简介
Background
In patients with atrial fibrillation (AF), left atrial appendage (LAA) morphology has been suggested to modify risk of thromboembolic events (TEs).
Objective
In this study, we tested the hypothesis that a TE after AF catheter ablation is associated with LAA characteristics.
Methods
Of 2069 patients included in the Leipzig Heart Center AF Ablation Registry, 15 (0.7%) suffered a TE (excluding events within 30 days) during follow-up (ie, 3.078 patient-years). Those patients were matched for CHA2DS2-VASc criteria with 115 patients without TE, and computed tomography (n = 120) or magnetic resonance imaging (n = 10) data were also compared. LAA volume, morphology (cactus, chicken-wing, windsock, and cauliflower), and takeoff (higher/lower) in relation to the adjacent pulmonary vein were determined.
Results
After patients were followed for a median period of 24 months, 67% of the patients remained in …
