Abstract
Left ventricular free wall rupture is one of the mechanical complications of acute myocardial infarction and it may result in cardiac tamponade as well as limiting itself by forming a pseudoaneurysm. In this report, a case of left ventricular free wall rupture and pseudoaneurysm that developed during the course of posterior myocardial infarction has been presented. Left ventricular free wall rupture and pseudoaneurysm were identified by three-dimensional transthoracic echocardiography and surgically repaired at a late stage.
