Overview

True left ventricular (LV) aneurysm must be differentiated from pseudo aneurysm and LV diverticulum.

Differential diagnosis

True LV aneurysm must be differentiated from false aneurysms.[1] [2]

True LV aneurysm False LV aneurysm
Mostly apical (anterolateral) Mostly inferoposterior
Wide mouth Narrow mouth
Wall composed of LV myocardial remnants and fibrous tissue Wall made up of parietal pericardium
Almost never ruptures Often ruptures
May contain thrombus Almost always contain thrombus

Left ventricular diverticulum is another differential diagnosis of LV aneurysm.[3][4]
