心房颤动(房颤)是常见的心律失常,随着年龄的增长,房颤的发生率也随之增加,目前射频消融术已成为房颤的一线治疗方案.射频消融术在围术期存在着栓塞事件、大出血事件、小出血事件等并发症,如何选择安全有效的抗凝方案对于减少围术期并发症的发生尤为重要.传统的抗凝方案为肝素桥接法,而不中断华法林法、口服新型抗凝药等新型抗凝方案的安全性及有效性也逐渐被证实并广泛采用.%Atrial fibrillation is a common arrthymia,and the incidence of atrial fibrillation increases with age grows. Catheter ablation is recommended as a first-line treatment for patients with atrial fibrillation.On account of the periproce-dural complications such as embolic events,major bleeding and minor bleeding events,selecting the right anticoagulation method for patients undergoing atrial fibrillation ablation is particularly important to minimize complications.The traditional anticoagulation strategy is heparin bridging.There is growing evidence showing that uninterrupted warfarin and new oral anti -coagulants are safe and effective.
