Ventricular aneurysm

aneurysms are one of the many that may occur after a heart attack. The word refers to a bulge or 'pocketing' of the wall or lining of a commonly occurring in the blood at the base of the septum, or within the aorta. In the heart, they usually arise from a patch of weakened in a ventricular wall, which swells into a bubble filled with blood. This, in turn, may block the passageways leading out of the heart, leading to severely constricted blood flow to the body. Ventricular aneurysms can be fatal. They are usually non-rupturing because they are lined by scar tissue.
