We present a patient with a large, left atrial ball valve thrombus that was intermittently obstructing a bioprosthetic mitral valve. The diagnosis was confirmed by transesophageal two-dimensional echocardiogram. The transthoracic study initially had failed to demonstrate the true ball valve nature of the thrombus and instead, suggested two separate mass lesions, one in the left atrium and one in the bioprosthetic mitral valve.
我们报告一例患有巨大左心房球瓣血栓的患者，该血栓间歇性阻塞生物瓣二尖瓣。经食管二维超声心动图确诊。经胸检查最初未能显示血栓的真正球瓣性质，反而提示有两个独立的肿块，一个位于左心房，一个位于生物瓣二尖瓣。
