Right-sided infective endocarditis (RSIE) is a relatively uncommon condition which is difficult to distinguish from thrombus, particularly when the site of infection or the patient's symptoms are atypical. There have been few reports exploring the differential diagnostic and analytical features between RSIE and thrombus.
Here, we presented two cases of RSIE-one involving the tricuspid valve and the other affecting the pulmonary artery. Notably, the second case was initially misdiagnosed as thrombus based on the findings of by computed tomography angiography(CTA).
Vegetation and thrombus can be distinguished according to the nature of the mass, its attachment location, and the clinical manifestation. Echocardiography can observe both the location and size of the mass, and the dynamic changes in cardiac hemodynamics and cardiac morphology, thereby facilitating an effective distinction between vegetation and thrombus.
右侧感染性心内膜炎（RSIE）是一种相对少见的疾病，与血栓难以区分，特别是在感染部位或患者症状不典型时。关于 RSIE 和血栓之间的鉴别诊断和分析特征，鲜有报道。
在此，我们报告了两例 RSIE 病例，一例累及三尖瓣，另一例累及肺动脉。值得注意的是，第二例最初根据计算机断层血管造影（CTA）的结果误诊为血栓。
可根据肿块的性质、附着部位和临床表现来区分赘生物和血栓。超声心动图可以观察到肿块的位置和大小，以及心脏血流动力学和心脏形态的动态变化，从而有效地区分赘生物和血栓。
