Primary Outcome Measures:
  • Freedom from MACE at 30 days post-procedure and quantitative MR reduction at 6 months [ Time Frame: 30 days to 6 months ]

Secondary Outcome Measures:
  • % of patients experiencing procedure or device-related adverse events [ Time Frame: 30 days to 6 months ]
  • Technical procedural success: % of patients maintaining a reduction of mitral annulus A/P dimension, sustained MR reduction, and decrease in left ventricular dimensions to specified degrees [ Time Frame: 6 months ]
  • Clinical status: % of treated patients exhibiting improvements in defined QoL parameters [ Time Frame: 6 months ]

Estimated Enrollment: 30
Study Start Date: October 2008
Estimated Study Completion Date: November 2015
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Patient is screened for study and given baseline assessments. Pending fulfillment of study eligibility criteria, patient is implanted with PTMA system.
Device: PTMA (Percutaneous Transvenous Mitral Annuloplasty) Implant
Percutaneous assessment from right or left subclavian vein, with PTMA implant in the coronary sinus, great cardiac vein, anterior interventricular vein.
