  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.

What is the study measuring?
