目的介绍压力导管、可建模环形电极导管等新操作环境下CartoM erge技术的使用经验。方法共纳入24例阵发性心房颤动患者,分为CartoM erge组(实验组,n=16)和常规方法组(对照组,n=8),实验组通过环形电极导管构建肺静脉结构后与电子计算机X射线断层扫描(CT)图像融合,对照组不进行CT融合。两组均采用压力导管进行双侧肺静脉隔离。采集两组患者的一般资料、建模时间、左/右侧肺静脉隔离时间、总手术时间、X线曝光时间、放电时间、左/右侧肺静脉一次隔离成功率、术后窦性心律维持率,比较两组之间的差异。结果两组患者一般资料无统计学差异,实验组的建模时间[(5.4±1.6)min vs(11.6±2.4)min]、总手术时间[(68.3±13.9)min vs(148.8±43.9)min]、左/右侧肺静脉隔离时间、X线曝光时间、放电时间均短于对照组,左/右侧肺静脉一次隔离成功率高于对照组(左侧:14/16 vs 2/8;右侧:16/16 vs 4/8),两组术后3个月和6个月窦性心律维持率之间无统计学差异(术后3个月:12/16 vs 5/8;术后6个月:9/12 vs 3/5)。结论在新的操作环境下,与常规方法相比,CartoM erge技术能够缩短手术时间和X线曝光时间,提高即刻消融成功率。
Objectives To introduce the experience of using CartoMerge technology in new operating environments such as pressure catheters and modeled loop lead catheters. Methods A total of 24 patients with paroxysmal atrial fibrillation were enrolled in the study. They were divided into Carto-erge group (n = 16) and conventional group (n = 8) Computerized tomography (CT) images were fused, while control groups were not CT-fused. Two groups were used pressure catheter for bilateral pulmonary vein isolation. General data, modeling time, left / right pulmonary vein isolation time, total operation time, X-ray exposure time, discharge time, success rate of left / right pulmonary vein isolation, postoperative sinus rhythm maintenance rate, Compare the differences between the two groups. Results There was no significant difference in the general data between the two groups. The modeling time of the experimental group [(5.4 ± 1.6) min vs (11.6 ± 2.4) min], total operative time [(68.3 ± 13.9) min vs (148.8 ± 43.9) min ], Left and right pulmonary vein isolation time, X-ray exposure time, discharge time were shorter than the control group, left / right pulmonary vein isolation success rate was higher than the control group (left: 14/16 vs 2/8; right : 16/16 vs 4/8). There was no significant difference in the maintenance rate of sinus rhythm between the two groups at 3 months and 6 months after operation (3 months: 12/16 vs 5/8; postoperative 6 Month: 9/12 vs 3/5). Conclusion In the new operating environment, CartoMerge technology can shorten the operation time and X-ray exposure time and improve the success rate of immediate ablation compared with conventional methods.
