Remote magnetic navigation (RMN) is often used in combination with a 3-dimensional mapping system to perform catheter ablations. This study aim to investigate the feasibility and effectiveness of a novel 3D-mapping system, EnSite Precision, combined with RMN for catheter ablation of premature ventricular contractions (PVCs), and compared it to the procedures performed by CARTO3 with RMN.
Forty-three consecutive PVC patients were either ablated with the guidance of EnSite Precision (n = 22) or CARTO (n = 21) navigated by RMN. Procedure-related details, acute and long-term success were assessed.
Patient characteristics between both the groups were similar (age: 47.1 ± 19.8 vs 47.1 ± 12.7, female: 63.6% vs 57.1%). No significant difference was found in the procedure time (99.5 ± 30.4 vs 92.9 ± 24.8 min, =0.436), mapping time (18.6 ± 12.8 vs 15.5 ± 10.2 min, =0.390), radiofrequency ablation time (333.4 ± 267.0 vs 469.3 ± 343.1 s, =0.154), fluoroscopy time (4.0 ± 1.9 vs 3.8 ± 2.0 min, =0.635), and X-ray dose (1.8 ± 1.4 vs 2.0 ± 1.2 Gycm, =0.649) between the two groups. No significant procedural complication occurred in either group. In addition, there was no significant differences regarding the acute success rate (90.9% vs 90.5%, =0.961) and long-term success rate (86.4% vs 81.0%, =0.631) after 16.2 ± 6.2 months of follow-up between the two groups.
RMN combined with EnSite Precision mapping system is effective and safe for catheter ablation of PVCs.
远程磁导航（RMN）常与三维标测系统联合用于导管消融。本研究旨在探讨新型三维标测系统EnSite Precision联合RMN用于室性早搏（PVC）导管消融的可行性和有效性，并将其与采用CARTO3联合RMN进行的手术进行比较。
连续43例PVC患者，分别在EnSite Precision（n = 22）或CARTO（n = 21）引导下，由RMN进行消融。评估与手术相关的细节、急性和长期成功率。
两组患者的特征相似（年龄：47.1±19.8岁 vs 47.1±12.7岁，女性：63.6% vs 57.1%）。两组在手术时间（99.5±30.4分钟 vs 92.9±24.8分钟，P = 0.436）、标测时间（18.6±12.8分钟 vs 15.5±10.2分钟，P = 0.390）、射频消融时间（333.4±267.0秒 vs 469.3±343.1秒，P = 0.154）、透视时间（4.0±1.9分钟 vs 3.8±2.0分钟，P = 0.635）和X线剂量（1.8±1.4 Gycm vs 2.0±1.2 Gycm，P = 0.649）方面均无显著差异。两组均未发生明显的手术并发症。此外，两组在随访16.2±6.2个月后的急性成功率（90.9% vs 90.5%，P = 0.961）和长期成功率（86.4% vs 81.0%，P = 0.631）方面也无显著差异。
RMN联合EnSite Precision标测系统用于PVC导管消融是有效且安全的。
