摘要
In the past decade, there is a great progress in the treatment of atrialfibrillation (AF) by transcatheter ablation. The catheter-based procedures have developed fromMaze-like linear lesion, focal lesion to segmental electrical isolation of pulmonary veins andcircumferential ablation under guidance of anatomical mapping, ablation energy developed fromradiofrequency to multiple energy such as radiofrequency, ultrasound and cryoablation; and successrate has risen to 90% from around 30% in the past. Catheter ablation has been widely accepted as atreatment of AF and tends to substitute pharmacological therapy and become first-line treatmentgradually. It must point out that, however, catheter ablation of AF is not perfect and there aremany issues desiderating resolution.
