INTRODUCTION:One of the purposes of echocardiography is to determine the nature of a space-occupying lesion. The conventional transthoracic echocardiogram (TTE) is the preferred method for the diagnosis of cardiac space-occupying lesions as it can reveal the baseline information. For patients with poor conditions, however, TTE cannot clearly display the boundary, it has a limited role in determining the nature of the lesions.PATIENT CONCERNS:A 47-year-old woman presented with intermittent fever for 7 days and chest distress/shortness of breath for 5 days.DIAGNOSIS:In our current case, we inferred the nature of space-occupying lesions in the left atrium more accurately using transesophageal echocardiography (TEE) than TTE, which may offer diagnostic evidence for surgical treatment.INTERVENTIONS:The patient underwent surgical resection of the left atrial tumor and reconstruction of the left atrial wall. However, the patient's posterior lobe of the mitral valve was infiltrated by tumor, which was difficult to completely remove.OUTCOMES:Echocardiography was performed 3 months after surgery and the tumor recurred in the posterior lobe of the mitral valve. Although almost all tumors have been removed by surgery, the average survival time is often less than 1 year, as it is difficult to completely remove and easy to relapse with poor prognosis.CONCLUSION:Transesophageal echocardiography (TEE) plays a relatively more important role in the determination and differential diagnosis of cardiac space-occupying lesions.

Objective To investigate the hemodynamic changes before and after Revivent surgery in patients with left ventricular apical aneurysm by cardiac magnetic resonance imaging ( CM R ) and echocardiography . Methods Twenty‐two cases with left ventricular apical aneurysm were examined by two‐dimensional and three‐dimensional transthoracic echocardiography 1 week before operation ,1 month and 12 months after operation ,by CM R 1 week before operation and 12 months after operation .Left ventricular end‐diastolic volume( LVEDV ) ,left ventricular end‐systolic volume ( LVESV ) ,left ventricular end‐diastolic diameter ( LVEDd ) , left ventricular end‐systolic diameter ( LVESd ) , left ventricular ejection fraction ( LVEF) ,stroke volume ( SV ) ,stroke output index ( SVI) ,cardiac output ( CO ) and cardiac output index ( CI) were quantitatively measured and statistical analysis were performed . Results T here were significant differences between preoperation and 1 month after operation for the measurements of LVEDV ,LVESV , LVEDd and LVEF by both CM R and echocardiography ( all P ＜ 0 .05 ) . Compared with preoperation , LVESd decreased significantly 12 months after operation ( P ＜0 .01) . However ,there were no significant differences between preoperation and 1 or 12 months after operation for the measurements of SV ,SVI ,CO and CI ( all P ＞ 0 .05 ) . T he consistency between CM R and echocardiography measurements was good . Conclusions Revivent surgery provides an effective and feasible treatment for patients with left ventricular apical ventricular aneurysm . T he dual‐modality imaging with CM R and echocardiography are reliable technical means to evaluate the changes of left ventricular heamodynamiscs during the perioperative period of Revivent

Objective To evaluate the changes of left ventricular hemodynamics and systolic function in patients with apical aneurysm after percutaneous ventricular restoration ( PVR) by echocardiography . Methods Fifty patients with apical aneurysm were divided into PVR group ( 25 cases) and conservative treatment group ( control group ,25 cases ) . Two-dimensional transthoracic echocardiography ( 2D-TTE ) combined with real-time three-dimensional transesophageal echocardiography( RT-3DTEE) were applied for all the subjects in PVR group on preoperative ,one week after operaction ,three months after operaction and in control group on initial stage of prevent ventricular remodeling therapy ,one week after therapy ,three months after therapy to obtain left ventricular end-diastolic diameter( LVEDD) ,left ventricular end-systolic diameter( LVSDD) ,left ventricular end-diastolic volume( EDV ) ,end-systolic volume( ESV ) ,left ventricular ejection fraction( LVEF) ,left ventricular fractional shortening ( LVFS ) ,body surface area ( BSA ) ,stroke volume( SV) ,stroke volume index ( SVI) ,cardiac output ( CO ) ,cardiac output index ( CI) . Results There were significant differences in all parameters( P < 0 .05) especially in LVEF and SVI( P < 0 .01) between PVR group and control group in the following three months after operaction ,while there was no significant difference of the following one week after operaction( P > 0 .05) .Compared with preoperative ,there was no difference in all parameters in the following one week after operaction ( P > 0 .05) ,there was significant increase in SV and significant reduce in LVEDD and EDV ( P < 0 .01) between preoperative and in the following three months after operaction ,while there was no significant difference between preoperative and in the following one week after operaction ( P > 0 .05 ) .For the control group there was no significant difference between initial stage of prevevt ventricular remodeling therapy and in the following one week or three months after operaction .Conclusions PVR has a definite effect on left ventricular hemodynamics and systolic function in patients with apical aneurysm in the short term ,while 2D-TTE and RT-3DTEE provides a reliable basis for clinical to evaluate the effect of the PVR .
