Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Single-Center, Open-Label, Single-Arm Pilot Study of the Safety and Efficacy of the Percutaneous Transvenous Mitral Annuloplasty Implantable Device Used to Reduce Mitral Valve Regurgitation.

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 MR and reduction of mitral annulus anterior posterior dimension [ Time Frame: 30 days ]
  • percent of implanted patients who exhibit improvement of clinical symptoms as one of the following: decrease in NYHA class, improvement of Minnesota QOL survey, increase exercise capacity 6 minute walk or improvement in VO2 max [ Time Frame: 30 days ]

Enrollment: 5
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, diagnostic assessment, then placement of the PTMA implant in the coronary sinus, great cardiac vein.
