经导管射频消融治疗老年阵发性心房颤动临床分析

Catheter ablation for paroxysmal atrial fibrillation in elderly patients

摘要:

目的 评价射频消融治疗老年阵发性房颤患者的有效性和安全性。方法 连续入选接受首次房颤射频消融术治疗的药物难治性阵发性房颤患者85例, 按年龄大小分为老年人房颤组（≥60岁, 45例）和非老年人房颤组（＜60岁, 40例）, 所有患者接受环肺静脉隔离术治疗。观察患者房颤的复发情况。结果 通过（37.2±3.2）月的随访, 85例患者中, 共23例（27.1%）出现房颤复发, 其中≥60岁与＜60岁年龄组在复发率上无显著性差异（12/45 vs 11/40, P=0.931）。85例患者中无1例出现消融相关严重并发症。结论 经导管射频消融是治疗老年阵发性房颤的有效手段, 其有效性及安全性与非老年人群并无临床差异。

Abstract:

Objective To evaluate the efficacy and safety of catheter ablation for paroxysmal atrial fibrillation(AF) in elderly patients. Methods A cohort of 85 consecutive patients undergoing initial ablation procedure for drug-refractory AF was included in this study. Patients were divided into elderly group (≥60 years, 45 cases) and non-elderly group (＜60 years, 40 cases). All patients received circumferential pulmonary vein isolation procedure successfully. Recurrence of AF was observed. Results During (37.2±3.2) months follow-up, 23 cases(27.1%) had AF recurrence. No significant difference was found between elderly and non-elderly groups (12/45 vs 11/40, P = 0.931). No patient developed severe ablation-related complication. Conclusion Catheter ablation is an effective and safe treatment for paroxysmal AF in non-elderly patients, as well as in elderly patients.
