Arm Intervention/treatment
Multi-center, prospective, single-arm study
To assess the safety and performance of the GDS Accucinch System when used percutaneously to reduce functional mitral regurgitation.
Device: GDS Accucinch System
Percutaneous Coronary Intervention

Primary Outcome Measures :
  1. Procedural Success [ Time Frame: 72 hours post-procedure ]
    Successful use and implantation of an Accucinch System without Major Adverse Events (MAE) defined as the occurrence of any of the following: All-cause mortality, Device and/or procedure-related death; Peri-procedural myocardial infarction (MI) < or equal to 72 hrs after index procedure; Major stroke; Urgent or emergent conversion to surgery or repeat procedure (surgical or interventional therapy) for mitral valve or heart failure related deterioration; Left ventricular perforation; Major vascular complications; Major bleeding (including cardiac tamponade)

  2. Device Success [ Time Frame: 24 hours post-procedure ]
    Successful vascular access, delivery, and retrieval of the delivery system; Ability to establish access to the sub-annular groove, to deploy the Anchors, and the Anchor Links, to apply tension to the Cinch Cable, to reshape the mitral annulus, to deploy the Lock, and to cut the Cinch Cable; Intended performance of the Accucinch System measured by TTE acutely post-cinch with a reduction of MR by at least one grade

  3. Clinical Safety Measures [ Time Frame: 7 day post procedure ]
    Defined as freedom from MAE at discharge or 7 days post-procedure, whichever comes first; Safety measures will be reviewed and adjudicated by an independent clinical events committee (CEC); Echocardiographic measures will be assessed by an independent echocardiography core laboratory

Secondary Outcome Measures :
  1. Clinical Measure [ Time Frame: 30 day post-procedure ]
    NYHA Class improvement of at lease one score from baseline

  2. Echocardiographic Measures - Composite [ Time Frame: 30 days post-procedure ]
    Mitral Valve Measures: One grade reduction in MR (e.g. 3+ to 2+), or; Reduction in PISA EROA at least 25% from baseline, or; Reduction in Regurgitant Volume at least 25% Left Ventricular Measures: Reduction in Left Ventricular size (Left Ventricular End Diastolic Dimension - LVEDD) at least 5% from baseline, or: Reduction in Left Ventricular volume (Left Ventricular End Diastolic Volume -LVEDV) at least 5%, or Increase in ejection fraction (LVEF) at least 10% from baseline Left Atrial Measures: Left atrial volume index (biplane area-length method). The above echocardiographic measures will be assessed by an independent core laboratory

  3. Clinical Measure [ Time Frame: 30 day post-procedure ]
    6-minute walk test compared to baseline

  4. Clinical Measure [ Time Frame: 30 day post-procedure ]
    Quality of Life (KCCQ Questionnaire) compared to baseline

Other Outcome Measures:
  1. Additional Measures - Composite [ Time Frame: Collected at baseline, peri- and post-procedure, discharge or 7-days (whichever comes first) 30-day, 3, 6, and 12 months and at 2 and 3 years post procedure ]
    Safety measures (adjudicated by an independent Clinical Events Committee): Mortality: all-cause, cardiovascular, and non-cardiovascular; Spontaneous Myocardial Infarction (>72 hrs post-index procedure); Major and life-threatening bleeding; Major stroke: disabling and non-disabling; Major vascular complication (access site, non-access site); Acute Kidney Injury (< or equal to 72 hrs post-procedure): based on the modified RIFLE Stage 3 (including renal replacement therapy), Stage 2, and Stage 1; Failure of current therapy for functional mitral regurgitation requiring re-hospitalization or prolonged hospitalization for FMR-related symptoms and worsening heart failure with NYHA class III or IV, or requiring conversion to surgery; Anchor(s) migration or Anchor(s) dislocation (as assessed by fluoroscopic images or CT) (when applicable)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age > 18 years

  • Prior surgical, transcatheter, or percutaneous mitral valve intervention or mitral valve prosthesis
  • Subject has untreated coronary artery disease, which in the opinion of the treating physician and/or heart team, is clinically significant and requires revascularization
