Authors' conclusion

Mitral valve interventions in elderly patients are increasing over time, driven by transcatheter therapies. Five-year mortality varied by type of intervention and was significantly influenced by frailty and social vulnerability.

Study context

Population
Medicare fee-for-service patients ≥65 years hospitalized for surgical or transcatheter mitral valve intervention, 2017–2022
Participants
172,478 mitral valve interventions
Exposure
Surgery vs transcatheter mitral valve replacement (TMVR) vs M-TEER
Outcome
Mortality
Follow-up
5 years
