目的评价射频导管消融360例儿童心律失常的疗效和安全性。方法回顾性分析2000年1月~2013年12月360例因心律失常在我院接受射频导管消融的儿童患者360(男213例、女147)例,年龄15个月~14(10±3)岁,平均体质量34 kg。结果急性期消融成功率98.9%(356/360例),4例消融失败。360例患者中,阵发性室上性心动过速308例,占85.6%,307例(99.7%)患者消融成功,其中隐匿性房室旁路伴房室折返性心动过速121例、显性旁路(预激综合征)82例、房室结折返性心动过速105例;室性心律失常42例,其中室性早搏15例(均消融成功),27例室性心动过速(其中4例并发结构性心脏病,25例消融成功);房性心律失常10例(9例消融成功,其中典型心房扑动3例,不典型心房扑动1例,局灶性房性心动过速6例)。所有患儿围术期均未出现明重要并发症。术后随访至少12个月,随访期复发率为2.2%(8/356例),其中6例经再次消融成功。结论射频导管消融术治疗有适应证的心律失常儿童安全有效。
Objective To evaluate the efficacy and safety of radiofrequency catheter ablation in 360 children with arrhythmia. Methods A retrospective analysis of 360 cases (male 213 cases, female 147 cases) of 360 children admitted to our hospital with RF catheter ablation from January 2000 to December 2013 were retrospectively analyzed. The age ranged from 15 months to 14 (10 ± 3) The average body mass is 34 kg. Results The success rate of ablation in acute stage was 98.9% (356/360 cases), and 4 cases failed ablation. Among the 360 patients, 308 cases (85.6%) had paroxysmal supraventricular tachycardia and 307 (99.7%) patients successfully ablated, of which 121 were atrioventricular reentrant tachycardia 82 cases of sexual bypass (Wolff-Parkinson-White syndrome), 105 cases of atrioventricular nodal reentrant tachycardia, 42 cases of ventricular arrhythmia, including 15 cases of ventricular premature beats (all successful ablation), 27 cases of ventricular tachycardia Including 4 cases of structural heart disease, 25 cases of successful ablation); atrial arrhythmia in 10 cases (9 cases of successful ablation, including 3 cases of typical atrial flutter, atypical atrial flutter in 1 case, focal atrial tachycardia Speed 6 cases). All patients had no significant perioperative complications. The patients were followed up for at least 12 months. The recurrence rate at follow-up was 2.2% (8/356 cases), of which 6 cases were successfully ablated again. Conclusion Radiofrequency Catheter Ablation is safe and effective for the treatment of children with arrhythmia indications.
