How long after myocardial infarction does a ventricular aneurysm develop?
A ventricular aneurysm develops in the setting of remote prior myocardial infarction. Areas of the heart muscle that have undergone infarction ultimately become thin and fibrotic; these weak areas of myocardium can balloon out over time because of chronic exposure to systemic blood pressure. True ventricular aneurysms usually have a wide mouth, are most commonly anteriorly located, and may undergo mural calcification, resulting in a characteristic curvilinear density on chest radiographs
