Heart fix may heal your gut, new study hints

This study looks at how a common heart valve procedure called TAVI changes the gut microbiome in older adults with aortic stenosis. Researchers will collect blood and stool samples before and three months after TAVI to measure bacterial byproducts and diversity. The goal is to see if improving heart function can restore a healthier gut environment, which might reduce inflammation and complications. 40 participants are enrolled at a Swiss hospital.
