An elderly patient with severe aortic stenosis and myocardial infarction with a huge mobile thrombus as complication in the left ventricle

An 86-year-old woman was admitted for emergency treatment of increasing dyspnea. Transthoracic echocardiography revealed decreased left ventricular systolic function with dyskinesis at the apex, and severe aortic stenosis. The apex of the left ventricle showed a huge mobile thrombus. Coronary angiography revealed total occlusion at the middle portion of the left anterior descending coronary artery. Emergency operation was successful, and a partially calcified thrombus was observed at the site of the old myocardial infarction area. In this case, myocardial infarction and elevated intraventricular pressure due to aortic stenosis likely contributed to the wall motion abnormality and thrombus formation.
