Key result
A case of left ventricular contained rupture mimicking a pseudoaneurysm on echocardiography was definitively diagnosed as a true aneurysm during surgical intervention.

Echocardiography may misdiagnose a true left ventricular aneurysm as a pseudoaneurysm following acute myocardial infarction.

Echocardiography risks misclassifying true LV aneurysm as pseudoaneurysm post-MI; this case leaves open the need for confirmatory imaging or surgery.
Acute myocardial infarction leading to left ventricular wall rupture is a very lethal complication with the risk of sudden cardiac death. Such contained rupture presents as aneurysmal dilatation of ventricular wall on echocardiography. A false aneurysm is bound by the pericardium without any myocardial tissue and true aneurysm is a bulging of scarred myocardium. Pseudoaneurysm with contained rupture sealed by pericardium needs early surgical intervention. Here, the authors present similar case mimicking as pseudoaneurysm on echocardiography, but it was found out to be true aneurysm as surgical finding.

Raut et al. (2017) conducted a case report in Left ventricular contained rupture following acute myocardial infarction (n=1). Surgical intervention was evaluated. A case of left ventricular contained rupture mimicking a pseudoaneurysm on echocardiography was definitively diagnosed as a true aneurysm during surgical intervention.
