Atrial fibrillation is a common heart condition characterized by a rapid, irregular heartbeat stemming from the heart's upper chamber. It is a leading cause of stroke from clots that form in a small pouch of the heart called the left atrial appendage (LAA). While several treatment options exist, they have many drawbacks, and risks often remain. But now, researchers have developed a promising new treatment involving magnetic fluids. Their study, published in Nature, describes the new procedure and results from rat and pig studies.
