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.
