目的：了解超声心动图对感染性心内膜炎（ＩＥ）的诊断价值。方法：分析了４７例ＩＥ病人临床及超声心动图（ＵＣＧ）资料。结果：４７例ＩＥ病人中赘生物检出率为７０．５％；原发病以风心病为多（２１例，４４．６％），其次为先心病（１８例，占３８．１％）；诱因以上呼吸道感染为多（１４例，占２９．８％）；临床症状以发热贫血为主（２７例，占５７．４％）；血培养１６例阳性（３４％）。结论：ＵＣＧ检出赘生物对ＩＥ诊断有非常重要价值，对赘生物的大小、部位、数目，以及对判断ＩＥ的合并症和治疗均有重要意义。
Objective: To understand the diagnostic value of echocardiography in infective endocarditis (IE). Methods: Clinical and echocardiographic (UCG) data of 47 patients with IE were analyzed. Results: The detection rate of neoplasms was 70.5% in 47 cases of IE. The prevalence of rheumatic diseases was mostly in 21 cases (44.6%), followed by congenital heart disease (18 cases, 38.1%). (14 cases, accounting for 29.8%); clinical symptoms were mainly anemia (27 cases, accounting for 57.4%); and blood culture was positive in 16 cases (34%). CONCLUSION: The detection of neoplasm by UCG is very important for the diagnosis of IE. It is of great significance for the size, location, number of neoplasms, and for the complication and treatment of IE.
