单导管射频消融治疗A型预激综合征并阵发性室上性心动过速28例

Comparative study of single radiofrequency catheter ablation of type A Wolff-Parkinson-White syndrome and paroxysmal supraventricular tachycardia

目的:探讨单导管射频消融A型预激综合征并阵发性室上性心动过速的可行性及安全性。方法:对照组行常规射频消融术,术中共放置动脉鞘管(锁骨下静脉1根,股静脉2根,股动脉1根)4根,需要电极4根;观察组利用常规体表12导联心电图及冠状窦体表投影定位的外置冠状窦电极,穿刺股动脉放置动脉鞘管1根,仅需要一根消融大头电极导管。记录手术的消毒置管时间、标测消融总时间、放电时间、射线照射量、旁道电位例数、射频消融成功例数、并发症例数及复发例数。结果:所有病例均成功消融,无严重并发症。手术的消毒穿刺时间观察组短于对照组,有统计学差异;标测消融总时间、放电时间、射线照射量、旁道电位例数、射频消融成功例数、并发症例数及复发例数均无统计学差异。结论:单导管射频消融A型预激综合征并阵发性室上性心动过速简单有效、安全可行。

Objective： To investigate the single radiofrequency catheter ablation of type A Wolff-Parkin son-White syndrome and paroxysmal supraventricular tachycardia beckoning the feasibility and safety. Methods.. the control group received conventional radiofrequency ablation, with the placing of artery sheath catheter （ 1 subclavian vein, femoral vein 2, femoral artery 1 ） 4, 4 observation group to electrode; using conventional surface 12 lead ECG and coronary sinus body surface projection war positioned external coronary sinus electrode, puncture of femoral artery placement of arterial sheath tube 1, only need one big electrode catheter ablation. Recording operation disinfeclion indwelling time, ablation of total time, discharge time, radiation exposure, accessory pathway potential cases, successful radiofrequency ablation in cases of complications, cases and cases of relapse. Results： all cases were successful ablation, without severe complications. Operation disinfection puncture time were shorter than the control group, there was statistically significant difference; ablation of total time, discharge time, radiation exposure, acces sory pathway potential cases, successful radiofrequency ablation in cases of complications, cases and cases of relapse showed no statistical difference. Conclusion： single radiofrequency catheter ablation of type A Wolff-Parkinson- White syndrome and paroxysmal supraventricular tachycardia heartbeat is simple and effective, safe and feasible.
