It is also one of the many complications that occurs after severe heart attack "Myocardial Infractions". It usually arise from the patch of weakened tissue in a ventricular wall in which it filled with large number of bubbles filled with blood. This lead to the block of passageways leading out of the heart and leading to severely constricted blood flow to the body. It can be fatal and they are non-rupturing because they are lined by scar tissue. The heart wall is mainly muscle. It has two ventricles, the right and left ventricles, which pump blood to and from the lungs, and to the body.
When part of the heart muscle dies, pumping power from that part of the wall is lost. After a myocardial infarction, the part of the heart wall that did not die must continue pumping blood and compensate for the dead muscle. Ventricular aneurysm is one of the complications that follow a myocardial infarction. An aneurysm is the outward swelling, or ballooning, of a blood vessel at a weak spot in the wall of the blood vessel. In the case of ventricular aneurysm, the aneurysm occurs in the wall of the heart at the spot where the myocardial infarction occurred. A scar usually forms in the area of the dead muscle tissue, and may eventually calcify.
Ventricular aneurysms generally do not rupture. The left ventricle is involved in most cases of ventricular aneurysm.
Causes & Symptoms:- -
Cardiac insufficiency, in which not enough blood is being pump to the body. -It mainly seen immediately after myocardial infraction. -Recurrent ventricular, recurrent irregular heartbeats (arrhythmias) and low cardiac output. -Blood clots may form on the inside wall of the aneurysm and produce systematic blood clots that get stuck in blood vessel(embolisms) which could lead to stroke or ischemic leg.
