Brief Summary:

The Cardioband Transcatheter System (Cardioband) is indicated for the treatment of secondary (functional) mitral regurgitation (FMR). The Cardioband is a transcatheter system, deployed on the beating heart through a transseptal approach. The Cardioband is deployed along the posterior annulus of the mitral valve (MV) and is adjusted under trans-esophageal guidance on the beating heart. A CE mark study with 30 subjects has been completed and documented reduction of severity of mitral regurgitation (MR) and improvement in 6- minute walk test in subjects with moderate to severe MR.

Study objectives are to test the efficacy of the Cardioband in improving MR and heart failure symptoms in patients with symptomatic (New York Heart Association (NYHA) Class III-IVa), severe MR in the post-marketing setting, And to evaluate the safety of the Cardioband system in the post-marketing setting.

Mitral valve repair with Cardioband implanted via transcatheter procedure under transesophageal echocardiography (TEE) and fluoroscopy guidance




Primary Outcome Measures :
  1. Reduction in Severity of MR at 30 Days of at Least One Category on a 0-4 Scale. [ Time Frame: 30 days ]
    Percentage of Patients with Reduction in MR Severity of at least one grade at 30 days compared to baseline


Secondary Outcome Measures :
  1. Change in Distance Walked on 6 Minute Walk Test [ Time Frame: 6 months over Baseline ]
    Median distance in meters walked during 6 Minute Walk Test (6MWT) at 6 months compared to baseline

  2. Change in Mitral Regurgitation Severity [ Time Frame: 6, 12, and 24 months over baseline ]
    Mitral Regurgitation at 6, 12, and 24 months compared to baseline


Other Outcome Measures:
  1. Change in Distance Walked on 6 Minute Walk Test [ Time Frame: 12, and 24 months over baseline ]
    Median distance in meters walked during 6 Minute Walk Test (6MWT) at 12 and 24 months compared to baseline

  2. Change in Quality of Life (QoL) as Measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: 6, 12, and 24 months over baseline ]
    Median KCCQ Score. The KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. Scores range from 0-100, in which higher scores reflect better health status.

  3. Change in New York Heart Association (NYHA) Class [ Time Frame: 6, 12, and 24 months over baseline ]
    NYHA Class at 6, 12, and 24 months compared to baseline

  4. Change in Left Ventricular End Diastolic Volume (LVEDV) [ Time Frame: 6, 12, and 24 months over baseline ]
    Median LVEDV data, as measured by TTE at 6, 12, and 24 months compared to baseline

  5. Change in Left Ventricular End Systolic Volume (LVESV) [ Time Frame: 6, 12, and 24 months over baselines ]
    Median LVESV data, as measured by TTE at 6, 12, and 24 months compared to baseline

  6. Number of Participants With Device Success [ Time Frame: Discharge ]
    Device success is defined as deployment of the Cardioband, with MR reduction at hospital discharge.

  7. Number of Participants With Patient Success [ Time Frame: 6 and 12 months ]

    Individual patient success (measured at 6 months and 1 year) defined as device success and the following:

    • Discharged from index hospitalization
    • NYHA class improvement by at least 1 level from baseline

  8. Number of Days Alive and Out of Hospital [ Time Frame: 12 months ]
    Days alive and out of hospital due to major cardiovascular events at 1 year

  9. Freedom From All-cause Mortality and Major Adverse Events (AE) [ Time Frame: 30 days from implant procedure or hospital discharge, whichever is later. ]
    Freedom from all-cause mortality and major AE is defined as disabling stroke, myocardial infarction (MI) (peri-procedural or spontaneous), renal failure requiring dialysis, life-threatening bleeding, cardiac tamponade and device related cardiac surgical intervention at 30 days from the implant procedure or hospital discharge, whichever is later.

  10. Need for Urgent/Emergent Surgical Intervention [ Time Frame: 24 months ]
    Number of patients who undergo urgent/emergent surgical intervention post procedure
