As your heart contracts with each heartbeat, blood is squeezed out of the left atrium and into the left ventricle (bottom left of your heart). If you have atrial fibrillation, blood can’t be squeezed out of your left atrium effectively, and can therefore collect in your left atrial appendage and increase your chances of a stroke. Blood thinning medications are a common treatment for atrial fibrillation but they aren’t suitable for everyone. If you can’t take medication, your doctor will recommend surgery to close the opening of your left atrial appendage.
