Pneumonia Heart attack or stroke New heart rhythm problems What complications can happen after open-heart maze procedure for atrial fibrillation (AFib)? Maze procedure. AF is the most common irregular heart rhythm in the United States, and it originates in the atria, or the heart's upper chambers. Thoracoscopic Maze Procedure. In this procedure, called the Cox-Maze IV, many of the lesions of the conventional version are replaced with linear lines of ablation using bipolar RF energy. Clinical Cardiac Electrophysiology. The Maze procedure, also sometimes called the Cox-Maze procedure, is a surgical treatment for atrial fibrillation (AF). Maze procedure: The maze procedure is surgery for atrial fibrillation using small incisions, cryotherapy, radiofrequency ablation, microwaves, or ultrasound to create scar tissue across the left and right atriums; the normal flow of electrical impulses is blocked and forced to travel in a precise pattern (like a maze) through the heart to the ventricles. "Maze" refers to the series of incisions arranged in a maze-like pattern in the atria.Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures, are used.. History.

Surgeons are looking at newer techniques to … Or, the doctor uses a scalpel to make several precise incisions. Aortic valve replacement/repair (AVR) and coronary artery bypass surgery (CABG) are two of the most common surgeries performed. Our experience with the Cox-Maze IV procedure reported comparable success rates to the Cox-Maze III procedure (traditional surgical procedure) with freedom from AF at last follow-up of greater than 90 percent. Complications of the Maze Procedure. Complications are reported to be less than 1% for surgical ablation 2. Maze is a surgical procedure used to treat atrial fibrillation. It is as effective as the standard Cox Maze surgery. This method is more complex and takes longer. With AF, a risk factor for stroke, the electrical signal that normally causes the heart’s atria to contract in an orderly fashion However, patients who have AF and are undergoing these surgical procedures are less likely to have a SA procedure performed (11,12).Therefore, we investigated whether operative risk was increased when adding the Cox Maze III/IV procedure to AVR or CABG surgery (). The MACE procedure is a surgical procedure designed to help patients with neurogenic bowel (chronic constipation and/or inability to control stool elimination due to a neurologic problem) attain fecal continence. Convergent procedure: This pairs catheter ablation with a mini maze. ... Atrial Fibrillation Surgery … Complications from surgical ablation maze procedures have generally been less than 1%. A doctor creates a pattern of scar tissue (the maze) in the upper chambers of the heart by applying heat or cold. The Maze procedure is major surgery and patients may experience any of the normal complications associated with major surgery and anesthesia, such as the risk of bleeding, pneumonia, or infection.
