卒中和肺静脉消融。引言：射频（RF）消融已成为阵发性房颤（AF）患者的既定治疗方式。射频导管消融的主要局限性是血栓栓塞风险。卒中作为AF触发器消融后的并发症以前没有报道过。方法和结果：五十六例患者接受了AF的局灶源RF消融。四十九例患者（86%）的AF触发器大于或等于1个肺静脉。平均手术时间为227 ± 74分钟。3例（5%）患者发生脑血管事件，均>60岁。三名患者中的两名有短暂性脑缺血发作的既往病史。结论：阵发性房颤患者既往有短暂性脑缺血发作，射频消融术卒中的风险可能更高。
Stroke and PV Ablation. Introduction: Radiofrequency (RF) ablation has become an established treatment modality for patients with paroxysmal atrial fibrillation (AF). A principal limitation of RF catheter ablation is the risk of thromboembolism. Stroke as a complication after ablation of triggers of AF has not been previously reported.Methods and Results: Fifty-six patients underwent RF ablation for a focal source of AF. Forty-nine patients (86%) had AF triggers in greater than or equal to1 pulmonary vein. Mean procedure time was 227 +/- 74 minutes. Cerebrovascular event occurred in 3 (5%) patients, all >60 years old. Two of the three patients had a prior history of transient ischemic attacks.Conclusion: The risk of stroke from RF ablation may be higher in paroxysmal AF patients with prior transient ischemic attack.
