Abstract
Free wall rupture of the left ventricle (LV) is a rare but life‑threatening complication of acute myocardial
infaction. Very rarely such rupture may be contained by the adhering pericardium creating a pseudoaneurysm.
This condition warrants for an emergency surgery. Left ventricular aneurysm is the discrete thinning of the
ventricular wall (<5 mm) with akinetic or dyskinetic wall motion causing an out‑pouching of the ventricle. Given
the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared
with a more benign natural history for true aneurysms, accurate diagnosis of these conditions is important.
True aneurysm, usually, calls for an elective surgery. Clinically differentiating the two conditions remains a
challenge. We report the case of a patient with LV pseudoaneurysm, initially diagnosed as true aneurysm at
our institution. We have attempted to review the existing literature and discussed the characteristic findings
of each entity.
