Large left atrial mural thrombi in the absence of mitral valve stenosis have been reported rarely in the literature. It is even rarer without history of atrial fibrillation (AF). These masses can cause systemic embolization and sudden circulatory collapse when they obstruct the mitral valve. We are presenting a case of giant, free floating ball thrombus, detected after aortic valve replacement for mixed aortic valve disease. It was found immediately before separation from cardiopulmonary bypass by transoesophageal echocardiography and was successfully removed. A ball thrombus without mitral valve disease and AF with aortic valve disease is not yet reported in the literature.
文献中鲜有报道左心房巨大壁血栓而无二尖瓣狭窄，且无房颤病史者更为罕见。这些血栓块可在阻塞二尖瓣时导致体循环栓塞和循环突然崩溃。我们报告了一例混合主动脉瓣疾病行主动脉瓣置换术后发现的巨大游离球型血栓病例。在经食管超声心动图检查发现它即将在体外循环分离前，并成功将其取出。目前尚未有文献报道主动脉瓣疾病而无二尖瓣疾病和房颤的球型血栓。
