LAA closure

LAA closure is a medical procedure that seals off the left atrial appendage (LAA), a small pouch in the heart where blood clots can sometimes form in people with atrial fibrillation. These clots can travel to the brain and cause a stroke. By closing the LAA, doctors aim to reduce stroke risk without relying solely on blood-thinning medications. This can be done with a device that is inserted through a catheter into the heart, which then seals off the LAA, helping to prevent blood clots from forming and traveling to the brain.
