Mentions: First, she experienced acute myocardial infarction with the culprit lesion in the right coronary artery. Percutaneous catheter intervention for this lesion was successful, and the peak level of CPK was 1317 IU/L. However, symptoms of heart failure were worsened 26 days after admission. A 40×30 mm free-floating ball thrombus was detected in the left atrium with TTE and computed tomography (CT) (Figure 1). Because it was diagnosed shortly after myocardial infarction, nonsurgical treatment was selected. Heparin (12,000 U/day) was started along with warfarin (2 mg). The thrombus disappeared in six days after intensive anticoagulant therapy. However, she developed systemic embolization, including left cerebellar infarction, splenic infarction, and right renal infarction. We speculated that these disorders were due to embolization of the resolving thrombi in the left atrium. She recovered with only mild sequelae and she was able to leave our hospital.
