Libman-Sacks endocarditis is a rare cardiac manifestation of anti-phospholipid syndromes, in which non-infectious thrombotic vegetations are found on the heart valves. Most patients are asymptomatic whereas the risk of thromboembolism is considerable. Diagnostic work-up is based on questioning and clinical examination data looking for extracardiac signs, biological data and also on imaging, and, above all, echocardiography. We report the case of a 47-year-old female patient with no known history who is admitted to hospital with paresthesia of the right hemi-body associated with dysarthria. Cerebral CT scan confirms a paraventricular ischemic stroke. The etiological work-up for stroke is negative except the transesophageal echocardiogram which reveals mitral valve vegetations. Further investigations lead to the diagnosis of Libman-Sacks endocarditis. Treatment with Coumadin is started, with a target INR of between 2 and 3, as recommended. The clinical course was favourable, with stable lesions on transoesophageal echocardiography carried out later.
利布曼-萨克斯心内膜炎是抗磷脂综合征罕见的心脏表现,其特征是在心脏瓣膜上发现非感染性血栓性赘生物。大多数患者无症状,而血栓栓塞风险相当高。诊断检查基于询问病史、寻找心外体征和生物学数据的临床检查资料,以及影像学检查,尤其是超声心动图。我们报告一例47岁女性患者,既往史不详,因右侧半身感觉异常伴构音障碍入院。脑部CT扫描证实为脑室旁缺血性中风。除经食管超声心动图显示二尖瓣赘生物外,中风的病因检查均为阴性。进一步检查确诊为利布曼-萨克斯心内膜炎。按照推荐开始使用香豆素治疗,目标国际标准化比值(INR)为2至3。临床过程良好,随后经食管超声心动图显示病变稳定。
