Authors' conclusion

In symptomatic moderate-to-severe FMR, TEER plus GDMT significantly reduces death or hospitalisation due to heart failure and hospitalisation due to heart failure at 24 months.

Study context

Population
Patients with symptomatic moderate-to-severe functional mitral regurgitation (FMR)Three randomised trials (MITRA-FR, COAPT, and RESHAPE-HF2)
Participants
1,422 patients
Comparison
Transcatheter edge-to-edge repair (TEER) plus guideline-directed medical therapy (GDMT) with GDMT alone in FMR
  • TEER plus GDMTn = 703
  • GDMT alonen = 719reference
Outcome
Death or first hospitalisation due to heart failure
Follow-up
24 months

Not significantly different between treatment groups but became significant after excluding MITRA-FR in the leave-one-out analysis
