目的分析超声心动图对感染性心内膜炎(IE)的诊断价值。方法选取内蒙古医科大学附属医院2015年3月—2016年3月收治的IE患者89例,均进行超声心动图检测,观察瓣膜受累情况、赘生物附着部位并测量其大小。结果血培养阳性患者30例(33.7%),其中革兰阴性杆菌9例,革兰阳性球菌21例。经超声心动图检查发现心脏瓣膜赘生物形成患者85例(95.5%),其中主动脉瓣30例、左房室瓣21例、主动脉瓣和左房室瓣13例、右房室瓣11例、肺动脉瓣10例;赘生物直径<10 mm者45例、11~15 mm者33例、16~20 mm者5例、>21 mm者2例。结论超声心动图检查能能快速发现并准确定位IE患者心脏瓣膜赘生物,诊断价值良好。
Objective To analyze the diagnostic value of echocardiography in infective endocarditis (IE). Methods 89 cases of IE patients who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from March 2015 to March 2016 were examined by echocardiography. The valvular involvement, the attachment site of neoplasm and the size of the neoplasm were observed. Results There were 30 patients (33.7%) positive for blood culture, including 9 Gram-negative bacilli and 21 Gram-positive cocci. 85 cases (95.5%) were found by echocardiography, including 30 cases of aortic valve, 21 cases of left atrioventricular valve, 13 cases of aortic valve and left atrioventricular valve and 11 cases of right atrioventricular valve , 10 cases of pulmonary valve; 45 cases of vegetation diameter <10 mm, 11 to 15 mm in 33 cases, 16 to 20 mm in 5 cases,> 21 mm in 2 cases. Conclusion Echocardiography can quickly find and accurately locate heart valve neoplasms in patients with IE, and its diagnostic value is good.
