Overview
LV aneurysms could be classified based on their components or the location. The main classification method is based on their components which is classified as true or false (pseudo).
Classification
Based on the wall nature and it's 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.
According to the location of aneurysm they may be divided to anterolateral (apical) or posterior.[1]
