目的 回顾 6种特殊类型快速心律失常的导管射频消融 (RFCA)效果。方法 经导管标测和射频消融。结果 3例合并左上腔静脉干永存的阵发性室上性心动过速 (PSVT) ,均为左侧旁道 ,1次消融成功 ;2例二尖瓣狭窄患者为左侧旁道 ,行二尖瓣球囊成形术后 ,1次消融成功 ;1例合并Ebstein畸形的PSVT患者 ,为右侧旁道 ,导管消融 3个月后复发 ,再次消融成功。结论 合并心脏血管畸形的PSVT患者进行RFCA是安全、有效的。
Objective To review the results of catheter radiofrequency ablation (RFCA) of six special types of tachyarrhythmia. Methods Transcatheter mapping and radiofrequency ablation. Results Three cases of paroxysmal supraventricular tachycardia (PSVT) with left superior vena cava dry persistent all were left bypass and one ablation was successful. Two patients with mitral stenosis were left bypass and two After mitral balloon angioplasty, one ablation was successful. One patient with PSVT with Ebstein’s malformation was the right sidepass. The catheter recurred after 3 months of ablation and was ablated again. Conclusions RFCA in patients with PSVT complicated with cardiovascular malformations is safe and effective.
