Abstract：Objective To observe the diagnostic value of transesophogeous echocardiography(TEE)for detection of left atrial thrombus in patients with rheumatic mitral valve disease.nethods Eighty-two patients with rheumatic mitral valve disease were enrolled.No anticoagulation treatment were administrated before TEE.Results Of 82 patients,29 patients(35%)had left atrial thrombus:11 in left atrial chamber,14 in left atrial appendege,and 4 in both left atrial body and left atrial appendege.16 patients had left atrial spontaneous echo contrast(SEC).10 of them had only SEC.6 had both SEC and left atrial thrombus.In 22 subgroup patients with lone mitral stenosis and atrial fibrilation,10 patients had left atrial tllrombus,8 patients had SEC.However,in 3 subgroup patients with mitral valve stenosis and regurgitation,only 1 patient had SEC.No left atrial thrombus was detected by transthoracic echocardiography.Conclusion Left atrial thrombus and SEC are common complications in patients with rheumatic mitral valve stenosis.especially with atrial fibrilation.TEE is a sensitive and specific method for the detection of left atrial thmmbus,especially in left atrial appendage.Accordingly,TEE should be routinely performed in patients with rheumatic mitral valve stenosis and atrial fibrilation,especially for the candidates of interventional or electral defibrilation therapies.
