Key result
M-TEER shows conflicting clinical benefit across randomized trials in functional mitral regurgitation with heart failure.
Urges caution with M-TEER in functional MR and HF; leaves open refined patient selection for future trials.
For patients with functional mitral regurgitation (FMR) and symptomatic heart failure (HF), randomized trials of mitral transcatheter edge-to-edge repair (M-TEER) have produced conflicting results.
