The aim of this study was to correlate the findings obtained by transesophageal echocardiography (TEE) with those obtained during surgery and histopathologic studies in patients with mitral and/or aortic infective endocarditis. Twenty eight patients were studied. In all of them clinical history, bacteriological study and TEE. In 15 cases a positive blood culture was found and in 13 the blood culture was negative. The TEE demonstrate infective aortic vegetations in 12 cases, in mitral valve in 11 and in five in both valves. The endocarditis-associated complications were found in 53% of cases and the incidence of embolic events was of 25%. TEE findings related with the presence of vegetations were confirmed in the studies of pathologic anatomy in 92.8% and at surgery in 89.2%. These data suggest that the TEE leads to a significant improvement in the diagnosis and prognosis of mitral and/or aortic infective endocarditis, because it has a high correlation with the studies of pathologic anatomy and surgery.
本研究的目的是将经食管超声心动图（TEE）检查结果与二尖瓣和/或主动脉感染性心内膜炎患者手术及组织病理学研究结果进行对比。共研究了28例患者。所有患者均进行了临床病史、细菌学检查及TEE检查。15例血培养呈阳性，13例血培养呈阴性。TEE检查显示，12例存在感染性主动脉赘生物，11例存在二尖瓣赘生物，5例两个瓣膜均有赘生物。53%的病例发现了心内膜炎相关并发症，栓塞事件发生率为25%。在病理解剖研究中，92.8%的病例证实了与赘生物存在相关的TEE检查结果，手术中这一比例为89.2%。这些数据表明，TEE显著改善了二尖瓣和/或主动脉感染性心内膜炎的诊断和预后，因为它与病理解剖和手术研究具有高度相关性。
