【摘要】 目的:探讨三维电场导航系统(NavX)非透视引导下导管消融术(RFCA)治疗阵发性室上性心动过(PSVT)速的可行性。方法:对42例PSVT患者,在NavX系统非透视引导下行RFCA。结果:42例PSVT,其中房室结折返性心动过速(AVNRT)22例、房室折返性心动过速(AVRT)20例(右侧旁道4例,左侧旁道15例,左、右侧双旁道1例),全部消融成功,无严重并发症发生。前8例为验证消融靶点位置行数秒X线透视,1例患者左锁骨下-奇静脉迂曲畸形,行静脉造影,1例左前隐匿性旁道非透视引导下消融未成功,改在透视下消融,更换合适消融导管消融成功,X线曝光时间6分钟,其余患者手术全程在非透视下完成。结论:NavX非透视引导下RFCA是可行的。多数患者手术全程可在非透视下完成。更多还原

【Abstract】 Objective:To assess the feasibility of nonfluoroscopic radiofrequency catheter ablation(RFCA) for paroxysmal supraventricular tachycardia (PSVT) guided by tri-dimensional electronic navigation system(NavX).Method: 42 patients treated by RFCA with NavX,which consist of 22 AVNRT and 20 AVRT.Result:All patients were successful without serious complications.Initial 8 cases of patients using of fluoroscopy were required to validate the location of ablation,1 case had to radiography because of deformation of left sub-clavicle vein,1 case of left AVRT was finally ablated with 6 minutes X-ray fluoroscopy,the other patients had 0 fluoroscopy.Conclusions:nonfluoroscopic RFCA for PSVT with NavX is feasible更多还原
