Authors' conclusion

TMVR using dedicated TF devices demonstrates favorable safety, durable MR reduction, and sustained functional improvement in high-risk patients.

Study context

Population
Patients with mitral regurgitation (MR) undergoing transfemoral (TF) transcatheter mitral valve replacement (TMVR) with dedicated devices (CHOICE-MI Registry)9 different devices
Participants
124 patients
Outcome
All-cause mortality or HF hospitalization
Follow-up
Up to 2 years

Main finding

As reported in the abstract

Primary endpoint rate at 2 years

52.4% (95% CI: 40.2%-62.1%)

Observational data: associations, not effects.

Further findings

Technical success

Technical success
113 of 124 patients (91.1%)

Residual MR ≤1+ · discharge
