Brief Summary
Study to assess mitral valve therapy for advanced insufficiency of functional or ischemic origin in patients with moderate-to-severe mitral regurgitation (MR) of primarily functional pathology and reduced left ventricular function considered to be at high surgical risk

Outcome Measures
Primary Outcomes (1)
Composite of death, rehospitalisation for heart failure, reintervention (repeat operation or repeat intervention), assist device implantation and stroke (whatever is first) 12 months post intervention; equivalently "freedom from event"
Composite of death, rehospitalisation for heart failure, reintervention (repeat operation or repeat intervention), assist device implantation and stroke (whatever is first) 12 months post intervention; equivalently "freedom from event"
12 months post intervention
Secondary Outcomes (8)

12 months post intervention
Change in 6 Minute Walk Test distance from baseline to 12 month post intervention (difference "12 months minus baseline
12 months post intervention
Change in NYHA functional class from baseline to 12 months post intervention
12 months post intervention
Change in Minnesota Living with Heart Failure Questionnaire (MLHFQ) score from baseline to 12 months post intervention
12 months post intervention
Echocardiographic assessment of left ventricular remodelling
12 months post intervention
- +3 more secondary outcomes
Study Arms (2)
Percutaneous mitral valve repair (MitraClip system )
EXPERIMENTALPercutaneous mitral valve repair (simultaneous left atrial and ventricular pressure assessment suggested) with MitraClip system (Abbott)
Mitral valve surgery
ACTIVE COMPARATORMitral valve surgery or mitral valve replacement (technique and access at the discretion of the participating surgical center, MACE procedure and tricuspid annuloplasty possible)
Interventions
Valve repair with the MitraClip system (Abbott Vascular, Menlo Park, USA) consists of a steerable guide through which a Clip Delivery System is advanced to the left atrium.
Mitral valve surgery or mitral valve replacement (technique and access at the discretion of the participating surgical center, MACE procedure and tricuspid annuloplasty possible)
Eligibility Criteria
You may qualify if:
- Clinically significant mitral regurgitation of primarily functional pathology
- Left Ventricular Ejection Fraction (LVEF) ≥20% determined by echocardiography
- High surgical risk as determined by Heart Team consensus
- Documented New York Heart Association Class II to Class IV heart failure, despite optimal standard of care therapy
- Written informed consent in accordance with Good Clinical Practice (GCP) and local legislation
You may not qualify if:
- Echocardiographic evaluation not available or not suitable for analysis at baseline
- Severe tricuspid regurgitation according to current guidelines5
- Other severe valve disorders requiring intervention according to current
- Coronary revascularization or cardiac resynchronization (CRT) device implantation within 1 month before the procedure
- Patient not amenable for mitral valve surgery/ percutaneous mitral valve reconstruction as judged by Heart Team
- Key information from patients (e.g. NYHA, MR grade) not available
