Key result
Remote magnetic catheter navigation for atrial fibrillation ablation resulted in similar freedom from AF at 6 months compared to manual navigation (57.8% vs 66.4%, P=0.196).

Supports consideration of remote magnetic navigation as alternative; hypothesis-generating and should not yet change practice.
Case-Control (n=356)
Does remote magnetic catheter navigation improve freedom from atrial fibrillation at 6 months compared to manual catheter navigation in patients undergoing catheter ablation?
Absolute Event Rate: 57.8% vs 66.4%
p-value: p=0.196
Remote magnetic catheter navigation for AF ablation is safe and effective, offering shorter fluoroscopy times but longer procedure times compared to manual navigation, with no significant difference in 6-month freedom from AF.
Arya et al. (2010) conducted a case-control in Atrial fibrillation (n=356). Remote magnetic catheter navigation (RMN) vs. Manual catheter navigation (MCN) was evaluated on Freedom from AF at 6 months (p=0.196). Remote magnetic catheter navigation for atrial fibrillation ablation resulted in similar freedom from AF at 6 months compared to manual navigation (57.8% vs 66.4%, P=0.196).
