射频消融术治疗小儿阵发性室上性心动过速中的效果观察

Efficacy observation of the radiofrequency catheter ablation treating on paroxysmal supraventricular tachycardia in children

目的 评估经导管射频消融术（RFCA）治疗小儿阵发性室上性心动过速（PVST）的临床效果.方法 回顾性分析2009年1月～2013年1月四川省人民医院收治的97例PSVT患儿.其中男65例,女32例,手术时平均年龄（7.1±1.8）岁,平均体重（32.4±8.9）kg.射频消融术后平均随访（27±21）个月.分析RFCA术的治疗情况.结果 本研究纳入的97例患儿中,房室折返性心动过速（AVRT）患儿66例（68.0％）,其中左侧旁道38例（57.6％）,右侧旁道28例（42.4％）;房室结折返性心动过速（AVNRT）患儿31例（32.0％）.射频消融即刻成功95例（97.9％）,其中6例在随访过程中复发（6.2％）.复发患儿给予再次射RFCA治疗,随访半年,未见复发,术后随访所有患儿无消融手术相关并发症的发生.结论 RFCA可安全有效治疗小儿PSVT.

Objective To observe the efficacy of radiofrequency catheter ablation （RFCA） in pediatric patients with paroxysmal supravetricular tachycardia （PSVT）.Methods The clinical data of 97 pediatric patients with PSVT,who underwent RFCA in Sichuan Provincial People＇s Hospital from January 2009 to January 2013,were retrospectively analyzed.65 male and 32 female were found in 97 pediatric patients; the average of age and weight were （7.1±1.8） years and （32.4±8.9） kg respectively; and they were followed up for （27±21） months.RFCA surgery treatmen was analyzed.Results In this cohort,66 cases （68.0%） were diagnosed with atrio-ventricular reentrant tachycardia（AVRT）,which included 38 cases （57.6%） with left ventricular outflow and 28 cases （42.4%） with right ventricular outflow; and 31 cases （32.0%） with atrio-ventricular nodal reentrant tachycardia （AVNRT）.The success of the RFCA was achieved in 95 patients （97.9%）; while recurrence occurred in 6 patients （6.2%）.However,after second ablation,all those 6 patients were not recurrence.In this cohort,no complication was found during follow-up.Conclusion RFCA is safely and effectively in treating pediatric patients with PSVT.
