Left atrial wall thickness is associated with the low-voltage area in patients with paroxysmal atrial fibrillation

Purpose To identify a potential morphological marker of remodeling and electrophysiological dysfunction, we investigated if low wall thickness is associated with low-voltage areas (LVAs) in the left atrium. Methods Wall thickness was measured by computed tomography and LVA (% area with bipolar volta...

Zusammenfassung:Purpose To identify a potential morphological marker of remodeling and electrophysiological dysfunction, we investigated if low wall thickness is associated with low-voltage areas (LVAs) in the left atrium. Methods Wall thickness was measured by computed tomography and LVA (% area with bipolar voltage  10% of segment surface area) was observed in 123 of 215 segments (57%). Segments in the low tertile of wall thickness (
