REDUCE LAP-HF II Trial
LANDMARK TRIAL in HFpEF
REDUCE LAP-HF II is the largest device therapy trial for heart failure patients with preserved ejection fraction (HFpEF), the biggest unmet need in cardiology. This global, landmark, phase III, sham-controlled trial is evaluating the Corvia Atrial Shunt in heart failure patients to reduce HF-related hospitalizations and improve quality of life through a reduction in left atrial pressure (LAP), the primary cause of HF symptoms. Patients will be followed out to 5 years post implant, and 12-month follow-up is not complete.
The 12-month primary endpoint analyses reinforce the safety and efficacy of the device observed in previous studies and have newly defined treatable patient population for atrial shunt therapy.
Responder Group Highlights
50% of the study population benefited significantly from atrial shunt therapy despite an overall neutral trial2,3
Neutral primary outcome when including all patients (win ratio=1)
RESPONDER GROUP (n=313)
Positive outcome in patients with normal exercise PVR (<1.74 WU)4 and no cardiac rhythm device (win ratio5=1.5, p=0.004)

- Upper tertile, which roughly corresponds to peak exercise in a healthy adult >55 years (≤1.8WU).
- In win ratio calculation, all patients are compared with each other in pairwise manner on values of the components in a hierarchical manner (1 = neutral, >1 treatment better, <1 sham better).
