Outcome Measures

Primary Outcomes (1)

  • Change in NYHA classification from Baseline to 5 years

    The New York Heart Association (NYHA) functional classification system relates symptoms to everyday activities and the patient's quality of life. Class I. Patients with cardiac disease but without resulting limitation of physical activity. Class II. Patients with cardiac disease resulting in slight limitation of physical activity. They are comfortable at rest. Class III. Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Class IV. Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest.

    Baseline compared to 1 and 5 years

Study Arms (1)

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is \>/= 21 years old.
  • Presence of severe degenerative mitral regurgitation with mid-segment posterior leaflet prolapse (without commissural involvement) by echocardiographic study.
  • Mitral leaflet coaptation surface sufficient to reduce mitral regurgitation without undue leaflet tension, based on the judgment of the Echocardiographic Core Lab.
  • Patient competent to sign informed consent and able to return for follow-up and is capable of participating in all testing associated with this clinical investigation.

You may not qualify if:

  • Patients will be excluded if ANY of the following criteria apply:
  • Functional mitral regurgitation (FMR).
  • Evidence of anterior or bileaflet prolapse.
  • Severe mitral annular calcification (MAC).
  • Moderate or greater leaflet calcification.
  • Fragile or thinning apex (e.g. LV aneurysm).
  • Have undergone cardiac or peripheral vascular procedures within 30 days prior to the trial procedure.
  • Planned cardiac or peripheral vascular procedures within 30 days after the trial procedure.
  • Requirement for concomitant cardiac surgery.
  • Severe pulmonary hypertension (pulmonary artery systolic pressure \> 60mmHg).
  • Severe aortic stenosis or insufficiency.
  • Severe tricuspid regurgitation. (Patients with mild or moderate tricuspid regurgitation are not excluded.)
  • Left ventricular ejection fraction (LVEF) \<30%, or severely impaired right ventricular dysfunction as measured by the core lab.
  • Any history of endocarditis.
  • Contraindication to cardiac surgery, including hostile chest or history of mediastinal radiation.
  • +20 more criteria
