Residual Mitral Regurgitation as a Long-Term Predictor of Mortality After Mitral TEER
- Registry study (5-year follow-up of the MITRA-PRO registry)
Authors' conclusion
Residual MR assessed by intraprocedural MitraScore after M-TEER independently predicts 5-year mortality.
Study context
- Population
- Patients after mitral transcatheter edge-to-edge repair (M-TEER)
- Participants
- 1,491 patients
- Exposure
- Mild or less residual mitral regurgitation (MR) vs relevant residual MR after M-TEER
- Outcome
- Mortality
- Follow-up
- 5 years
Main finding
As reported in the abstract
5-year mortality
Observational data: associations, not effects.
Further findings
5-year mortality, degenerative MR (subgroup)
5-year mortality, functional MR (subgroup)
Intraprocedural MitraScore and mortality
- Relationship almost linear
Time-dependent predictors of mortality
- Early risk driven by advanced disease and procedural factors; residual MR prognostic after 30 days and associated with excess long-term mortality
