Abstract:
Left ventricular pseudoaneurysm is an uncommon complication after transmural myocardial infarction, occurring when a free wall rupture is contained by adhesions of the overlying pericardium preventing acute tamponade. In this report, an unusual case of a 61 year-old male with a giant apical left ventricular pseudoaneurysm after an unnoticed myocardial infarction is presented. On coronary angiogram myocardial bridging of the distal left anterior descending artery was judged to be the infarct related lesion. The echocardiographic diagnosis allowed for a timely surgical intervention which resulted in the patient's full recovery.
Insights
A rare case of a giant left ventricular pseudoaneurysm, a complication of myocardial infarction, was successfully treated. Echocardiography enabled timely surgical repair, leading to full patient recovery.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Left ventricular pseudoaneurysm (LVPA) is a rare but serious complication following transmural myocardial infarction.
- It arises from a contained free wall rupture, prevented from causing acute cardiac tamponade by pericardial adhesions.
Observation:
- A 61-year-old male presented with a giant apical LVPA.
- The patient had an unnoticed myocardial infarction, with myocardial bridging of the distal left anterior descending artery identified as the likely cause.
- Diagnosis was confirmed using echocardiography.
Findings:
- The case highlights an unusual presentation of LVPA after myocardial infarction.
- Myocardial bridging was identified as the infarct-related lesion.
- Echocardiography proved crucial for diagnosis.
Implications:
- Prompt diagnosis via echocardiography is vital for managing LVPA.
- Surgical intervention can lead to full recovery in patients with LVPA.
- This case underscores the importance of considering rare complications after myocardial infarction.
