Abstract:Background: The optimal ablation strategy for persistent atrial
fibrillation (PsAF) remains to be defined. We sought to compare very
long-term outcomes between linear ablation and electrogram (EGM)-guided
ablation for PsAF. Methods: In a retrospective analysis, long-term
arrhythmia-free survival compared between two propensity-score matched
cohorts, one with pulmonary vein isolation (PVI) and linear ablation
including roof/mitral isthmus line (LINE-group, n=52) and one with PVI
and EGM-guided ablation (EGM-gro… Show more
