D. Fatkin et al., ACCURACY OF BIPLANE TRANSESOPHAGEAL ECHOCARDIOGRAPHY IN DETECTING LEFT ATRIAL THROMBUS, The American journal of cardiology, 77(4), 1996, pp. 321
Biplane transesophageal echocardiography (TEE) had a high sensitivity
and specificity, but a low positive predictive accuracy for the detect
ion of left atrial thrombus in 60 patients who underwent mitral valve
surgery. The high false-positive rate observed in this study appears t
o reflect the difficulty in differentiating severe spontaneous echo co
ntrast from thrombus on TEE.
