Why is this study important?
- Proof of concept of new technique for direct reduction in mitral valve annular area.
- Identified a potential new adjunctive therapy to current TEER procedures.
What question was this study supposed to answer?
- Previous attempts at annular reduction using the coronary sinus have been disappointing.
- This study demonstrated the technical feasibility of intramyocardial device delivery.
What did the study show?
- Procedural success in a small group (n=19) of HFpEF and HFrEF patients with persistent MR after TEER.
- The ability to evaluate the procedural success and potential complications and stop the procedure without complications.
- Improvement in both physiologic parameters and clinical functional status.
