Outcomes and Impact of Device Iterations in Mitral Valve Transcatheter Edge-to-Edge Repair: The REPAIR Study
Authors' conclusion
Device iterations of the PASCAL system resulted in increasing rates of achieving MR reduction to ≤1+ at discharge, with stable and high technical success rates.
Study context
- Population

Main finding
As reported in the abstract
P < 0.001
- Overall MR ≤1+ (n = 1,397 of 2,085)
- 72%
Observational data: associations, not effects.
Secondary outcomes
Technical success
- Overall technical success (n = 2,099 of 2,165), similar across device iterations
- 97.0%
- Across iterations
- P = 0.290
MR durability (30 days, 1 year, 2 years)
- MR ≤1+ and ≤2+ slightly worsened, primarily in primary MR, with no differences across iterations
