# A Leaky False Pouch: Left Ventricle Pseudoaneurysm with Active Hemopericardium Detected on Cardiac Computed Tomography Angiography

## TL;DR

A rare heart condition following a heart attack was detected using a specialized CT scan, showing the importance of early diagnosis for life-threatening complications.

## Contribution

Demonstrates the utility of cardiac computed tomography angiography in diagnosing a rare post-heart attack complication with active bleeding.

## Key findings

- Cardiac computed tomography angiography identified a left ventricle pseudoaneurysm with active hemopericardium.
- Attenuation measurement on CCTA confirmed active extravasation into the pericardium.
- Early detection using advanced imaging improved clinical management of a rare post-MI complication.

## Abstract

Pseudoaneurysm is a rare but fatal complication of myocardial infarction (MI). With the advances in cardiovascular disease detection and treatments, fatal structural complications post-MI are now rare. When they occur, advanced diagnostic modalities can be used for early diagnosis, aiding surgical planning, and improving prognosis. In our case, post-MI left ventricle pseudoaneurysm complicated by hemopericardium was diagnosed using cardiac computed tomography angiography (CCTA). Use of attenuation measurement on CCTA helped diagnose active extravasation into the hemopericardium. This case highlights the high index of suspicion needed for rare but fatal complications post-MI and the utility of CCTA in their management.
