Study Design of the EDGEFIRM Trial: TEER Versus GDMT in Atrial Functional Mitral Regurgitation and HFpEF.

New randomized trial will test catheter-based heart repair for a specific heart failure type lacking prior intervention evidence.

The EDGEFIRM trial protocol describes a randomized controlled trial comparing transcatheter edge-to-edge repair (TEER/MitraClip) versus guideline-directed medical therapy in patients with atrial functional mitral regurgitation and HFpEF, a specific HF subtype with limited interventional evidence. Announcement of this trial design is relevant for tracking emerging cardiovascular intervention evidence.

Why it surfaced

HFpEF with atrial functional MR is a large under-addressed clinical population. First dedicated RCT (EDGEFIRM) comparing TEER vs medical therapy represents a significant trial design to track.
