Rhythm control therapy is used in atrial fibrillation (AF) management to improve AF-related symptoms along with rate control. AF catheter ablation is effective in maintaining sinus rhythm and has an acceptable complication rate. Compared with antiarrhythmic drugs, AF catheter ablation is superior with respect to arrhythmia-free survival and improvement in the quality of life. Therefore, AF ablation is recommended for rhythm control after the failure of antiarrhythmic drugs and is sometimes considered a first-line therapy for AF patients. Radiofrequency and cryoballoon ablation show similar efficacy, with slightly different complication profiles. Surgery for AF is also an effective rhythm control therapy and should be considered in patients undergoing cardiac surgery or in those with failed catheter ablation. For patients undergoing AF catheter ablation, performing ablation under uninterrupted warfarin or non-vitamin K oral anticoagulant treatment is recommended for periprocedural stroke risk management. Here, we review existing data and discuss the general principles of AF catheter and surgical ablation in patients with AF.
