Implication
Electroanatomical LA remodeling associates with higher stroke risk in AF; hypothesis-generating for voltage mapping and should not yet change practice.

Population
348 patients with non-valvular atrial fibrillation (215 paroxysmal, 133 persistent) who underwent catheter ablation, mean age 55.4, 78.4% male.

Outcome
Relationship between CHADS2/CHA2DS2VASc score (0, 1, ≥ 2) or events of stroke and mean/regional LA volume (by 3D computed tomography) or LA endocardial voltage (by 3D-electroanatomical map)surrogate
Electroanatomical remodeling of the left atrium, characterized by increased volume and decreased endocardial voltage, is significantly associated with higher CHADS2/CHA2DS2VASc scores and a history of stroke in patients with non-valvular atrial fibrillation.
