Kodex-EPD系统指导下冷冻球囊消融治疗持续性心房颤动的初步观察

The preliminary observation of cryoablation therapy for persistent atrial fibrillation under the guidance of the Kodex-EPD system

目的 探讨Kodex-EPD三维标测系统的指导下,进行冷冻球囊消融治疗持续性心房颤动(简称房颤)的有效性与安全性。方法 连续入选2022年1~6月在阜外医院深圳医院心律失常中心Kodex-EPD系统指导下行冷冻球囊消融持续性房颤患者25例,术后随访12个月观察有无房性心律失常复发。结果 术中所有患者肺静脉隔离率100%,23例行肺静脉隔离+左房顶部线消融,肺静脉口部、左房顶部均形成完整的低电压区。手术严重并发症和血管并发症均未发生。术后12个月随访结束时,19例(76%)患者维持窦性心律,6例(24%)房颤复发。结论 Kodex-EPD系统指导下冷冻球囊消融治疗持续性房颤是一种有效而且安全的策略。

Objective To investigate the efficacy and safety of cryoballoon ablation in patients with persistent atrial fibrillation(AF)under the guidance of the Kodex-EPD three-dimensional mapping system.Methods From Janu-ary to June 2022,25 patients with persistent AF underwent cryoballoon ablation using the Kodex-EPD system at the Arrhythmia Center of Shenzhen Hospital,Fuwai Hospital.The patients were followed up for 12 months to monitor the recurrence of atrial arrhythmia.Results The pulmonary vein isolation rate for all patients was 1oo%.Among them,23 patients underwent pulmonary vein isolation in addition to left atrium top line ablation,resulting in the formation of a complete low voltage area at the pulmonary vein ostium and left atrium top.No severe surgical com-plications or vascular complications were recorded.At the end of the 12-month follow-up,19 patients(76%)main-tained sinus rhythm,while AF recurred in 6 patients(24%).Conclusion Cryoballoon ablation guided by the Ko-dex-EPD system for persistent AF demonstrates itself as an effective and safe strategy.
