Key result
Rapidly progressing post-MI left ventricular pseudoaneurysm leads to fatal rupture before emergency surgery.
Why the study?
Left ventricular pseudoaneurysm is a rare but fatal complication of acute myocardial infarction that requires timely diagnosis and surgical intervention.
Case Report (n=1)
Timely diagnosis and corrective surgery are critical for managing rapidly progressing left ventricular pseudoaneurysms after acute myocardial infarction to prevent fatal rupture.
Rapid post-MI LVPA progression to fatal rupture before surgery warrants close surveillance; single case leaves optimal timing unresolved.
Left ventricular pseudoaneurysm (LVPA) is a rare complication of acute myocardial infarction (MI). As pseudoaneurysm is contained by the pericardium alone without involvement of myocardial tissue, LVPA are more prone to rupture and hence necessitates surgical intervention. We report a case of a 60-year-old man with acute MI due to a three-way occlusion in the coronary arteries. An emergency transthoracic echocardiogram (TTE) on the 11th day after the MI showed a small ventricular aneurysm, which was probably a late complication of the acute MI episode. A repeat TTE on the 26th day of the MI episode revealed a rapidly progressing LVPA. Emergency heart surgery was planned, but the patient died due to LVPA rupture. This case illustrates timely diagnosis and corrective surgery are key to saving patients from fatal LVPAs.

Zheng et al. (2021) conducted a case report in Left ventricular pseudoaneurysm after acute myocardial infarction (n=1). Delayed diagnosis was evaluated on Death due to LVPA rupture. A 60-year-old man with acute myocardial infarction developed a rapidly progressing left ventricular pseudoaneurysm that resulted in fatal rupture before planned emergency surgery could be performed.
