| 目的：介绍应用CartoMerge技术将左心房和肺静脉CT三维重建图像与Carto电解剖标测图像相整合，指导肺静脉前庭电解剖隔离治疗心房颤动的初期经验。方法：对13例阵发性和2例持续性房颤患者，应用CartoMerge技术进行肺静脉前庭电解剖隔离。结果：消融前左心房各壁标测点为（103±13）个；图像融合后，点与面之间的配准距离为（1.8±0.2） mm；环左肺静脉消融点（66±15）个，环右肺静脉消融点（58±20）个；所有患者均达到肺静脉电隔离；手术时间（305±45） min，透视时间（52±18） min；术中、术后无并发症发生。结论：CT三维重建后的图像接近真实解剖，与Carto电解剖标测图像的整合图像可帮助术者校正和弥补Carto电解剖图像的不足，有助于提高手术成功率，减少并发症。 |

| Abstract: |
| Objective：To summarize our initial experience on threedimensional electroanatomic mapping with CartoMerge, so as to provide evidence for guiding catheter ablation of atrial fibrillation (AF). Methods: Fifteen patients with paroxysmal/persistent AF (13 paroxysmal and 2 persistent), who were to receive catheter ablation, were analyzed by CARTOMERGE, which combines computed tomography (CT) angiography, picture merging, guiding ablation, etc. Results: There were 103±13 mapping points before ablation, with 66±15 in the left ablation circle and 58±20 in the right. The distance between points and surface was (1.8±0.2) mm in the merged images. Operation time was (305±45) min and the Xray exposure time was (52±18) min. Isolation of pulmonary veins potential was achieved in all patients and there was no complication during the operation. Conclusion: Threedimensional CT images is very close to the the real anatomy of left atrium and pulmonary veins. Cartomerge technique can overcome some shortcomings of Carto electroanatomic mapping pictures, which can improve the successful rate of operation and reduce complications. |
