Abstract：
A 54-year-old woman with a mechanical mitral valve replacement presented with recurrent admissions for pneumonia and pulmonary edema. Multimodality imaging revealed mobile masses on the prosthesis and discrepant point of care and inpatient international normalized ratio levels owing to antiphospholipid antibody cross-reactivity on the outpatient assay. The prosthetic valve thromboses resolved with therapeutic anticoagulation. (Level of Difficulty: Beginner.).
摘要：
一名54岁接受机械二尖瓣置换术的妇女因肺炎和肺水肿反复入院。多模态成像显示，由于门诊检测中的抗磷脂抗体交叉反应性，假体上的移动质量以及护理点和住院患者国际标准化比率水平的差异。人工瓣膜血栓通过治疗性抗凝解决。（难度等级：初学者。).
