      catheter ablation for ventricular tachycardia.

AB  - AIMS: Remote magnetic navigation (RMN) is a safe and effective means of 
      performing ventricular tachycardia (VT) ablation. It may have advantages over 
      manual catheter ablation due to ease of manoeuvrability and catheter stability. 
      We sought to compare the safety and efficacy of RMN vs. manual VT ablation. 
      METHODS AND RESULTS: Retrospective study of procedural outcomes of 139 
      consecutive VT ablation procedures (69 RMN, 70 manual ablation) in 113 patients 
      between 2009 and 2015 was performed. Remote magnetic navigation was associated 
      with overall higher acute procedural success (80% vs. 60%, P = 0.01), with a 
      trend to fewer major complications (3% vs. 9% P = 0.09). Seventy-nine patients 
      were followed up for a median of 17.0 [interquartile range (IQR) 3.0-41.0] months 
      for the RMN group and 15.5 (IQR 6.5-30.0) months for manual ablation group. In 
      the ischaemic cardiomyopathy subgroup, RMN was associated with longer survival 
      from the composite endpoint of VT recurrence leading to defibrillator shock, 
      re-hospitalization or repeat catheter ablation and all-cause mortality; 
      single-procedure adjusted hazard ratio (HR) 0.240 (95% CI 0.070-0.821) P = 0.023, 
      multi-procedure HR 0.170 (95% CI 0.046-0.632) P = 0.002. In patients with 
      implanted defibrillators, multi-procedure VT-free survival was superior with RMN, 
      HR 0.199 (95% CI 0.060-0.657) P = 0.003. CONCLUSION: Remote magnetic navigation 
      may improve clinical outcomes after catheter ablation of VT in patients with 
      ischaemic cardiomyopathy. Further prospective clinical studies are required to 
      confirm these findings.
