Achieving Optimal Medical Therapy Through Transcatheter Mitral Repair in HFrEF

Official title: Achieving Optimal Medical Therapy Through Percutaneous Treatment of Secondary Mitral Regurgitation to Improve Outcome in Patients With HFrEF

Run by University Medical Center Mainz · NCT07758023 · Data updated 2026-11-12

This trial tests whether early transcatheter edge-to-edge repair (M-TEER) helps patients with HFrEF and secondary MR reach guideline-directed medical therapy faster and more completely, and whether that improves quality of life and outcomes.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with HFrEF (LVEF ≤40%), clinically significant secondary MR (moderate-to-severe or severe), suboptimal GDMT (GDMT score <7), and at least one risk factor suggesting GDMT up-titration may be limited.

Probably not a fit

Patients unlikely to benefit include those with preserved LVEF, non-functional MR, high surgical risk precluding transcatheter repair, or GDMT already maximally optimized.

What this trial studies

ACHILLES-HF is an interventional study evaluating if adding early M-TEER to standard care accelerates up-titration to guideline-directed medical therapy in patients with heart failure with reduced ejection fraction and functional mitral regurgitation. Participants must have suboptimal GDMT and signs that they might not receive full GDMT due to risk factors or symptoms. The study uses M-TEER plus standardized GDMT up-titration and follows patients for changes in therapy, quality of life, and clinical outcomes. The trial is led by Universitätsmedizin Mainz with collaboration from Abbott. Enrollment focuses on patients with HFrEF, significant MR, and likelihood of benefiting from MR reduction to enable GDMT optimization.

Why it matters

Potential benefit: If successful, patients could reach full guideline-directed medical therapy sooner and experience improved symptoms, quality of life, and heart failure outcomes.

How similar studies have gone: Prior work on transcatheter MR repair has shown symptom and functional gains in similar populations, though the specific strategy of pairing with GDMT up-titration is a novel approach.
