Massive Left Ventricular Aneurysm After Inferior Infarction

True ventricular aneurysm is a rare complication of myocardial infarction. After a 53-year-old man presented late with an inferior ST-segment elevation myocardial infarction, he was found to have a massive posterobasal left ventricular aneurysm. Cardiac magnetic resonance imaging volumetric analysis highlighted the hemodynamic significance of the aneurysm. As the result of persistent symptomatic heart failure, the patient underwent surgical resection of the aneurysm and placement of a pericardial patch with excellent results at follow-up.
