	LV aneurysm	LV pseudoaneurysm
Incidence	8 à 15%/MI	Rare
Physiopathology	Expansion of the infarcted segments	Myocardial rupture in the pericardium
Locations	Anterior and apex	Posterior and lateral

Treatment	Principally medical	Surgery
Risque chirurgical	Uncertain	Lower than medical treatment
TTE diagnostic accuracy	High	Low
Reference imaging	TTE±ventriculography, MRI +++ and cardiac CT scan +++.	Ventriculography, MRI+++, cardiac CT scan+++.
Morphology:
1)Nack	Large	Narrow
2)Wall	Myocardium + pericardium±thrombus	Pericardium±thrombus.
