RMN may not match manual navigation for AF ablation success; leaves open whether technique, sheath use, or bias explains the difference in this Level 4 study.
Case-Control (n=140)
Does remote magnetic catheter navigation improve time to first recurrence compared to manual catheter navigation in patients undergoing ablation for atrial fibrillation?
Absolute Event Rate: 40% vs 59.1%
p-value: p=0.031
Manual catheter navigation using a steerable sheath may result in a higher rate of freedom from AF recurrence compared to remote magnetic navigation, particularly in persistent AF, though RMN is associated with shorter fluoroscopy times and potentially fewer pericardial effusions.
Koutalas et al. (2014) conducted a case-control in atrial fibrillation (n=140). remote magnetic catheter navigation (RMN) vs. manual catheter navigation (MCN) using steerable sheath was evaluated on time to first recurrence after index procedure (p=0.031). Remote magnetic catheter navigation was associated with a lower rate of freedom from atrial fibrillation recurrence compared to manual catheter navigation (40% vs. 59.1%, P=0.031).
