Heart valve bacteria under the microscope: could they cause Post-Surgery problems?
NCT ID NCT07075601
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study examines bacteria living on heart valves in 200 patients having aortic valve surgery. Researchers want to see if these bacteria are linked to serious complications after surgery, like stroke or infection. The goal is to better understand how oral health and heart disease may be connected.
