Spontaneous echo contrast signals higher thromboembolic risk in AF and MS; leaves open its independent role guiding anticoagulation beyond standard criteria.
Does left atrial spontaneous echo contrast predict left atrial thrombus or suspected embolism in patients undergoing transesophageal echocardiography?
Left atrial spontaneous echo contrast on transesophageal echocardiography is a significant marker of blood stasis and previous thromboembolism in patients with atrial fibrillation or mitral valve disease.
Black et al. (1991) studied this question.
