Article Synopsis
  • Epicardial adipose tissue (EAT) is linked to atrial fibrillation (AF) and atrial fibrosis, but many AF patients show no signs of left atrial (LA) fibrosis. This study compared EAT levels in AF patients without LA fibrosis to matched controls without AF.
  • AF patients without LA fibrosis had significantly higher total and regional volumes of EAT compared to controls, indicating that EAT may play a role in AF development even when LA fibrosis is absent.
  • The study found no differences in EAT volumes between AF patients with and without LA fibrosis and no significant link between EAT volume and AF recurrence after catheter ablation.

Background: Atrial low-voltage areas (LVAs) in patients with atrial fibrillation increase the risk of atrial arrhythmia (AA) recurrence after pulmonary vein isolation (PVI). Contemporary LVA prediction scores (DR-FLASH, APPLE) do not include P-wave metrics. We aimed to evaluate the utility of P-wave duration/amplitude ratio (PWR) in quantifying LVA and predicting AA recurrence after PVI.

Introduction: An important substrate for atrial fibrillation (AF) is fibrotic atrial myopathy. Identifying low voltage, myopathic regions during AF using traditional bipolar voltage mapping is limited by the directional dependency of wave propagation. Our objective was to evaluate directionally independent unipolar voltage mapping, but with far-field cancellation, to identify low-voltage regions during AF.
