摘要
目的探索使用三维电解剖指导阵发性室上性心动过速(PSVT)射频消融方法的可行性及效果。方法选择连续入院行射频消融的PSVT患者共47例,分为两组,三维组使用CARTO 3三维电解剖系统指导消融(n=26),常规组使用X线指导消融(n=21),比较两组X线透视时间、X线用量等的差异。结果三维组X线透视时间明显少于二维组[(81±84)s vs(1 124±405)s,P<0.01],相应的X线用量也大为减少[(97±105)mGy vs(1628±555)mGy,P<0.01]。三维组14例房室结双径路患者中,有9例(64%)完全无X线透视。所有病例均手术成功,无明显并发症。结论三维电解剖指导PSVT射频消融是安全和有效的,可以显著减少X线透视,部分可实现完全无X线透视完成消融手术。
Objective To explore the feasibility and effectiveness of catheter ablation of paroxysmal supraventficular tachycardia（PSVT） guided by CARTO 3 electroanatomical navigation system. Methods Forty-seven patients with PSVT underwent catheter ablation were divided into two groups, 3D group using CARTO 3 guide ablation （n = 26）, the conventional group using X-Ray guide ablation （n= 21 ）. X-ray fluoroscopy time, X-ray fluoroscopy exposure were compared in two groups. Results Fluoroscopy time of CARTO 3 group was less than that of X-Ray group [ （81 ±84） s vs （ 1 124 ±405 ） s, P〈0.01 ] , with a correspondingly low radiation exposure [ （ 97± 105 ） mGy vs （ 1 628 ±555 ） mGy, P〈 0.01 ] . In 9/14（64% ） atrioventricular nodal reentry tachycardia （AVNRT） cases, electroanatomical mapping avoided fluoroscopy entirely. All procedures were acutely successful , and without incurring in any major complication. Con- clusion Using 3 D electroanatomical navigation system （ CARTO 3 system） in supraventrieular arrhythmia ablation is ef- fective and safe,it can markedly reduce fluoroscopy exposure. In many cases, non-fluoroscopic RFCA is feasible.
