The Maze procedure is a highly effective treatment for atrial
fibrillation that can be done both surgically and through a modified
approach. The goal of the Maze procedure is to interrupt the electrical
impulses that are responsible for the chaotic rhythm of atrial
fibrillation and create a new pathway, or maze, through which electrical
impulses travel. This restores normal heart rhythm and prevents
During the open procedure, Lankenau’s cardiac surgeons make incisions in
both the right and left atria of the heart. When the incision heals,
scar tissue forms and prevents electrical impulses from passing through
the heart. During the modified approach, a catheter is inserted through
a small incision outside the heart. Instead of making surgical
incisions, a radiofrequency device or cryo technology is used to create
the lesions on the atria. Lankenau offers the Maze procedure on its own
or as part of a “hybrid” procedure where valve surgery or coronary
artery bypass surgery are performed at the same time.
