The Maze Procedure

A surgical treatment for AF—the Maze procedure—was developed about 10 years ago. Developed primarily for patients without valve disease, it has been increasingly applied during valve surgery for patients with AF and valve disease. The procedure short-circuits the chaotic signals that cause AF, allowing the sinus node to reassert its direction of electrical signaling. Restoration of normal rhythm can preclude the need for drug therapy.

As it is usually performed today, a radio frequency probe (a device that emits sound waves at a frequency that can injure or destroy small and very highly selected tissue regions) or a cryoprobe (a device that freezes and thus injures or destroys similarly limited areas of tissue), is used to injure a ring of tissue around each of the four pulmonary veins, around the left atrial appendage, around the mitral valve annulus, along the route of the coronary sinus (which carries blood back to the heart from the cardiac veins), and along a line connecting the pulmonary veins and the mitral valve annulus. This effectively isolates the areas from which the chaotic electrical signals usually arise
