目的：旨在研究是否可以在没有透视的情况下通过经房间隔穿刺部位在右心房和左心房之间准确地切换消融导管。研究方法：40例持续性房颤患者（平均年龄60.2±7.4岁，65%为男性）按1：1的比例随机分为两组，一组在透视引导下经房间隔穿刺（无轨组），另一组在Carto3系统标测的轨迹图像引导下经房间隔穿刺（轨迹组）。结果：轨迹三维图像映射平滑，显示清晰。两组的成功率无显著差异（100% vs. 100%，p>0.05）。然而，轨道组在没有任何X线透视的情况下完成了穿过间隔的手术，这表明手术时间比无轨组短（4±3 s vs. 20±10 s，p<0.01）。结论：使用Carto3系统可视化通过穿刺部位的轨迹，可以在零透视的情况下引导消融导管快速安全通过房间隔内。
Objective: To investigate whether switching the ablation catheter between the right and left atria through transseptal puncture site can be accurately performed without fluoroscopy. Methods: Forty patients with persistent atrial fibrillation (mean age, 60.2±7.4 years; 65% males) got “2C3L” approach were randomized in a 1:1 ratio to undergo either crossing interatrial septum guided by fluoroscopy (trackless group) or crossing septum guided by track image that was mapped by Carto3 system (track group). Results: The three-dimensional image of the track could be mapped smoothly and shown clearly. No significant differences were found in the success rates between the two groups (100% vs. 100%, p>0.05). However, the procedure of crossing septum was completed without any fluoroscopy use in track group, which showed a shorter procedure time than trackless group (4±3 s vs. 20±10 s, p<0.01). Conclusion: Visualizing the track passing through the puncture site using Carto3 system can guide the ablation catheter in safely crossing the intra-atrial septum quickly with zero fluoroscopy.
