What are the prognostic implications of left atrial spontaneous echo contrast in nonvalvular atrial fibrillation?
The prognostic implications of left atrial spontaneous echo contrast in nonvalvular atrial fibrillation have been studied in the J Am Coll Cardiol. 1994 article by Leung et al. The study concluded that left atrial spontaneous echo contrast was associated with an increased risk of thromboembolic events in patients with nonvalvular atrial fibrillation. The study further suggested that patients with left atrial spontaneous echo contrast should be managed more aggressively for thromboprophylaxis.
