Eligibility Criteria
You may qualify if:
- Age \> 21 years at time of enrollment
- Patient has provided informed consent, is willing and capable of participating in all testing, and agrees to return for all required post-procedure follow-up visits
- Moderate-to-severe or severe (MR ≥ 3+) functional (secondary) mitral valve regurgitation
- Symptomatic with mitral regurgitation (NYHA Class II, III, or ambulatory IV) despite maximally-tolerated guideline-directed medical therapy (GDMT) as determined by the local multidisciplinary Heart Team
- Patient is suitable for transcatheter mitral valve repair as determined by the local multidisciplinary Heart Team and confirmed by the Eligibility Committee
You may not qualify if:
- Estimated life expectancy of less than 12 months
- Women who are pregnant, lactating, or planning to become pregnant during the clinical study. Women of child-bearing potential must have negative pregnancy test result within 2 weeks prior to the procedure
- Left Ventricular Ejection Fraction (LVEF) \< 20%
- Left ventricular end diastolic diameter (LVEDD) \> 75 mm
- Acute hemodynamic decompensation
- Known hypersensitivity or contraindications to necessary and routine medications including contrast compounds or components used in the CARLEN System that cannot be successfully pre-medicated, including nitinol, an alloy of nickel and titanium
- Contraindicated for transesophageal echo (TEE)
- Presence of other anatomical characteristics and/or significant comorbidities that in the judgement of the Investigator or Eligibility Committee precludes the subject from participation
- Aortic valve disease requiring intervention or intervention
- Severe or greater tricuspid regurgitation
- Severe right ventricular dysfunction
- Severe pulmonary hypertension
- Presence of significant congenital heart disease
- Planned or scheduled cardiac surgery within next 12 months
- Endocarditis within last 90 days
- +1 more criteria
