The echocardiograms of 17 patients with proved infective endocarditis were surveyed to assess the reliability of echocardiography in this disease. Vegetations were present on 20 valves (11 aortic, 7 mitral, 2 tricuspid) at surgery or autopsy. Echocardiography correctly identified the abnormality in 11 valves. There were 8 valves with false-negative studies of which only one examination was technically inadequate. One false-positive echocardiogram was found. A negative echocardiogram does not exclude infective endocarditis. The size of the vegetation is not the only consideration in its detection echocardiographically. False-positive and false negative studies are discussed.
对17例确诊为感染性心内膜炎的患者的超声心动图进行了研究,以评估超声心动图在该病中的可靠性。手术或尸检时,20个瓣膜(11个主动脉瓣、7个二尖瓣、2个三尖瓣)上发现有赘生物。超声心动图正确识别出11个瓣膜的异常。有8个瓣膜的检查结果为假阴性,其中只有一次检查在技术上不充分。发现了一次超声心动图检查结果为假阳性。超声心动图检查结果为阴性并不能排除感染性心内膜炎。赘生物的大小不是超声心动图检测时唯一需要考虑的因素。文中讨论了假阳性和假阴性检查结果。
