Magnetic Fluid Injected Into The Heart May Prevent Strokes, Scientists Think
Published on March 23, 2026.
Scientists have found a new technique that could potentially prevent stroke in people with atrial fibrillation, a heart rhythm disorder that causes the heart's upper chambers or atria to beat chaotically. The method involves injecting a magnetically guided liquid into the heart, which then hardens to permanently seal the pouch from the inside. Early tests in rats and pigs suggest this method could potentially lower the risk of stroke in patients with this condition. The technology has only been tested in animals, but it remains in the experimental stage of its development. Despite the promising results, there are still practical problems to resolve before it can be used in patients.
