title: Successful thrombectomy for coronary embolism likely due to floating aortic plaque in ascending aorta.
abstract: A 70-year-old man with chest pain underwent coronary intervention for acute myocardial infarction. We immediately performed coronary thrombectomy with aspiration catheter and collected solid material as a result. After aspiration, we achieved thrombolysis in myocardial infarction trial (TIMI)-flow grade 3 without stenosis. Transesophageal echocardiography showed no intracardiac thrombus but pronounced mobile aortic plaque in ascending aorta. Transthoracic echocardiography showed moderate aortic regurgitation. A histological examination of retrieved material revealed severe calcified atherosclerotic plaque without thrombotic components. Thereby, coronary embolism in this case may have been caused by embolism of flaked aortic plaque, which was possibly carried by aortic regurgitation flow.
