感染性心内膜炎的超声心动图诊断价值分析

An analysis of the diagnostic value of ultrasonic cardiogram in infective endocarditis

目的分析37例感染性心内膜炎赘生物的超声心动图诊断价值。方法应用超声心动图(包括食道超声)观察心脏瓣膜赘生物形态、大小、回声、颁布及其瓣膜功能。结果超声心动图发现附着的部位以主动脉瓣组最多13例,其次为二尖瓣组12例,能对形成赘生物的大小(最大1.0 cm×2.1 cm,最小0.2 cm×0.2 cm)、形态、活动方式或瓣膜穿孔的形成、腱索断裂等特征以及相应出现的血流动力学变化进行评估,并能准确测量心脏收缩舒张功能。结论超声心动图对感染性心内膜炎赘生物的诊断定位、治疗的决策及预后判断均有重要意义。

Objective To analyze the diagnostic value of ultrasonic cardiogram in vegetation of 37 cases of infective endocarditis. Methods Ultrasonic cardiogram （including transesophageal echocardiography） was applied to observe the form, size, echo, distribution and valvular functions of valvular vegetation. Results The number of attached sites was the most in aortic valve group of 13 cases by ultrasonic cardiogram, and the second most was in mitral valve of 12 cas-es. The size （the biggest 1.0 cmí2.1 cm and the smallest 0.2 cmí0.2 cm）, form and the mode of activity of the vegeta-tion, or characteristics of perforation of cardiac valve and rupture of chordae tendinca as well as haemodynamic changes were evaluated, and systolic and diastolic functions were measured. Conclusion Ultrasonic cardiogram is of great signif-icance in the diagnosis and location of vegetation of infective endocarditis, treatment decision-making and prognosis judgment.
