Mini-Maze Procedure—Minimally Invasive Surgery
Maze is a surgical procedure of the heart. A maze-like pattern of scars is made in the upper chambers of the heart. The chambers are called the atria.
A traditional maze surgery requires the chest to be opened and the heart to be stopped. A mini-maze is done with small incisions and special surgical tools. This often leads to shorter recovery time and lower risk of infection.

Maze is done to cure atrial fibrillation. Fibrillation is abnormal beating of 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 astroke.
Maze is used to treat severe cases that did not respond to medicine 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.
