A mechanical prosthetic heart valve can become acutely obstructed despite anticoagulation therapy. This can be a life-threatening complication. We report the case of a 38-year-old woman who survived obstruction of her Sorin prosthetic mitral valve. She was admitted to the hospital because of severe pulmonary edema. On auscultation, mechanical valve sounds were absent. Transthoracic echocardiography showed an immobile mechanical valve. The patient suffered a cardiac arrest while being prepared for surgery, but she underwent successful mitral valve replacement after cardiopulmonary resuscitation. When patients with prosthetic mitral valves present with acute dyspnea, the possibility of an obstructed prosthetic valve must be considered in the differential diagnosis.
尽管进行了抗凝治疗，机械人工心脏瓣膜仍可能突然发生梗阻。这可能是一种危及生命的并发症。我们报告一例38岁女性患者，其索林人工二尖瓣发生梗阻但存活下来。她因严重肺水肿入院。听诊时未闻及机械瓣膜音。经胸超声心动图显示机械瓣膜活动不动。患者在准备手术时发生心脏骤停，但在心肺复苏后成功进行了二尖瓣置换术。当人工二尖瓣患者出现急性呼吸困难时，鉴别诊断中必须考虑人工瓣膜梗阻的可能性。
