Corvia Clinical Program
Corvia Medical, in collaboration with its clinical investigators and advisors, is committed to generating and sharing unbiased evidence to support atrial shunting therapy for heart failure. Multiple studies have been conducted around the world to evaluate the Corvia Atrial Shunt System for the treatment of HF patients with left atrial pressure who remain symptomatic despite standard Guideline Directed Medical Therapy (GDMT). Several studies, including the recently initiated RESPONDER-HF study, are ongoing.
Studies include the following:
