Maze Procedure (Surgical)

The maze procedure is indicated for some patients with atrial fibrillation. The procedure is named for the "maze" of new electrical pathways surgeons create for impulses to travel through the heart.
 
If patients are not treatable by medical or percutaneous means, they are referred for the Maze Procedure (Minimally Invasive). This procedure is performed through three small (two-centimeter) incisions on each side of the chest. Using video-assisted technology, the maze lesions are made around the base of the pulmonary veins on the left atrium without opening the patient's chest.
 
Patients referred to the Atrial Arrhythmia Program at UW Hospital and Clinics are assessed by both the cardiac surgical team and the electrophysiology cardiology team, which specializes in the electrical function of the heart.
