Definition
Cardiac aneurysm, mural aneurysm; ventricular aneurysm,
thinning, stretching, and bulging of a weakened ventricular wall,
usually as a result of myocardial infarction.
|
Radiographic Appearance
On a chest radiograph the cardiac outline appears bulging
in the region of the aneurysm, and there may be associated
compensatory hypertrophy or pulmonary oedema. Cardiac
aneurysms tend to involve the left ventricle because the blood there
is under greatest pressure.

Pathology
Ventricular aneurysm. A bulging or ballooning out of part of the
wall of one of the heart's lower chambers (ventricles), usually the
left. If the aneurysm is present in the wall between the ventricles
(the ventricular septum), it is also known as a ventricular septal
aneurysm, an interventricular aneurysm or simply a septal aneurysm.
It maybe present since birth (congenital) or may be a complication
of a heart attack or other trauma.
Atrial aneurysm. A bulging or ballooning out of part of the wall of
one of the heart's upper chambers (atria). If the aneurysm is
present in the wall between the atria (the atrial septum), it is
also known as an atrial septal aneurysm (ASA), an aneurysm of septum
primum or an aneurysm of the septum secundum. An ASA has been
associated with an increased risk of stroke and is often accompanied
by the presence of a patent foramen ovale (PFO). It is often present
since birth (congenital).

Treatment:
Surgical intervention to repair and or strengthen the weakened
portion of the heart.
