摘　　要：目的评价经胸超声心动图诊断感染性心内膜炎的价值。方法回顾性分析114例感染性心内膜炎患者的经胸超声心动图特征及临床资料,观察心脏瓣膜形态结构、活动及对合功能,寻找赘生物,观察瓣周结构及有无基础心脏病变。结果 114例患者中,104例以发热为首发症状,69例有基础心脏病,5例有全身性疾病。血培养阳性35例。超声示累及二尖瓣46例、主动脉瓣48例、三尖瓣17例、肺动脉瓣1例、人工瓣膜9例,其中多瓣膜受累7例;存在严重并发症19例。59例接受手术患者中,56例检出赘生物,术前超声诊断正确,诊断正确率为94.92%(56/59)。结论经胸超声心动图可准确诊断感染性心内膜炎。Objective To assess the clinic value of transthoracic echocardiography in diagnosis of infective endocarditis.Methods Transthoracic echocardiography features and clinic data of 114 patients with infective endocarditis were analyzed retrospectively.The form,activity and coaptation of cardiac valve were observed.The vegetation was found,and the surrounding structure of valve and fundamental heart disease were studied.Results Among 114 patients,the primary symptom presented as fever in 104 patiens.Fundamental heart disease was found in 69 patients;and systemic disease was found in 5 patients.Blood culture was positive in 35 patients.Mitral valve was involved in 46 patients.Aortic valve was involved in 48 patients.Tricuspid valve was involved in 17 patients.Pulmonary valve was involved in 1 patient.Prosthetic valve was infected in 9 patients.Multi-valves were infected in 7 patients.There were serious complications in 19 patients.Ultrasound showed vegetation in 56 of 59 patients underwent surgery.And the diagnostic accuracy rate was 94.92%（56/59）.Conclusion Transthoracic echocardiography can be used to accurately diagnose infective endocarditis.
