Recurrent systemic embolism caused by thrombosis in a stenotic bicuspid aortic valve

Thrombosis in a native aortic valve is a rare complication whichmay lead to systemic embolization. A few cases of aortic thrombosisin previously abnormal valves have been described. In this report,we describe a 42-year-old male who suffered two acute ischaemicattacks, one in the upper right limb and another in the cerebralterritory supplied by the left sylvian artery, from a thrombusthat developed in a bicuspid and stenotic aortic valve. Thediagnosis was made with transthoracic and transoesophageal echocardiography,and the patient subsequently underwent surgery. In cases ofbicuspid aortic valves, we should think of thrombosis as a possiblecomplication with its resulting risk of embolism, and assesssuch patients with transthoracic and transoesophageal echocardiography,thus enabling their early detection and treatment.
