Overview
The main classification method is based on the components of the wall of the aneurysm, and it classifies LV aneurysms into true and false (pseudo) aneurysms.
Classification
Components
Based on the nature of the wall of the aneurysm and its components, left ventricular aneurysms are classified as true or false aneurysms.[1]

True Left Ventricular Aneurysm
A true left ventricular aneurysm has an aneurysmal sac which contains the endocardium, epicardium, and thinned fibrous tissue (scar) that is a remnant of the left ventricular muscle.
False Left Ventricular Aneurysm or Pseudoaneurysm
Unlike a true aneurysm, which contains some myocardial elements in its wall, the walls of a false aneurysm are composed of organized hematoma and pericardium and lack any element of the original myocardial wall.
Location
Left ventricular aneurysm may also be classified by location as anterolateral (apical) or posterior.[1]
