Abstract :

Atrial fibrillation (AF) is the most common arrhythmia worldwide. Stroke is the main cause death in patients with AF. The maze procedure is the gold standard for surgical treatment of AF. Current guidelines for AF by the Society of Thoracic Surgeons are especially focused on the maze procedure during concomitant cardiac surgery as well as the primary procedure after failed catheter and medical therapy for AF. Current trends indicate that only 38% of patients having concomitant AF during cardiac surgery undergo maze procedure. Given this fact, we sought to show that maze procedure is a safe, effective surgical procedure in eliminating AF. Mortality and morbidity rates after maze are not different when comparing with cardiac surgery alone. Early and late survival improves after maze. Restoring normal sinus rhythm is much better when maze procedure is added. Rates for early and late stroke go down after maze, likely strongly related to the left atrial appendage removal during maze procedure. Surgical times are clearly shorter when using alternative energy sources as bipolar radiofrequency and/or cryothermia in order to perform the maze procedure. In conclusion, to sum up, there is no reason to avoid the maze procedure when indicated. Because of the high effective rate of sinus conversion as well as its low rate of complications, maze procedure should be performed when indicated during the course of cardiac procedures, even as a primary procedure for cases of standalone AF after failed catheter-based or antiarrhythmic therapies
