Abstract

Introduction: Pseudoaneurysm may occur as a rare complication of myocardial infarction (MI) when a hemorrhagic process is covered by adherence of the visceral or parietal pericardium or of both, preventing the formation of cardiac tamponade. Pseudoaneurysm is prone to rupture because they are not easy to diagnose.

Case presentation: Here, we report three cases of left ventricular pseudo-aneurysm (LVP) that all were related to MI. Two patients were managed conservatively, one of them was lost to follow-up, and the other one expired one month later. One patient underwent surgery, but he expired during post-operation period.

Conclusions: High mortality rate of LVP emphasizes the importance of looking for it in cardiac evaluation of patients with history of MI. Due to available non-invasive modalities, the ability to differentiate LVP from other cardiac pathologies is improving. Still, the most recommended management of LVP is early surgery.
