Clinical Value of Ultrasound in Diagnosing Infectious Endocarditis

目的 分析超声诊断感染性心内膜炎的临床价值。方法 总结手术证实的感染性心内膜炎术前超声资料与术中对比。结果 超声对赘生物附着部位、大小、数量及有无新的血流动力学改变的判断与术中一致 ,且能发现有无心脏基础病变及受损瓣膜有无并发症。结论 超声对赘生物的检出有相当高的敏感性及特异性 。

Objective To analyse the clinical value of ultrasound in diagnosing infectious endocarditis.Methods We summarized the ultrasonic features in patients with infectious endocarditis before surgery and later on confirmed by operation and compared the ultrasonic features with that of intraoperation.Results The ultrasounic judgement of vegetation attached portion,its size ,numbers and with or without hemodynamic changes was correspondent to that of intraoperation.Farther more,ultrasound could help to find out whether there were basal lesions and complications of impaired valves.Conclusions Ultrasound has high sensitivity and specificity for detecting vegetations and can provide valuable informations for determing the prognosis and complications of infectious endocarditis.
