Maze Procedure—Open Surgery
Maze is a surgical procedure for the heart. A maze-like pattern of incisions is made in the upper chambers of the heart. The chambers are called the atria.

Maze is done to treat atrial fibrillation. Fibrillation is abnormal beating of the heart muscle. It is caused by erratic electrical impulses that travel through the heart muscle. These impulses can cause the chambers to beat too fast. This can decrease blood flow through the heart. Atrial fibrillation can also cause blood clots to form in the heart that can travel to the brain and cause a stroke.
Maze is used to treat severe cases that did not respond to medications or other procedures. Electrical impulses cannot flow through scar tissue. By creating specific patterns of scar tissue, maze surgery creates a pathway for healthy impulses and blocks erratic impulses.
