| Summary: | Abstract Background 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. Methods 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. Results 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, P = 0.436), mapping time (18.6 ± 12.8 vs 15.5 ± 10.2 min, P = 0.390), radiofrequency ablation time (333.4 ± 267.0 vs 469.3 ± 343.1 s, P = 0.154), fluoroscopy time (4.0 ± 1.9 vs 3.8 ± 2.0 min, P = 0.635), and X‐ray dose (1.8 ± 1.4 vs 2.0 ± 1.2 Gycm2, P = 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%, P = 0.961) and long‐term success rate (86.4% vs 81.0%, P = 0.631) after 16.2 ± 6.2 months of follow‐up between the two groups. Conclusions RMN combined with EnSite Precision mapping system is effective and safe for catheter ablation of PVCs. |
