Despite new surgical ablation guidelines from The Society of Thoracic Surgeons and The Heart Rhythm Society, atrial fibrillation remains largely untreated. According to Dr. Marc Gillinov, the Chairman of the Department of Cardiothoracic surgery at the Cleveland Clinic, AFib is treated in only 50% of cases when patients undergoing heart surgery have concomitant AFib. “This is a mistake,” states Dr. Gillinov, “This is a once in a life-time opportuntiy to do a Maze procedure and free the patient from the long-term risks of AFib.”

Watch this video to learn more about Dr. Gillinov’s views and recommendations for using the Maze Procedure during a concomitant CABG, valve and aneurysm operation.

During the Maze procedure, radiofrequency and cryoablation systems are
used to heat and freeze heart tissue to create scars  in a specific
pattern to block abnormal electrical conduction.

Lesion Set Options


To treat Atrial Fibrillation using ablative technologies, there are
four lesion sets that surgeons typically use.

  See All Lesion Sets.

The Pulmonary Vein Isolation (PVI) and Left Atrial Appendage Management (LAAM)
lesion set is shown above and has about a 60% AFib Free (nPAF).  There are four
lesion sets that are used today each with varying degrees of success.

Complications of the
Maze Procedure

Complications of the Maze Procedure


During the Ablate AF Trial, 84% of patients were free of AFib symptoms at 6 months1.  Complications are reported to be less than 1% for surgical ablation2. Complications may include bleeding, infection, blood clots, kidney failure, and cardiac arrhythmia3.

Maze Procedure Heart Surgical 33257 Class 1 The Maze procedure ablates the heart using radiofrequency or cryo energy to restore the heart to normal sinus rhythm
Atrial Fibrillation ABLATE AF AtriCure, Inc. NCT01694563 http://schema.org/Cardiovascular ApprovedThe primary objective of this post-approval study is to evaluate the clinical outcomes in a cohort of patients with non-paroxysmal forms of atrial fibrillation (persistent or long-standing persistent) treated during commercial use of the AtriCure Synergy Ablation System by physicians performed the Maze IV procedure.
