Carto-Merge指导下导管消融治疗阵发性房颤的初步体会

Initial experience of paroxysmal atrial fibrillation ablation guided by Carto-Merge

目的运用16排螺旋CT图像与CARTO三维电解剖标测整合技术（Carto-Merge）指导阵发性房颤的导管消融治疗。方法32例经抗心律失常药物治疗效果欠佳的患者进行手术，其中6例患者术前1～3d行16排CT心脏成像检查，术前将CT导入有Carto-Merge的软件包进行三维重建，重建后在Carto-Merge指导手术。结果所有患者均顺利完成手术，未发生手术并发症。Carto-Merge整合误差为（1．8±0．62）mm，使用Carto-Merge患者平均手术时间为（98±28）min，X线曝光时间为（26±11）min；未使用Carto-Merge患者手术时间为（112±42）min，X线曝光时间为（35±17）min。结论使用图像融合技术可以缩短手术及X线曝光时间，提高手术的效率及安全性。

Objective To investigate the effectiveness and advantages of the Carto-Merge technique in guiding catheter ablation of paroxysmal atrial fibrillation. Methods Thrity-two patients were treated and 6 patients finished 16 slice CT image 1-3d before ablation. 16-slice CT scan combined with Carto image was performed ：by using Carto-Merge software and guiding ablation. Results All patients were successfully achieved the endpoint of ablation. All Carto-Merge patients with an error of （1.8 ± 0. 62）mm. The mean procedure time was （98±28）min in Merge group and （112±42）min in no-Merge group. The X-ray exposed time was （26± 11）min in Merge group and （35 ±17）min in no-Merge group. Conclusion Carto Merge technique can shorten the ablation and X- ray exposed time, also improve safety and effectiveness.
