HEART ANEURYSM

Ventricular aneurysm (on the right) and healthy heart (on the left).
A ventricular aneurysm, also named cardiac aneurysm, is a localized dilation of a ventricular wall (blood bag).
The left ventricular aneurysm is mostly a late complication of the myocardial infarction (15 % of cases). A few days or weeks after the infarction, a portion of a blood vessel located in the ventricular wall dilates, in front of the necrosis scar of the infarction site. Indeed, the dead area of the myocardium does not participate anylonger to the cardiac contraction, the region located opposite must provide a more powerful work to compensate, which favours the formation of an aneurysm.
Ventricular aneurysm can cause arythmies, cardiac insufficiency resistant to treatment and embolisms, endangering life conditions.
