Oka T, et al. - Patients with reduced left ventricular (LV) ejection fraction (EF) who underwent catheter ablation (CA) for non-paroxysmal atrial fibrillation (non-PAF) were examined for the outcomes ie, 4-year AF/atrial tachycardia (AT)-free survival rate and changes in LVEF, hemodynamics, and LA reverse remodeling at the end of a 90-day blanking period. Furthermore, the impact of early LA reverse remodeling on these outcomes was also evaluated. In comparison with patients with normal LVEF, outcomes of CA for non-PAF in patients with reduced LVEF demonstrated a comparable efficacy of CA in both of these study groups. In addition, greater LA reverse remodeling was noted in these patients, which was suggestive of an association with a reduced recurrence rate.
