The surgery to correct atrial fibrillation is called the maze procedure. This is always an option for people who suffer from a severe cause. Medicines and ablation are always considered first before an invasive surgery. You may be a candidate for this type of surgery if you are already going to have heart surgery. If this is the situation the maze procedure is likely to happen at the same time. The maze procedure consists of getting rid of tissue to create new scar tissue which will in turn block the extra electrical impulses that are coming from the heart. This requires that it is an open heart surgery. There are less invasive surgical methods that are being developed.
