The Modified-Maze procedure is used to reroute errant electrical signals in the heart that disrupt normal heart rhythm. Specific areas within the atria ­­– the heart's two upper chambers – where the heart’s electrical impulses become disorganized are pinpointed and destroyed by radio waves, cryothermy (extreme cold), laser, ultrasound waves or microwaves. Once these areas heal, the scar tissue forms lesions that electrical impulses cannot travel through. As a result, the charges are deflected into the intended pathways. The Modified-Maze procedure requires that the chest be opened, so it usually only performed when medical management has proven ineffective or when another open-heart procedure is being performed.
