心内直视术同期行改良迷宫射频消融术治疗心房纤颤

The treatment of atrial fibrillation by modified MAZE procedure during concomitant open heart surgeries

目的探讨心内直视术同期行改良迷宫射频消融手术治疗心房纤颤(AF)的疗效。方法回顾性分析16例接受心脏直视手术患者,同期用单极冲洗式射频消融行改良迷宫术治疗AF。结果术毕为窦性心律SR15例,1例仍为AF。无Ⅲ°房室传导阻滞、无心脏穿孔和死亡。随访1日至5年,14例为SR,3例为AF。结论单极冲洗式射频消融改良迷宫术治疗AF是一简易、安全、有效的方法。

Objective To evaluate the effects of modified MAZE procedure using irrigated radiofrequency to treat the atrial fibrillation. Methods The retrospective analysis was used for 15 eases with the atrial fibrillation who were treated by modified MAZE proeedure using irrigated radiofrequeney during concomitant open heart surgeries. Results There were no Ⅲ°trial ventrieular block, cardiac perforation and death in the 15 patients. After the operation, 14 patients witll atrial fibrillation were rebounded to sinus rhythm and 1 patient remained the atrial fibrillation. Conclusion The modified MAZE procedure using irrigated radiofrequency is an effective method to treat the atrial fibrillation.
