A free-floating ball thrombus in the left atrium is a rare occurrence. Few patients who developed a ball thrombus after mitral valve replacement have been reported. Our patient was a 58-year-old man who had undergone mitral valve replacement in 1981. Since bleeding gastric cancer had been diagnosed anticoagulant therapy had been 4 days before admission. On admission, echocardiography revealed a large thrombus in the left appendage. First, he underwent total gastrectomy for gastric cancer. After the operation, he developed aspiration pneumonia, and was intubated. We observed that a large thrombus had moved from the left appendage to the left atrium. Emergency operation was successfull.
