摘要

背景:三维电解剖图(EAM)系统可以在不进行透视的情况下对室性早搏(PVC)患者实施导管消融(CA)。右心室流出道(RVOT)位置有利于进行零荧光透视 CA。非 RVOT 的零荧光 CA 是一项具有挑战性的手术。该研究旨在评估在RVOT和非RVOT的PVC患者中使用EAM进行零荧光CA的有效性和安全性:方法:在EAM引导下,对107例PVCs患者进行了完全零荧光CA。54名患者接受了RVOT零荧光CA检查。其余 53 名患者接受了零荧光镜非 RVOT CA。人口统计学和临床基线特征、手术参数和随访均来自医疗记录。主要结果是急性和永久成功率(12个月随访)、并发症和手术时间:结果:各组的基线特征无明显差异。RVOT零荧光CA组有52名患者(94.44%)获得了急性手术成功,非RVOT零荧光CA组有45名患者(86.54%)获得了急性手术成功(ns)。RVOT零荧光CA组有50名患者(90.74%)获得了长期成功,非RVOT零荧光CA组有44名患者(84.62%)获得了长期成功(无)。RVOT组的中位手术时间为80.5分钟,非RVOT组为90分钟(无)。非RVOT组有两例并发症(无):结论:RVOT和非RVOT位置的零氟镜消融术在手术时间、疗效和安全性方面没有差异。PVC的无氟CA是一种可行、安全且高效的手术。

Zero-fluoroscopy catheter ablation of premature ventricular contractions: comparative outcomes from the right ventricular outflow tract and other ventricular sites.

Background: The three-dimensional electroanatomic mapping (EAM) system allows performing catheter ablation (CA) without fluoroscopy in patients with premature ventricular contractions (PVCs). The right ventricle outflow tract (RVOT) location is favorable for performing zero-fluoroscopy CA. Non-RVOT zero-fluoroscopy CA is a challenging procedure. The study aimed to evaluate the efficacy and safety of zero-fluoroscopy CA using the EAM in patients with PVCs from RVOT and non-RVOT.

Methods: Completely zero-fluoroscopy CA of PVCs guided by EAM was performed in 107 patients with PVCs. 54 patients underwent zero-fluoroscopy RVOT CA. The remaining 53 patients underwent zero-fluoroscopy non-RVOT CA. Demographic and clinical baseline characteristics, procedure parameters, and follow-up were obtained from medical records. Primary outcomes were the acute and the permanent success rate (12-month follow-up), complications, and procedure time.

Results: There were no significant differences between groups regarding baseline characteristics. Acute procedural success was achieved in 52 patients (94,44%) in the RVOT zero-fluoroscopy CA group and in 45 patients (86,54%) in the non-RVOT zero-fluoroscopy CA group (ns). A long-term success rate was achieved in 50 patients (90,74%) in the RVOT zero-fluoroscopy CA group and in 44 patients (84,62%) in the non-RVOT zero-fluoroscopy CA group (ns). The median procedure time was 80.5 minutes in the RVOT group and 90 minutes in the non-RVOT group (ns). There were two complications in the non-RVOT group (ns).

Conclusions: There were no differences in procedure time efficacy and safety zero-fluoroscopy ablation between RVOT and non-RVOT locations. Non-fluoroscopy CA of PVCs is a feasible, safe, and efficient procedure.
