Further study details as provided by Viacor:

Primary Outcome Measures:
  • percent of patients who remain free from device-related major adverse events: death, myocardial infarction, tamponade, emergent cardiac surgery [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • percent of implanted patients who maintain a sustained 1 grade reduction in mitral regurgitation and reduction in mitral anterior posterior dimension [ Time Frame: 30 days ]
  • improvement of clinical symptoms of heart failure as defined by percent of implanted patients who exhibit one of the following: decrease in NYHA class, improvement in Minnesota QOL survey, increase in 6 minute walk, improvement in VO2 max. [ Time Frame: 30 days ]

Enrollment: 4
Study Start Date: February 2007
