So you'll still need to take an anticoagulant if your risk of stroke remains high. Studies haven't proved that ablation for atrial fibrillation lowers your risk of stroke. But that is only true if your risk of stroke is low. Many people think that having ablation means they'll be able to stop taking an anticoagulant (also called a blood thinner) every day to prevent stroke.

The doctor inserts thin, flexible tubes called catheters into a vein, usually in the groin or neck.You'll get medicines to make you sleep or feel sleepy and comfortable during the procedure. It's like working on the spark plugs in your car without having to open the hood. Your doctor can get into your heart-without surgery-and fix the misfiring.
