Transcatheter edge-to-edge repair plus guideline-directed medical therapy versus guideline-directed medical therapy alone for symptomatic functional mitral regurgitation: a comprehensive, up-to-date meta-analysis of randomised trials

Transcatheter edge-to-edge repair (TEER) is among the treatments for functional mitral regurgitation (FMR), but its benefits over guideline-directed medical therapy (GDMT) alone are discordant. We conducted a meta-analysis of randomised trials comparing long-term outcomes between these treatment strategies.

We aimed to compare long-term clinical outcomes between TEER plus GDMT and GDMT alone in symptomatic moderate-to-severe FMR.
