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 of mitral annulus anterior posterior dimension [ Time Frame: 30 days ]
  • improvement of clinical symptoms of heart failure as defined by percent of patients who exhibit one of the following: decrease in NYHA class, improvement in Minnesota QOL survey, increase in exercise capacity: 6 minute walk or VO2max [ Time Frame: 30 days ]

Enrollment: 12
Study Start Date: April 2006
Study Completion Date: November 2008
Primary Completion Date: April 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Patient is screened for study, and given baseline assessments. Patient receives a diagnostic PTMA assessment and if responsive, receives a PTMA implant.
Device: PTMA (Percutaneous Transvenous Mitral Annuloplasty) Implant
Percutaneous access from right or left subclavian vein with placement of assessment and placement of PTMA Implant into the coronary sinus, great cardiac vein. Device remains accessible from a subclavicular pocket.
