  • Surgical Treatment of Atrial Fibrillation

    Atrial fibrillation (AF) is the most common cardiac arrhythmia and associated with incremental morbidity and mortality. It is implicated that multiple reentry circuits have been the dominant mechanism of AF. The classical surgical treatment for medically refractory AF is the maze procedure composed of aultiple cuts and sutures within the atrial walls to disrupt the abnormal reentry circuits. Although the maze procedure is recognized as the most effective treatment of AF, it is complicated, time consuming and much invasive. New surgical ablation therapy, applying alternate energy sources (cryothermy, radiofrequency, microwave) have evolved to simplify the maze procedure without cut and suture and demonstrated promising success rates. The optimal lesion set has not yet been defined, Modification of lesion sets and techniques that ensure continuous and transmural lesions may improve the outcomes of ablation therapy and recover rate of sinus rhythm.
