The spatiotemporal electrogram dispersion ablation targeting rotors is more effective for elderly patients than non‐elderly population

ABSTRACT: Abstract

Background

Modulating atrial fibrillation (AF) drivers has been proposed as one of the effective ablation strategies for non‐paroxysmal AF (non‐PAF). However, the optimal non‐PAF ablation strategy is still under debate because the exact mechanisms of AF persistence including focal activity and/or rotational activity, are not well‐understood. Recently, spatiotemporal electrogram dispersion (STED) assumed to indicate rotors in the form of rotational activity is proposed as an effective target for non‐PAF ablation. We aimed to clarify the effectiveness of STED ablation for modulating AF drivers.

Methods

STED ablation plus pulmonary vein isolation was applied in 161 consecutive non‐PAF patients not undergoing previous ablation. STED areas within the entire left and r
