Atrial fibrillation is the most common arrhythmia and is known to be in connection with stroke, dementia, heart failure and increased risk of death. For drug-refractory atrial fibrillation, surgical or catheter ablation is recommended. Early attempts to design procedures to ablate atrial fibrillation and restore sinus rhythm culminated in the Cox-Maze Ⅲ procedure, which was the first truly successful procedure. However, Cox-Maze Ⅲ procedure is complex and technically demanding, so it has been extensively modified with new techniques to create new types of surgical ablation procedures: Cox-Maze Ⅳ procedure, minimally invasive Cox-Maze Ⅳ procedure, and the latest “hybrid approach”. This review mainly discusses these surgical treatment strategies and the latest research progress.
