Left ventricular pseudoaneurysm post myocardial infarction

Area of Science:

• Cardiology
• Cardiac Surgery
• Emergency Medicine

Background:

• Left ventricular (LV) pseudoaneurysm is a rare but life-threatening complication following acute myocardial infarction.
• It involves a rupture of the ventricular free wall contained by pericardial layers, lacking myocardial tissue in its wall.
• Undetected pseudoaneurysms carry an extremely high mortality rate.

Observation:

• The clinical presentation of LV pseudoaneurysm is often nonspecific, posing diagnostic challenges.
• A case of LV pseudoaneurysm was diagnosed using transthoracic echocardiography.
• The patient presented with nonspecific symptoms and unfortunately passed away shortly after emergency department arrival.

Findings:

• Transthoracic echocardiography is a key diagnostic tool for identifying LV pseudoaneurysm.
• The nonspecific clinical presentation can delay diagnosis and management.
• Prompt recognition and intervention are critical for improving patient outcomes.

Implications:

• This case underscores the critical importance of considering LV pseudoaneurysm in patients with acute myocardial infarction and atypical presentations.
• Timely diagnosis via echocardiography can facilitate urgent management strategies.
• Raising awareness among clinicians about this rare but fatal complication is essential for reducing mortality.
