Key result
Clinical follow-up reveals pseudoaneurysm development 18 months after lateral LV wall rupture post-MI.
Why the study?
Lateral left ventricular wall rupture is a rare but often fatal complication following acute myocardial infarction with limited pathophysiological interpretation by multimodality imaging.
Case Report (n=1)
Demonstrates the natural history and imaging follow-up of a conservatively managed left ventricular wall rupture post-AMI developing into a pseudoaneurysm.

May support extended surveillance after conservatively managed LV rupture; leaves open optimal timing and thresholds.
Lateral left ventricular wall rupture (LVWR) is a rare complication following acute myocardial infarction (AMI) less than 1%. After cardiogenic shock, LVWR constitutes the most common cause of in-hospital death in AMI patients. Around 40% of all LVWR occurred during the first 24 hours and 85% within the first week. In the present case, 76 hours following the intervention, LVWR was observed likely due to a small infarction at the lateral left ventricular wall possibly due to the marginal lesion. Our patient refused surgery and was followed clinically. Eighteen months later, real time three-dimensional echocardiography showed a pseudoaneurysm.

Avegliano et al. (2014) conducted a case report in Lateral left ventricular wall rupture following acute myocardial infarction (n=1). Clinical follow-up without surgery was evaluated on Development of pseudoaneurysm. Clinical follow-up of a patient with lateral left ventricular wall rupture following acute myocardial infarction revealed the development of a pseudoaneurysm at 18 months.
