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