射频消融治疗阵发性室上性心动过速35例分析

Analysis of Radiofrequency Catheter Ablation for the treatment in 35 cases of Paroxysmal Supraventricular Tachycardia

目的总结射频消融(RFCA)治疗阵发性室上性心动过速(PSVT)35例的经验。方法左房室旁路消融二尖瓣室侧,右侧房室旁路消融三尖瓣房侧;房室结双径路通过下位法能量递增消融法改良房室结。结果19例房室折返型心动过速,左侧旁道13条,右侧旁道6条,16例房室结折返型心动过速(AVNRT)首次消融均成功。术后1周1例AVNRT复发,再次消融成功。1～20个月随访无复发及严重并发症。结论RFCA治疗PSVT安全、有效。

Objective To sum up the experience of the mdiofrequeney catheter ablation for the treatment in 35 eases of paroxysmal supraventricular tachycardia. Methods Left accessory pathway ablation in the side of ventricle of mitral valve, right accessory pathway ablation in the side of atrium of tricuspid valve. Results First success was achieved in 19 cases of AV reentrant tachycardia（13 left,6 right ccessory pathway ） and 16 AV nodal reentrant tachycardia. 1 case of AV nodal reentrant tachycardia recurred 1 week after, but it was ablated successfully again. No other case relapsed. There was no severe implication. Conclusion Radiofrequency catheter ablation appears to be effective and safe in treatment of paroxysmal supraventricular tachycardia.
