【摘要】：目的通過與常規(guī)X線二維指導(dǎo)下行導(dǎo)管消融對比,評估Carto 3三維標測系統(tǒng)指導(dǎo)下完全零射線單導(dǎo)管射頻消融治療右室流出道室早(RVOT-VPC)的有效性及安全性。方法分析2015年4月至2017年3月收治的擬行導(dǎo)管射頻消融治療的右室流出道室早患者25例,其中三維組13例,完全零射線,運用Carto 3三維標測系統(tǒng)指導(dǎo)下進行建模、指導(dǎo)標測及消融;二維組12例,采用傳統(tǒng)常規(guī)X線二維指導(dǎo)下進行標測和消融。比較兩組的標測時間、放電次數(shù)、手術(shù)成功率、手術(shù)時間、X線曝光時間及并發(fā)癥發(fā)生率。結(jié)果兩組患者手術(shù)成功率比較差異無統(tǒng)計學(xué)意義,即刻手術(shù)成功率均為100%,遠期成功率二維組與三維組分別為91.6%、92.3%(P=0.953)。與二維組相比,三維組在標測時間(14.8±4.3 vs.4.5±2.2,P=0.000)、手術(shù)時間(63.8±3.9 vs.54.4±4.6,P=0.000)、放電次數(shù)(5.7±2.3 vs.3.4±1.0,P=0.003)均明顯減少,三維組術(shù)中完全零射線,差異有統(tǒng)計學(xué)意義。結(jié)論與傳統(tǒng)X線二維指導(dǎo)下對比,三維標測系統(tǒng)指導(dǎo)下標測時間、手術(shù)時間、放電次數(shù)明顯減少,并可以完全零射線暴光;Carto 3三維標測系統(tǒng)指導(dǎo)下行全零射線單導(dǎo)管射頻消融治療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.
