Resolution of left ventricular thrombus after myocardial infarction by anticoagulant therapy: Report of a case

A 57-year-old man experienced acute anterior myocardial infarction and had been admitted to another hospital 1.5 months earlier. He visited our outpat ient department because of experiencing mild dyspnea on exertion. Two-dimen sional echocardiography revealed left ventricular systolic dysfunction, lef t ventricular apical aneurysm formation, as well as left ventricular thromb us at the low septal apical region. The thrombus decreased in size and then resolved completely after anticoagulant therapy. No evidence of systemic e mbolism was seen during the course of anticoagulant therapy. In conclusion, anticoagulant therapy is effective for the resolution of left ventricular thrombus after myocardial infarction.
