Maze Procedure with the AtriCure Radiofrequency System

This video interview is with a 75-year-old patient, on postoperative day #3, after a surgical aortic valve replacement surgery for critical aortic stenosis, combined with a radiofrequency maze procedure for atrial fibrillation.

His aortic valve was replaced with a 25mm Edwards Inspiris Resilia bovine bioprothetic valve. The maze procedure was performed with the AtriCure radiofrequency system, along with placement of a 50mm AtriCure left atrial clip occluder.

The maze procedure treats atrial fibrillation by creating a specific pattern (maze) of scar tissue, redirecting the reentrant electrical currents that cause atrial fibrillation. Clip occlusion of the left atrial appendage reduces the risk of embolic stroke from afib. The success rate for a maze procedure is 80 to 90%, and is well-tolerated.

The patient is being discharged on postoperative day #3, with minimal to no discomfort and in normal sinus rhythm. Surgical aortic valve replacement, combined with a maze procedure, can be performed through a conventional median sterneromy with minimal pain, short lengths of stays, and early recovery.
