[Abstract]ObjectiveTo study the clinical efficacy and safetyof radiofrequency catheter ablation for atrial fibrillation （AF）by domestic minimally invasive Columbus@ system.MethodsA total of 26 patients with AF who had undergone radiofrequency catheter ablation with Columbus@ system and itssupporting catheter were successively selected.The immediate success rate of surgery，intraoperative related parameters and surgery-related complications were recorded，while the recurrence of AF and the occurrence of adverse events were observed during follow-up.ResultsThe enrolled 26 patients were allparoxysmal AF.Pulmonaryvein isolation was sucessfully achieved during operation，and there were no complications related to radiofrequency catheter ablation during perioperative period. During a mean follow-up of （ 5.92±1.94 ）months，AF recurred in 5 of 26 patients （19.23% ）.No serious adverse events such as embolism，bleeding，atrial esophageal fistula，or death occurred during the follow-up. ConclusionRadiofrequency catheter ablation for AF by using domestic minimall invasive Columbus@ system is clinically feasible， with satisfactory short-term efficacy and safety.

心房颤动（简称房颤）是最常见的持续性心律失常，会增加体循环栓塞和心力衰竭的风险，房颤患者的死亡风险是无房颤患者的 1.5～1.9 倍[1]射频导管消融作为一种安全、有效的房颤治疗方法，药物难治性症状性房颤正是其I类适应证[2]目前，射频消融仍是房颤导管消融的主要能量，临床上使用较广泛的两种心脏电生理三维标测系统分别为美国强生公司生产的Carto系统和Abbott公司研发的Ensite系统，均为美国进口。（剩余5424字）
