Negative 2D echo results should not exclude left atrial thrombus in mitral stenosis; leaves open need for transesophageal confirmation in prospective studies.
Does two-dimensional echocardiography accurately detect left atrial thrombus in patients with mitral stenosis?
Two-dimensional echocardiography has high specificity but moderate sensitivity for detecting left atrial thrombi in patients with mitral stenosis, frequently missing thrombi confined to the left atrial appendage.
Chiang et al. (1987) studied this question.
