patients with aortic valve prosthesis;
• Patients with severe tricuspid valve lesions requiring surgical intervention;
