LEFT VENTRICULAR ANEURYSM

Abstract

Post infarction true ventricular aneurysm
may be defined as a localized area of dyskinesia
with regional systolic expansion. The definition
from surgical observation leads to the following
criteria: the presence of a scar like deformity of
the ventricular wall, the presence of akinesia or
dyskinesia, myocardial thinning or scar formation
and the loss of trabecular pattern of the
endocardium.
It has become common clinical practice
to classify ventricular aneurysms with an external
bulge as true or false. The wall of the true
aneurysm is derived from the myocardium itself
whereas the wall of the false aneurysm
(pseudoaneurysm) is derived from the pericardium 2.
The reported incidence of left ventricular
aneurysm (LVA) ranges from 35% to 40%. This
wide range is partly a reflection of a lack of
generally applied definitions 2'3. Aneurysm
formation probably occurs within 3 months after
the acute myocardial infarction (AMI) but has
been reported to be two weeks to two years after
AMI3. Factors such as a large transmural AMI and
first AMI have been associated with LVA 4. The
greatest risk of aneurysm follows infarction in the
area supplied by the left anterior descending
artery
