title: [Ball thrombus induced by hibernating myocardium in the left ventricle; report of a case].
abstract: An 80-year-old man was admitted to our hospital for examination of a ball thrombus incidentally found in the left ventricle (LV). Coronary angiogram revealed severe triple vessel disease and LV dysfunction. Although LV wall motion in the septum and the apex was akinetic, there were no signs of myocardial infarction. It was diagnosed as an acute LV ball thrombus with hibernating myocardium due to ischemia of the left anterior descending coronary artery. Emergency coronary artery bypass grafting (CABG) and excision of the thrombus were performed. Two weeks after surgery, LV function improved and the patient was discharged from the hospital without any complication. A LV ball thrombus without myocardial infarction is rare, and thought to be caused by hibernating myocardium.
