Abstract Objective To evaluate the predictive value of esophageal echocardiography in patients with atrial fibrillation in patients with atrial fibrillation. Methods A total of 148 patients with atrial fibrillation admitted to the Liuzhou Workers′ Hospital from October 2012 to January 2018 were selected and divided into thrombus group (22 cases) and the non-thrombotic group (126 cases). Trans-esophageal echocardiography and enhanced CT were performed in all patients, and echocardiographic parameters of two groups were observed. As clinical diagnosis was "gold standard", true positive rate, false positive rate, true negative rate, false negative rate, sensitivity, specificity and accuracy of the two examinations in the diagnosis of atrial appendage thrombosis were analyzed. Results Left atrial appendage maximal area (LAA-max) of diastole and the left atrial appendage minimum area (LAA-min) of paradoxical expansion in thrombus group were significant higher than that in non-thrombus group (P < 0.05). There was no statistically significant in the left atrial appendage width (LAA-D) and left atrial appendage length (LAA-L) of two groups (P > 0.05). True positive rate and true negative rate, diagnosis of atrial fibrillation by trans-esophageal echocardiography were 90.91% (20/22) and 90.48% (114/126) respectively, which were apparently higher than those of enhanced CT [63.64% (14/22), 61.90% (78/126), all P < 0.05]. The sensitivity, specificity and accuracy of trans-esophageal echocardiography in diagnosing atrial fibrillation with left atrial appendage thrombosis were 90.91%, 90.48% and 90.54%, which were significantly higher than those of enhanced CT examination (63.64%, 61.90%, 62.16%, all P < 0.05). Conclusion LAA-max and LAA-min were abnormally elevated in atrial fibrillation patients with left atrial appendage. Transesophageal echocardiography has a good predictive value for left atrial appendage thrombosis in patients with atrial fibrillation.
