目的评价Carto三维标测系统指导行射频消融治疗心房纤颤的疗效。方法 16例房颤患者,术中采用Carto三维标测系统结合肺静脉造影重塑左心房和肺静脉模型,定位肺静脉前庭开口及其周围出现呈现出双电位或复合电位的靶位点,在环状电极标测下,分别沿肺静脉前庭开口进行环状消融,并消融其周围双电位及复合高频电位处,直至双侧肺静脉内电位完全隔离。结果 16例患者术后达到完全肺静脉内电位隔离,所有患者术中均无并发症发生。但有2例术后复发。结论在Carto三维标测系统指导下的肺静脉前庭环状消融治疗房颤安全有效。
Objective To evaluate the curative effect of Carto 3-D mapping system guided by radiofrequency catheter ablation on atrial fibrillation. Methods Sixteen patients with atrial fibrillation were treated with carto-dimensional mapping system combined with pulmonary vein angiography to remodel the left atrium and pulmonary vein. Sixty-two patients with atrial fibrillation were located at or near the vestibular vestibular velum of the pulmonary veins. The mapping, respectively, along the vestibular vestibule pulmonary vein ablation, ablation and its surrounding double potentials and complex high-frequency potential, until the bilateral pulmonary venous potential was completely isolated. Results Sixteen patients achieved complete pulmonary venous potential isolation after operation, and no complications occurred during operation in all patients. However, there were 2 cases of recurrence. Conclusions Atrial fibrillation is safe and effective under the guidance of Carto 3D mapping system.
