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。
Left atrial structure and left atrial appendage function were measured by transesophageal echocardiography (TEE) in 12 cases of rheumatic heart disease (RIID) and 10 cases of non-rheumatic heart disease control group. The results showed that in 6 cases (50%) of left atrial thrombus in RHD group, 5 cases of thrombus were located in the left atrial appendage and 10 cases (83%) of left atrial white-hair echocardiography (SEC) SEC. Compared with the control group, the volume and the diameter of atrial appendage of RIID were obviously enlarged (both P <0.01), and the ejection fraction and the shortening rate of peripheral diameter were significantly decreased (all P <0.01). Description of RHD patients with high incidence of left atrial thrombosis, and more in the left atrial appendage, left atrial appendage and left atrial septal function parameters that suggest an important indicator of left atrial thrombosis.
