Myocardial infarction is the most common cause of left ventricular (LV) aneurysm formation. Less common causes include HCM, trauma, idiopathic and congenital abnormalities.


Common Causes

The most common cause of LV aneurysm is myocardial infarction. It accounts for approximately 90% of apical aneurysms.[1] Other less common causes include:[2][3][4][5][6][7]
