目的探讨射频消融术治疗阵发性室上性心动过速失败的原因。方法回顾性分析1026例采用射频消融术治疗阵发性室上性心动过速患者的治疗结果。结果 1026例患者中,991例首次射频消融治疗成功,成功率96.6%。失败35例,其中左侧旁道13例,右侧旁道13例,房室结双径路9例,19例再次行消融治疗获得成功,总成功率98.4%(1010/1026)。结论初学者消融失败原因主要为导管操作不熟练和诊断不够明确,熟练者主要因解剖结构异常导致导管操作困难和靶点图识别不准确。
Objective To investigate the causes of failure of radiofrequency ablation for the treatment of paroxysmal supraventricular tachycardia. Methods A retrospective analysis of 1026 patients treated with radiofrequency ablation in patients with paroxysmal supraventricular tachycardia treatment results. Results Among the 1026 patients, 991 cases achieved the first successful radiofrequency ablation with a success rate of 96.6%. Thirty-five patients failed, including 13 cases of the left bypass and 13 cases of the right bypass, and 9 cases of the dual ventricular atrioventricular node. The success rate was 98.4% (1010/1026). Conclusions The main reason for the failure of beginner ablation is the unskilled catheterization and the diagnosis is not clear enough. The skilled person mainly has difficulty in catheter operation and inaccurate target image recognition due to abnormal anatomy.
