零射线房间隔穿刺术治疗室性早搏的疗效分析

Analysis of the effect of zero-ray atrial septal puncture in the treatment of ventricular premature beat

摘要:

目的 分析无射线和有射线射频消融治疗室性早搏（PVBs）的差异。方法 收集98 例频发 PVBs 患者，包括右室流出道和非右室流出道类型。在二维和三维CARTO 系统操作下，根据是否使用X 射 线分为二维射线组（A 组）、三维射线组（B 组）和无射线组（C 组）。分析3 种手术方式在手术时间、放置 电极时间、标测靶点时间、放电次数、曝光时间、手术并发症及成功率方面的差异。结果 A 组手术时间长 于B、C 组，B 组长于C 组（P <0.05）。A 组测靶点时间和放电次数多于B 组和C 组（P <0.05）。A 组曝光时 间长于B、C 组，B 组长于C 组（P <0.05）。3 组电极放置时间、手术并发症及成功率比较，差异无统计学意 义（P >0.05）。结论 三维系统射频方式不仅减少术中射线暴露时间和放电次数，而且进一步缩短手术时间。 且对比三维射线，三维无射线在曝光时间和缩短手术时间上更具优势，其还取决于术者对手术和三维系统熟练 掌握程度。

Abstract:

Objective To analyze the difference between radial radiofrequency ablation and non-radial radiofrequency ablation in the treatment of ventricular premature beat. Methods Ninety-eight patients with frequent ventricular premature beats, including right ventricular outflow tract and non-right ventricular outflow tract types, were collected and divided into two-dimensional ray group (group A), three-dimensional ray group (group B) and non-ray group (group C) under the operation of two-dimensional and three-dimensional CARTO systems according to whether or not X-rays were used. Statistical analysis was made on whether there was any difference in operation time, electrode placement time, target time, discharge times, exposure time, operation complications and success rate among the three operation methods. Results Group A has the longest operation time, and the time of group B is longer than that of group C, and the differences are all with statistical significance (P < 0.05). The target time and discharge times of group A were more than those of group B and group C, and the difference was statistically significant (P < 0.05). The exposure time of group A was longer than that of group B and group C, while group B was longer than that of group C, and the difference was statistically significant (P < 0.05). There was no significant difference in electrode placement time, surgical complications and success rate among the three groups (P > 0.05). Conclusions The 3D system radio frequency method can not only reduce the exposure time of intraoperative radiation, but also further improve the success rate of surgery and reduce complications. Compared with the three-dimensional radiation group, the three-dimensional non-radiation group had more advantages in exposure time and surgical complications, which depended on the proficiency of the operator to the operation and the three-dimensional system.
