Does FIRM ablation improve freedom from AF in patients with atrial fibrillation?
FIRM-guided ablation for atrial fibrillation demonstrates a rapid learning curve, achieving approximately 80% freedom from AF at 1 year even at newly adopting centers.
Elimination of patient-specific AF rotors/focal sources produced freedom-from-AF of ≈80% at 1 year at centers new to FIRM. FIRM-guided ablation has a rapid learning curve, yielding similar results to original FIRM reports in each center's first cases.
Miller et al. (2014) studied this question.
