Could a birth-tissue patch protect heart surgery patients from dangerous flutters?

This early-stage study tested whether placing a human amniotic membrane (hAM) on the heart during bypass surgery could safely lower inflammation and reduce the chance of developing atrial fibrillation afterward. Twenty-seven adults having their first bypass surgery were randomly assigned to receive either the membrane or standard care. The main goals were to check for side effects and compare rates of post-operative atrial fibrillation between the two groups.
