目的:探讨超声心动图在感染性心内膜炎诊断中的临床价值。方法:回顾性分析42例经手术证实的感染性心内膜炎患者的术前超声心动图资料,并与微生物学检验及术中资料进行对比。结果:超声心动图赘生物检出率(n=34,81.0%)高于血培养阳性率(n=17,40.5%),两者差异有统计学意义(P<0.01);超声心动图对赘生物的大小、数量、位置以及对心脏基础病因和心脏并发症的判断与术中所见基本一致。结论:超声心动图对感染性心内膜炎的诊断具有重要的临床价值,并可对感染性心内膜炎患者的心脏基础病因及心脏并发症提供有价值的信息。
Objective: To investigate the clinical value of echocardiography in the diagnosis of infective endocarditis. Methods: The echocardiographic data of 42 patients with infective endocarditis confirmed by surgery were retrospectively analyzed, and compared with the results of microbiological examination and intraoperative data. Results: The echocardiographic neoplasms detection rate (n = 34,81.0%) was higher than that of blood culture (n = 17,40.5%), the difference was statistically significant (P <0.01) The size, number, location of the neoplasm, and the judgment of the underlying etiology and cardiac complications of the heart are basically the same as those seen in the operation. Conclusion: Echocardiography has important clinical value in the diagnosis of infective endocarditis, and can provide valuable information on the underlying etiology and cardiac complications in patients with infective endocarditis.
