6- Maze Procedure
In the upper chambers of the heart, a doctor uses heat or cold energy or a knife to form a pattern of scar tissue (the maze). The maze interferes with stray heart signals that induce atrial fibrillation because scar tissue does not send electrical signals. If the maze design is made using a scalpel, open-heart surgery is required.
The surgical maze procedure is what it’s called. When another cardiac surgery, such as coronary artery bypass surgery or heart valve repair is required, it is the preferred technique of atrial fibrillation treatment.
