A patient who developed thrombosis on a Björk-Shiley aortic valve prosthesis is reported. The patient presented with severe angina pectoris and the main physical findings were absence of the closing click of the prosthetic valve and the presence of systolic and diastolic aortic murmurs. Echocardiography showed early closure of the mitral valve and depressed left ventricular function. An emergency operation was performed and the clot was removed. The patient's recovery was uneventful and he is well one year after surgery. Awareness of the possibility of valve thrombosis is necessary in view of the need for emergency surgical treatment. The literature on the subject is reviewed.
本文报告了一名在Björk-Shiley主动脉瓣假体上发生血栓形成的患者。该患者表现为严重心绞痛，主要体格检查发现为人工瓣膜关闭喀喇音消失，以及存在收缩期和舒张期主动脉杂音。超声心动图显示二尖瓣提前关闭和左心室功能减退。进行了急诊手术，清除了血栓。患者恢复顺利，术后一年情况良好。鉴于需要进行急诊手术治疗，认识到瓣膜血栓形成的可能性很有必要。本文对该主题的文献进行了综述。
