目的：在房颤的手术治疗中，消融病灶的透壁性仍然是手术持久性的关键。在取代传统的 Maze 手术中，双极射频消融器的“盒子”病变已成为一种新技术，取代了通常的肺静脉双侧心外膜隔离。本研究的目的是描述美敦力 (Medtronic) 设备在制造“盒子”病变中的初步应用，并与文献中报道的 Flex 4/10 产生的病变进行比较。患者和方法：2004 年 2 月至 2011 年 3 月期间，58 名房颤患者使用双极射频装置对“盒子”病变进行迷宫手术。结果：停搏的心脏产生心外膜和心内膜病变。术后 3、6 和 12 个月时窦性心律率分别为 88%、94% 和 85%，术后未使用胺碘酮。结论：我们更好的射频消融成功率和窦性心律率的结果强调了利用心外膜和心内膜双极能量源以及左心房峡部线到二尖瓣进行更好的透壁性损伤的策略的重要性。
Objectives: In surgical treatment of atrial fibrillation, transmurality of the ablation lesions remains the key point of the durability of the maneuver. In the replace of the traditional Maze procedure, a “Box” lesion with bipolar radiofrequency ablator has emerged as a novel technique substituting the usual bilateral epicardial isolation of the pulmonary veins. The aim of the present study was to describe the preliminary utilization of Medtronic devices in making a “Box” lesion in comparison with that produced by Flex 4/10 reported in the literature. Patients and methods: Between February 2004 and March 2011, 58 patients with atrial fibrillation were operated on for a Maze procedure with a “Box” lesion using a bipolar radiofrequency device. Results: Epiand endocardial lesions were produced on the arrested heart. A sinus rhythm rate was 88%, 94%, and 85% at 3, 6 and 12 months, respectively with no postoperative amiodarone use. Conclusions: Our results of better radiofrequency ablation success rate and sinus rhythm rate emphasize how important is the strategy in doing a better transmurality lesion with the epiand endocardial bipolar energy source, along with the left atrial isthmus line to the mitral valve.
