Heart surgery may reshape your gut microbiome
NCT ID NCT07052071
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether replacing a narrowed heart valve (TAVI) changes the types of bacteria living in the gut. Researchers will collect stool and blood samples from 40 patients before and after the procedure. The goal is to see if improved blood flow from the new valve helps restore a healthier gut microbiome, which could open new doors for heart disease treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Transcatheter Aortic Valve Implantation (TAVI) procedure
What this could lead to
If successful, this could reveal a connection between heart function and gut health, pointing toward new ways to treat cardiovascular disease by targeting the microbiome.
What could go wrong
This is a small, early observational study with only 40 participants. It looks at changes in gut bacteria, not direct treatment outcomes, so results may not lead to immediate medical advances.
