What is "ventricular aneurysm"

n. a localized dilation or protrusion on the wall of the left ventricle of the heart (occurring after a myocardial infarction)

Ventricular aneurysms are one of the many complications that may occur after a heart attack. They usually arise from a patch of weakened tissue 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.

Left ventricular aneurysm can be associated with ST elevation.
