经食道心脏超声检测风心病左房血栓的应用

The Application of Transesophagal Echocardiography in Detection of Left Thrombus in Patients with Rheumatic Heart Disease

用经食道心脏超声(TEE)检测12例风心病(RIID)及10例非风心病对照组的左房结构及左心耳功能。结果显示:RHD组左房内血栓6例(50%),其中5例血栓位于左心耳内,左房白发超声造影(SEC)10例(83%),未见对照组左房内血栓及SEC。与对照组比,RIID纽左心耳容积及周径明显扩大(均P<0.01),射血分数及周径缩短率明显减低(均P<0.01)。说明RHD患者左房血栓发生率高,且多位于左心耳,认为左心耳功能参数与左房SEC是提示左房血栓形成的重要指标。

12 Patients with rheumatic heart disease (RHD) and 10 control subjects with other heart disease were examined by transesophageal echocardiography ( TEE) to gain information on left atrium and left atrial appendage( LAA) function. The results showed,in RHD group,6(50%) of the patients had thrombi,in which 5(83%) thrombi were in LAA,and 10 Patients had the sign of left atrial spontaneous echo contrast (SEC). No above phenomena were found in the central patients. The volme and circumference of LAA was greater but the ejection fraction and circumferent Shortening fraction of LAA was lower in RHD patients than in control patients ( P< 0. 001). In conclution, patients with RHD have a high incidence of left atial thrombus which is mostly found in LAA, LAA dysfunction and left a-trial SEC are important indications of thrombosis in left atium.
