- Moderate-to-severe or severe MR (3+) despite optimal guideline-directed medical therapy (GDMT) as determined by an independent Echo Core Lab.
- Unsuitable for surgery and Transcatheter Edge-toEdge Repair (TEER) as determined by the local site Heart Team.
Exclusion criteria
- (Abbreviated List):
- Inability to understand the trial or a history of non-compliance with medical advice.
- Inability to provide signed Informed Consent Form (ICF).
- History of any cognitive or mental health status that would interfere with participation in the trial.
- Currently enrolled in any other pre-approval investigational trial (does not apply to long-term post-market trials unless these trials might clinically interfere with the current trial endpoints (e.g., limit use of trial-required medication, etc.)).
- Female subjects who are pregnant or planning to become pregnant within the trial period.
- Known hypersensitivity or contraindication to heparin, or warfarin without adequate alternative medications.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
