A Foundation of Clinical Evidence

The Corvia Atrial Shunt is the most clinically studied atrial shunt for the reduction of Left Atrial Pressure (LAP) in HFpEF/HFmrEF patients. Over 750 patients have been studied to date and multiple studies are ongoing.

REDUCE LAP-HF Clinical Program

Corvia Medical is committed to generating unbiased evidence to support atrial shunting for heart failure in collaboration with its clinical investigators and advisors.

Through multiple REDUCE LAP-HF studies around the world, clinical results have consistently established the efficacy and safety of the Corvia Atrial Shunt System in heart failure patients with an EF≥40% and elevated left atrial pressure.

PWCP REDUCTION

Immediate and significant PCWP reduction of 3-5mmHG with clinical improvement sustained over 12 months.2

QUALITY OF LIFE

33% improvement in MLWHF score
sustained through the 3-year mark.3,4

HF HOSPITALIZATIONS

69% of implanted patients were free from any HF hospitalization and 91% were free from >1 HF hospitalization through the 3-year mark.4

SURVIVAL

87% survival at 3 years for implanted patients.3,5-7

SAFETY

The Corvia Atrial Shunt demonstrated consistent, durable results in nearly 100 patients across 3 studies.
