Abstract：Objective To explore the echocardiography manifestation of space-occupying lesions in left atrium and diagnostic value of echocardiography.Methods 66 cases of patients with ultrasound diagnosis of space-occupying lesions in left atrium unergone surgerywere followed.Results In the study of 66 cases of spaceoccupying lesions in left atrium,there were 27 cases of thrombus,20 patients with mitral valve vegetations and left atrial,15 cases of left atrial myxoma,1 paraganglioma.Left atrium of primary(1 case) and metastatic tumor(2case).Many typical acoustic image characteristics were as follows:myxoma,were attached to the interatrial septum patent foramen edge and mobility.Thrombosis has no active,at various stages of the formation and treatment performance was different.Left atrial neoplasm characterized by mitral valve or adhered to the endocardial block echo,size,shape was irregular,Larger vegetations was hard to identify with cardiac tumors,need to be combined with clinical manifestations and other auxiliary examination to diagnose.Left atrium malignant tumor was no active,and endocardial boundary was not clear,with a small amount of pericardial effusion,CDFI:a little signal can be seen in the block.Heart paraganglioma was located in the left atrium or paraganglia aorta.Conclusion Echocardiography was the detection and evaluation tool of choice for space-occupying lesions in the left atrium,can accurately describe the lesion site,size,number shape,mobility,around the relationship between organization structure and hemodynamic changes.
