预激综合征合并三尖瓣下移畸形的射频消蚀（附八例报告）

Radiofrequency catheter ablation for accessory pathways associated with congential heart diseases of Ebstein's anomaly

对８例先天性三尖瓣下移畸形合并右侧房室旁路的患者行射频消蚀，结果显示：尽管该类患者有心脏结构的异常，但消蚀导管的选择、操作方法及过程无特殊之处，总操作时间、ｘ线投照时间以及放电次数也与心脏结构正常的右侧房室旁路相似，成功率高。这一结果证实，射频消蚀为合并先天性心脏病的预激旁路的治疗提供了新的途径。

Abstract Radiofrequency catheter ablation (RFCA) for accessory pathways (APs)has been successfully attempted in 8 patients with congential heart diseases of Ebstein's anomaly , including male 8 cases,age range from 5 to 33 years, history of tachycardia from 1 to 5 years and 2 cases with paroxysmal atrial fibrillation.The results were that the 8 patients have 3 APs in right-sided from posterior to lateral wall location, total procedure time was 110±63min,fluoroscopy time was 43±29min and energy application was 6±4 times. This results show that RFCA in patients with congential heart diseases and arrhythymias is both safe and effective,there is no significant difference in operation,total procedure time,flouroscopy time and enery application between Ebstein's anomaly and normal heart group.
