Mechanical valve thrombosis is a severe complication of valve replacement associated with significant patient morbidity and mortality. The main factors that predispose patients to thrombus formation include endothelial injury or dysfunction, hypercoagulability, and hemodynamic changes. Other contributing factors include level of anticoagulation, tricuspid valve replacement, bacteremia, and certain patient comorbidities. Early diagnosis of thrombus could prevent adverse patient outcomes. We describe the use of transesophageal echocardiography in the diagnosis of acute thrombus in a patient with a recently replaced single atrioventricular valve.
机械瓣膜血栓形成是瓣膜置换术后的一种严重并发症，与患者的高发病率和死亡率相关。使患者易形成血栓的主要因素包括内皮损伤或功能障碍、高凝状态和血流动力学改变。其他促成因素包括抗凝水平、三尖瓣置换、菌血症和某些患者合并症。血栓的早期诊断可预防患者出现不良后果。我们描述了经食管超声心动图在诊断一名近期置换单房室瓣膜患者的急性血栓中的应用。
