冷盐水灌注冠状静脉窦内旁道射频消融治疗

目的探讨冷盐水灌注射频消融冠状静脉窦内及其分支旁道的方法学及有效性、安全性。方法选择11例经心内膜途径标测和消融失败者,经冠状静脉窦内或其分支内标测到旁道电位或A-V（V-A）最近、融合处,应用普通温控或冷盐水灌注温控电极,在冠状静脉窦或其分支内射频消融。结果11例患者均消融成功。结论冠状静脉窦内及其分支的心外膜旁道射频消融治疗安全、有效。

Radiofrequency Catheter Ablation with Cold Saline Infusion in the Acceddsoty Pathway of Coronary Sinus

Objective To discuss the Methods,efficacy and safety of radiofrequency catheter ablation with cold saline infusion in coronary sinus and its accessory pathway.Method 11 patients were selected which were failed in mapping and ablation by endocardium,radiofrequency catheter ablation is operated in coronary sinus and its accessory pathway by using common or cold saline water filled warm control elcctrode for each sample after which shunt electric potential was mapped in coronary sinus or its accessory pathway, the place nearest to A V（V-A）, A V（V-A） recency,confluence.Results 11 patients had successful ablation. Conclusion Radiofrequency catheter ablation operated in coronary sinus and accessory pathway,is safe and efficacy.
