Curing atrial fibrillation (AF) by catheter ablation has significantly improved patient morbidity and mortality. The circumferential pulmonary vein isolation technique is established as the principal procedure, with a high cure rate and acceptable safety, for paroxysmal AF, but new adjunctive ablation strategies targeting the AF substrates and sources for long-standing persistent/chronic AF have been developed. These new techniques include linear ablation, complex fractionated atrial electrogram guided ablation, dominant frequency map-guided ablation, ganglionated plexi ablation and disconnection of the coronary sinus and superior vena cava to ablate the AF substrates and sources. The long-term usefulness of the established technique and these innovative adjunctive approaches for the treatment of AF remains to be investigated.
导管消融治疗心房颤动 (AF) 显著改善了患者的发病率和死亡率。环肺静脉隔离技术已确立为阵发性 AF 的主要治疗方法，具有较高的治愈率和可接受的安全性，但针对持续性/慢性 AF 的 AF 基质和源的新辅助消融策略已经发展起来。这些新技术包括线性消融、复杂碎裂心房电图指导的消融、主导频率图指导的消融、神经节丛消融以及冠状窦和上腔静脉的分离以消融 AF 基质和源。现有的技术和这些创新的辅助方法治疗 AF 的长期效果仍有待研究。
