【摘要】：目的通过与常规X线二维指导下行导管消融对比,评估Carto 3三维标测系统指导下完全零射线单导管射频消融治疗右室流出道室早(RVOT-VPC)的有效性及安全性。方法分析2015年4月至2017年3月收治的拟行导管射频消融治疗的右室流出道室早患者25例,其中三维组13例,完全零射线,运用Carto 3三维标测系统指导下进行建模、指导标测及消融;二维组12例,采用传统常规X线二维指导下进行标测和消融。比较两组的标测时间、放电次数、手术成功率、手术时间、X线曝光时间及并发症发生率。结果两组患者手术成功率比较差异无统计学意义,即刻手术成功率均为100%,远期成功率二维组与三维组分别为91.6%、92.3%(P=0.953)。与二维组相比,三维组在标测时间(14.8±4.3 vs.4.5±2.2,P=0.000)、手术时间(63.8±3.9 vs.54.4±4.6,P=0.000)、放电次数(5.7±2.3 vs.3.4±1.0,P=0.003)均明显减少,三维组术中完全零射线,差异有统计学意义。结论与传统X线二维指导下对比,三维标测系统指导下标测时间、手术时间、放电次数明显减少,并可以完全零射线暴光;Carto 3三维标测系统指导下行全零射线单导管射频消融治疗右室流出道室早安全有效。
[Abstract]:Objective To evaluate the efficacy and safety of radiofrequency catheter ablation of right ventricular outflow tract premature (RVOT-VPC) guided by Carto 3-D mapping system compared with conventional radiofrequency catheter ablation. There were 25 early patients, including 13 cases in the three-dimensional group, with zero-ray, using Carto-3 three-dimensional mapping system for modeling, mapping and ablation; 12 cases in the two-dimensional group, using conventional X-ray two-dimensional guidance for mapping and ablation. The mapping time, discharge times, surgical success rate, operation time, X-ray exposure time and complications were compared between the two groups. Results There was no significant difference in the success rate between the two groups. The immediate success rate was 100%. The long-term success rate was 91.6% in the two-dimensional group and 92.3% in the three-dimensional group, respectively (P = 0.953). Compared with the two-dimensional group, the mapping time was (14.8 + 4.3 vs. 4.5 + 2, P = 0.000), the operation time was (63.8 + 3.9 vs. 54.4 + 4.6, P = 0.000), and the discharge time was (P = 0.000). Conclusion Compared with the traditional X-ray two-dimensional guidance, the three-dimensional mapping system can significantly reduce the mapping time, operation time, discharge times and completely Zero-ray exposure, and the Carto-3 three-dimensional mapping system can guide the whole downward. Radiofrequency catheter ablation of right ventricular outflow tract with zero ray single catheter is safe and effective.
