激动标测和起搏标测联合指引下解剖消融治疗特发性右室流出道室性早搏的效果

Clinical Value of Anatomical Ablation Treatment for Idiopathic Right Ventricular Outflow Tract Premature Beats Under the Guidance of Combined Excitation Mapping and Pacing Mapping

目的探讨激动标测和起搏标测联合指引下解剖消融治疗特发性右室流出道(RVOT)室性早搏的临床价值。方法回顾性分析2023年1—10月在郑州大学第一附属医院心血管内科和许昌市中心医院心血管内科住院接受室性早搏射频消融术的36例患者的资料,经电生理检查证实室性早搏来源于RVOT,根据术中室性早搏数量多少灵活采用激动标测和或起搏标测找到靶点进行对应肺动脉根部瓣下和瓣上联合消融,分析该方法即刻及3个月成功率。结果术中室性早搏数量少的患者也可以快速有效地进行导管消融术并取得满意的远期效果。结论激动标测和起搏标测联合指引下解剖消融治疗特发性RVOT室性早搏临床可行,效果较好。

Objective To investigate the clinical value of anatomical ablation treatment for idiopathic right ventricular outflow tract(RVOT)premature beats under the guidance of combined excitation mapping and pacing mapping.Methods A retrospective analysis was conducted on 36 patients admitted to the Cardiovascular Department of the First Affiliated Hospital of Zhengzhou University and the Cardiovascular Department of Xuchang Central Hospital from January to October 2023,who were confirmed by electrophysiological examinations to have idiopathic premature ventricular contractions of RVOT.Based on the number of premature ventricular contractions during procedure,flexible use of excitation mapping and/or pacing mapping to locate the target point for pulmonary artery root subvalvular and supravalvular combined ablation.The immediate and 3-month success rates of this method were analyzed.Results Patients with a small number of premature ventricular contractions during procedure can also undergo catheter ablation quickly and effectively,achieving satisfactory long-term results.Conclusion Anatomical ablation therapy for idiopathic RVOT premature contractions under the guidance of combined excitation mapping and pacing mapping is clinically feasible and effective.
