Objective To evaluate live three dimensional transthoracic echocardiography (Live 3D TTE) for the detection of left atrial appendage thrombus(LAAT). Methods This is a prospective protocol recruiting 26 cases with mean age(61±7) years. Each patient received Live 3D TTE examination before transesophageal echocardiography (TEE). The images were analyzed with double blind rules. The results of Live 3D TTE were evaluated by the golden standard of TEE results. Results The sensitivity, specificity, accuracy, positive predictive value and negative value of Live 3D TTE were 73%, 60%,65%,57%,75% respectively. There was a good agreement of interobserver variation (Kappa= 0.468 ,P 0.05 ) and excellent agreement of intraobserver variation (Kappa= 0.769 ,P 0.0001 ).Conclusions Live 3D TTE is a non invasive, less torture modality with good reproduction.With the primary comparison of TEE result, it showed relative high sensitivity and negative predictive value.
