Left ventricular aneurysm differential diagnosis
Introduction
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.
