目的应用超声心动图探讨感染性心内膜炎心脏赘生物形态学特征与并发症之间的关系.方法经胸超声心动图观测心脏赘生物的形态大小、回声强度、活动度、分布范围及瓣膜反流程度,结合临床资料,影像学检查如CT或MRI等,追踪随访感染性心内膜炎患者并发症情况.结果随着赘生物大小、活动度、范围分级级别及瓣膜反流程度的增加,其并发症发生率也随之增加.而赘生物的回声强度与感染性心内膜炎并发症无明显相关性.结论赘生物的活动度、范围、大小和瓣膜反流均与并发症呈显著的相关,它们均是感染性心内膜炎并发症的独立预测因素.经胸超声心动图对感染性心内膜炎并发症的发生有预测价值,并对治疗决策、预后判断有重要的临床意义.

Objective To study the relationship between excrescent morphologic features and complication of infective endocarditis(IE) by echocardiography.Methods The shape,size,consistency,mobility,distribution of vegetation and degree of valve regurgitation were observed by transthoracic echocardiography(TEE),the complications were investigated with clinical data,radiological examination,such as CT or MRI,and follow-up IE patients.Results With the increasing of vegetations in the size,mobility,extent classificatory grade and valve regurgitant degree,the incidence of IE complications also rised.There was no significant correlation between IE complications and the echo intensity of the vegetation.Conclusions The activity,extent,size of vegetations and valvular regurgitation show closely correlation with IE complications.They are independent predictors of IE complications.TEE shows great value in predicting the occurrence of complications,and it has important clinical significance in prognosis and therapeutic decision-making.
