左、右心感染性心内膜炎的临床及超声特征

Clinical and echocardiographic features of left or right heart endocarditis

目的探讨左、右心感染性心内膜炎的临床和超声特征。方法采用回顾性方法分析了7例右心感染性心内膜炎和11例左心感染性心内膜炎。结果与左心感染性心内膜炎相比，右心感染性心内膜炎多见于基础心脏病者（86％）、静脉吸毒者（100％）、多为金葡菌感染（80％）、多累及三尖瓣（57％）、临床表现为肺部炎症（100％）、预后良好。结论左、右心感染性心内膜炎在基础心脏病、血培养结果、临床特点以及超声心动图等方面均明显不同。彩色多普勒二维超声心动图对左、右心感染性心内膜炎的诊断具有重要价值。

Objective To understand the clinical and echocardiographic features in patients with left or right heart endocarditis. Methods 7patients with right heart endocarditis (RHIE) and 11patients with left heart endocarditis (LHIE) were retrospectively analysed. Result Compared to LHIE,RHIE usually involves patients with no basic heart diseases(86%), introvenous drug abusers (100%).Pseudomonas aeruginosa is most common isolated microorganism(80%). involved valve is usually tricuspid valve (57%), the clinical presentation is frequently dominated by pulmonary manifestations (100%) and prognosis is good. Conclusion LHIE and RHIE are significantly different in basic heart diseases, microgranisms isolated, clinical and echocardiographic features and color Doppler echocardiography is of great value in diagnosing LHIE and RHIE.
