In some cases, your doctor can treat the abnormal heart cells that are causing atrial fibrillation through cath lab and surgical procedures.
In an ablation, a catheter (small, flexible tube) is threaded through a blood vessel to your heart. A device on the catheter is used to make a tiny scar so the abnormal cells can't send faulty signals.
A maze procedure creates scar tissue to keep abnormal electrical impulses from traveling through your heart. This procedure is done in open-heart surgery.
