Abstract: Left ventricular pseudoaneurysm is a rare and potentially fatal complication of myocardial infarction. We report a case of a unruptured giant left ventricular pseudoaneurysm in a 72-year-old woman possibly after a silent myocardial infarction. The patient admitted to our clinic for progressive dyspnea and anginal pain for 7 years. Echocardiography showed a giant (7x11 cm sized) pseudoaneurysm with thrombus in the internal wall. This case illustrates that a silent myocardial infarction could well be followed by pseudoaneurysm development and underlines the diagnostic value of transthoracic echocardiography.
