| Abstract: | A 73-year-old man was hospitalized for unstable angina pectoris with no history of myocardial infarction. After undergoing percutaneous coronary intervention, left ventriculography incidentally revealed a cavity in the anterior wall, and echocardiography found the cavity wall to be dyskinetic. Myocardial contrast echocardiography revealed that the wall of the cavity was surrounded by myocardial tissue with low perfusion. Furthermore, radial strain in the wall of the cavity was low. Myocardial scintigraphy showed a localized defect on the anterior wall. The patient was finally diagnosed as true aneurysm after asymptomatic and localized myocardial infarction, and has since been followed up by echocardiography in the outpatient clinic. |
