Sex-Related Differences in Left Atrial Low-Voltage Areas According to CHA₂DS₂-VA Scores among Patients with Atrial Fibrillation.

ABSTRACT: (1) Background: We hypothesized that female sex would have a differential impact on left atrial (LA) low-voltage areas (LVAs) according to CHA₂DS₂-VA scores. (2) Methods: This study included 553 patients who underwent radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF). LVAs were defined as regions with bipolar peak-to-peak voltages of <0.5 mV. The proportion of LVAs was calculated by dividing the total LVA by the LA surface area. (3) Results: There was no sex-related difference in LA LVAs among patients with a CHA₂DS₂-VA scores ≤ 2. The proportion of LVAs was significantly higher in females among patients with CHA₂DS₂-VA scores of 3 or 4 (10.1 (4.7-15.1)% vs. 15.8 (9.2-32.1)%; p = 0.027). Female s
