At 3.5 years post ablation, AF-free rates were 42% in the RMN group vs. 30% in the Manual group (survival analysis p < .05), and clinically effective rates were 70% vs. 49% (survival analysis p < .005).

Overview

Latest RMN system linked to shorter fluoroscopy and higher long-term AF-free rates versus manual; leaves open whether RCTs will confirm superiority.

Structured PICO

Does remote magnetic catheter navigation improve long-term AF-free rates compared to manual navigation in patients undergoing atrial fibrillation ablation?

P
Population
214 patients with atrial fibrillation (112 in RMN group: 78 paroxysmal, 34 persistent; 102 in Manual group: 72 paroxysmal, 30 persistent)
I
Intervention
Remote magnetic (RMN) catheter navigation for atrial fibrillation ablation
C
Comparator
Manual catheter navigation technique for atrial fibrillation ablation
O
Outcome
AF-free rates and clinically effective rates at 1 year, 2 years, and 3.5 years post ablation

The current generation of remote magnetic navigation for atrial fibrillation ablation is associated with improved long-term AF-free and clinically effective rates compared to manual navigation.
