Percutaneous Repair of Moderate-to-Severe or Severe Functional Mitral Regurgitation in Patients with Symptomatic Heart Failure: Baseline Characteristics of Patients in the RESHAPE-HF2 Trial and Comparison to COAPT and MITRA-FR Trials
Authors' conclusion
Patients enrolled in RESHAPE-HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate-to-severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA-FR trials.
Study context
- Population

- Participants
- 506 participants
- Comparison
- MitraClip vs Withholding MitraClip
Methodological detailsinvestigator-initiated, prospective, multicentre, 1:1 randomisation

Further findings
Comparison with COAPT and MITRA-FR populations · baseline
- RESHAPE-HF2 less likely to have MR grade 4+, lower EROA and NT-proBNP, higher eGFR; similar age, comorbidities, CRT therapy and LVEF
