摘　　要：目的探讨感染性心内膜炎赘生物的超声心动图特点及诊断价值。方法应用超声心动图观察心脏赘生物的形态、大小、回声、分布及其瓣膜损害情况,对30例感染性心内膜炎心脏赘生物进行诊断。结果赘生物主要附着主动脉瓣10例,其次是二尖瓣8例,同时累及主动脉瓣和二尖瓣5例,三尖瓣1例,肺动脉瓣2例,动脉导管未闭主肺动脉2例,室间隔缺损右室面2例。赘生物长径约3～27mm,呈低回声至强回声。超声心动图对心脏赘生物的位置、大小、形态及数量的判断与手术所见基本相符,超声心动图还能对心脏基础病变及继发心血管血流动力学改变进行诊断。结论超声心动图对感染性心内膜炎赘生物能进行准确定位,并能确定其大小、形态、数目及评估心脏情况,对治疗决策及预后判断有重要的意义。Objective To investigate the feature and value of echocardiography for diagnosing infective endocarditis. Methods The shape, size, echogenicity, distribution of vegetations and valvular injury of the heart were observed in 30 patients with infective endocarditis. Results The vegetations were located in the aortic valves （10 cases）, bicuspid valves （7）, aortic and mitral valves （5）, tricuspid valve （1）, pulmonary valve （2）, main pulmonary artery with patent ductus arteriosus （2）, and fight ventricle with ventricular septal defect （2）. The size of vegetation ranged from 2 to 27 mm and the echogenicity of vegetations was low to high. The location, size, shape and amount of vegetations observed on echocardiography correlated well with the operative findings. Echocardiography also demonstrated underlying heart disease and abnormal hemodynamics induced by infective endocarditis. Conclusion Echocardiography can determine the location, size, shape, amount of vegeta- tion and concomitant cardiac disease in patients with infective endocarditis. It plays an important role in treatment and prognosis.
