Heart Valve Disease Clinical Trials

The heart valve clinical trials team is interested in seeing how exciting new heart valves and drugs can help to improve the outcomes and quality of life for those living with the heart valve diseases.

Feel free to call or e-mail the Knight Cardiovascular Institute research team at 503-418-1964 or by emailing . You will then be forwarded to the appropriate research team member who will be able to see if you qualify for any of the clinical trials being offered at OHSU.
