Overview
Overview
True left ventricular (LV) aneurysm must be differentiated from pseudo aneurysm and LV diverticulum.
Differential diagnosis
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]
- It is defined as an outpouching structure that contains endocardium, myocardium, and pericardium.
- It displays normal contraction and is considered to be congenital.
