Experimental: Edwards PASCAL Transcatheter Mitral Valve Repair System |
Device: Mitral Valve Repair
Minimal Invasive Transcatheter Mitral Valve Repair |
- Composite of major adverse events (MAE) defined as cardiovascular mortality, stroke, myocardial infarction, new need for renal replacement therapy, severe bleeding and re-intervention for study device related complications at 30 days. [ Time Frame: The primary endpoint will be assessed at 30 days. ]
- Mitral regurgitation reduction [ Time Frame: 30 days, 6 months, 1 year ]
- All-cause mortality [ Time Frame: 30 days , 6 months, 1 year ]
- Recurrent heart failure hospitalization [ Time Frame: 30 days , 6 months, 1 year ]
- Change in Six Minute Walk Test (6MWT) distance [ Time Frame: 6 months and 1 year ]

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Signed and dated IRB/ethics committee approved study consent form prior to study related procedures
- Eighteen (18) years of age or older
- New York Heart Association (NYHA) Functional Class II-IVa heart failure despite optimal medical therapy
- Candidacy for surgical mitral valve repair or replacement determined by Heart Team evaluation
- Clinically significant mitral regurgitation (moderate-to-severe or severe mitral regurgitation) confirmed by transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE).
- The primary regurgitant jet is non-commissural. If a secondary jet exists, it must be considered clinically insignificant.
- Mitral valve area (MVA) ≥ 4.0 cm² as measured by planimetry. If MVA by planimetry is not measurable, pressure half-time measurement is acceptable.
Exclusion Criteria:
- Patient in whom a TEE is contraindicated or screening TEE is unsuccessful
- Leaflet anatomy which may preclude PASCAL device implantation, proper device positioning on the leaflets, or sufficient reduction in mitral regurgitation.
- Mitral valve area (MVA) < 4.0 cm² as measured by planimetry (If MVA by planimetry is not measurable, PHT measurement is acceptable)
- Echocardiographic evidence of intracardiac mass, thrombus, or vegetation
- Physical evidence of right sided congestive heart failure and echocardiographic evidence of severe right ventricular dysfunction
- Concurrent medical condition with a life expectancy of less than 12 months in the judgment of the Investigator
- Patient is currently participating or has participated in another investigational drug or device clinical study where the primary study endpoint was not reached at time of enrollment
- Patient is under guardianship
