Biological aortic valve thrombosis is an exceptional complication. A 64-year-old patient positive for human immunodeficiency virus presented for syncope on exertion, 2 years after an aortic bioprosthetic valve replacement and double coronary artery bypass. Transvalvular aortic mean gradient was approximately 50 mm Hg on echocardiogram and catheterization. Cardiac computed tomography scan showed a limited opening of the bioprosthesis cusps. Surgical exploration revealed thrombosis of the three cusps on the aortic side, limiting the opening of the valve. No relation could be established between the patient's human immunodeficiency virus status and valve thrombosis.
生物主动脉瓣血栓形成是一种罕见的并发症。一位 64 岁的艾滋病毒阳性患者在主动脉生物瓣置换和双冠状动脉旁路手术后 2 年因用力性晕厥就诊。超声心动图和导管检查显示跨瓣主动脉平均梯度约为 50mmHg。心脏计算机断层扫描显示生物瓣瓣叶有限开放。手术探查显示主动脉瓣三叶瓣血栓形成，限制了瓣口的开放。患者的艾滋病毒状态与瓣膜血栓形成之间没有关系。
