|A Randomized Study of the MitraClip Device in Heart Failure Patients With Clinically Significant Functional Mitral Regurgitation
|A Randomized Study of the MitraClip Device in Heart Failure Patients With Clinically Significant Functional Mitral Regurgitation
This trial is a randomized study of the MitraClip device in heart failure patients with clinically significant functional mitral regurgitation. A hierarchical composite of all-cause mortality and recurrent heart failure hospitalizations is hypothesized to occur at a lower rate with the use of the MitraClip device in addition to optimal standard medical therapy compared to optimal standard of care therapy alone.
This study is a clinical evaluation of the safety and effectiveness of the MitraClip System in the treatment of clinically significant functional mitral regurgitation in patients with chronic heart failure. The objective is to further study the safety and effectiveness of the MitraClip System for the treatment of clinically significant functional mitral regurgitation in New York Heart Association Functional Class III or IV chronic heart failure patients.
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
The MitraClip System includes a MitraClip device, a Steerable Guide Catheter, and a MitraClip Delivery System that enables placement of the MitraClip device on the mitral valve leaflets
- Experimental: MitraClip Device
Subjects randomized to the Device group will undergo the MitraClip procedure in addition to optimal standard medical therapy
Intervention: Device: MitraClip
- No Intervention: Control
Subjects randomized to the Control group will receive optimal standard of care therapy alone

- Subject agrees to return for all required post-procedure follow-up visits
- The subject has been informed of the nature of the study and agrees to the study's provisions, including the possibility of randomization to the Control group, and has provided written informed consent as approved by the respective clinical site's Ethics Committee
- Mitral regurgitation is primarily due to degenerative disease of the mitral valve apparatus (Degenerative mitral regurgitation), as determined by transesophageal echocardiography
- Status 1 heart transplant or prior orthotopic heart transplantation
- Introduction of a new heart failure drug class within the last 4 weeks prior to randomization
- Cardiovascular hospitalization within the last 2 weeks immediately prior to randomization
- Evidence of acute coronary syndrome, transient ischemic attack or stroke within 90 days prior to randomization
- Any percutaneous cardiovascular intervention, carotid surgery, cardiovascular surgery or atrial fibrillation ablation within 90 days prior to randomization
- Implant of any rhythm management device (i.e., pacemaker, Cardiac Resynchronization Therapy with or without cardioverter-defibrillator (CRT or CRT-D), or Implantable Cardioverter Defibrillator (ICD) within 90 days prior to randomization, or revision of any implanted rhythm management device within 90 days prior to randomization
- Need for any cardiovascular surgery
- Mitral valve surgery is considered a therapeutic option for the subject
- Renal replacement therapy
- Uncontrolled hypertension (i.e., BP >180 mmHg systolic and/or >105 mmHg diastolic) or hypotension (i.e., BP <90 mmHg systolic)
- Unstable angina pectoris as judged by the investigator, other clinically significant uncorrected valvular disease or left ventricular outflow obstruction, obstructive cardiomyopathy, poorly controlled fast atrial fibrillation or flutter, poorly controlled symptomatic brady- or tachyarrhythmias
- 6MWT distance >450 meters
- Mitral Valve Area (MVA) by planimetry <4.0 cm2; if MVA by planimetry is not measurable, pressure half-time measurement is acceptable; MVA must be confirmed by the Echocardiography Core Laboratory
Leaflet anatomy which may preclude MitraClip device implantation, proper device positioning on the leaflets, or sufficient reduction in mitral regurgitation that may include:
- Evidence of calcification in the grasping area
- Presence of significant cleft in the grasping area
- Lack of both primary and secondary chordal support in the grasping area
- Prior mitral valve surgery
- Coaptation length ≤2 mm
- Leaflet mobility length <1 cm
- Presence of an IVC filter in the femoral vein that would interfere with the delivery catheter, or ipsilateral deep vein thrombosis (DVT) is present
- Contraindication to transseptal catheterization
- Subjects in whom transesophageal echocardiography is contraindicated
- Echocardiographic evidence of intracardiac mass, thrombus, or vegetation
- Active endocarditis or active rheumatic heart disease or leaflets degenerated from rheumatic disease (i.e., noncompliant, perforated)
Presence of any of the following:
- Severe aortic stenosis (aortic valve area <1.0 cm2) or severe aortic regurgitation
- Infiltrative cardiomyopathies (e.g., amyloidosis, hemochromatosis, sarcoidosis)
- Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or any other structural heart disease causing heart failure other than dilated cardiomyopathy of either ischemic or non-ischemic etiology
- Hemodynamic instability requiring inotropic support or mechanical heart circulatory support
- Active infections requiring current antibiotic therapy
- Known hypersensitivity or contraindication to procedural medications which cannot be adequately managed medically
- Severe right ventricular failure or severe tricuspid regurgitation
- History of bleeding diathesis or coagulopathy or subject who refuses blood transfusions
- Pregnant or planning pregnancy within next 12 months. Note: Female patients of childbearing potential need to have a negative pregnancy test performed within 14 days prior to randomization and be adherent to an accepted method of contraception
- Concurrent medical condition with a life expectancy of less than 12 months in the judgment of the investigator
- Currently participating in another therapeutic or interventional heart failure trial, or in any trial of an unapproved drug or device (Subjects participating in observational studies or registries may be considered as eligible)
- Subject belongs to a vulnerable population per investigator's judgment or subject has any kind of disorder that compromises his/her ability to give written informed consent and/or to comply with study procedures
