"Left ventricular pseudoaneurysm formation typically results weeks to months following myocardial infarction, and is consequent to rupture of the myocardial free wall (most frequent 3-7 days post-MI) 5,11. The cardiac rupture is contained by adherent pericardium or scar tissue."
"Chest radiographs may show left ventricular outpouching, usually located posterolaterally. The pseudo-aneurysm can calcify after many years."
"Echocardiography typically shows the pseudoaneurysm as a saccular outpouching which originates from a sharp discontinuity of the left ventricular endocardial border. Compared to true aneurysms, pseudoaneurysms have a characteristically narrow neck; the end-systolic orifice diameter to maximal aneurysmal diameter is typically < 0.5, with aliasing and bidirectional flow visualised by colour flow and spectral Doppler. The pericardial space may also demonstrate spontaneous echo contrast and echogenic thrombus 10. In the case of pseudoaneurysms post-myocardial infarction, adjacent myocardium in the affected vascular distribution will often be dyskinetic, echogenic and thin ("

"Myocardial rupture is usually rapidly fatal; however, in this scenario, it fortuitously becomes limited by a pericardial adhesion. Thus, the pseudoaneurysm wall consists only of the epicardium, pericardium and haematoma. In contrast, a left ventricular aneurysm has a wall of scarred myocardium and endocardium."
