Additional value of left atrial appendage geometry and hemodynamics when considering anticoagulation strategy in patients with atrial fibrillation with low CHA2DS2-VASc scores

Even in patients with low CHA2DS2-VASc scores, the presence of both decreased LAA flow velocity and increased LAA orifice size was associated with a high odds ratio of stroke. Future large prospective studies are needed to assess whether these patients should receive anticoagulants.
