Preseptostomy myocardial infarction in a patient with complex transposition of the great arteries

Area of Science:

• Cardiology
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Transposition of the great arteries (TGA) is a critical congenital heart defect where systemic venous return is directed to the aorta.
• This abnormal circulation predisposes patients to embolic events causing organ infarction.
• Myocardial and cerebral infarction are serious potential complications in TGA patients.

Purpose of the Study:

• To highlight the risk of infarction in patients with TGA.
• To present a case of myocardial and brain infarction in a TGA patient.
• To emphasize the importance of minimal handling of venous sites in TGA management.

Main Methods:

• Case report presentation.
• Review of clinical course and diagnostic findings.
• Discussion of potential embolic pathways in TGA.

Main Results:

• The patient experienced myocardial infarction before balloon septostomy.
• The patient later sustained a documented brain infarction despite precautions.
• These events underscore the embolic risk associated with TGA.

Conclusions:

• Systemic emboli in TGA can lead to severe organ damage, including myocardial and cerebral infarction.
• Minimal manipulation of venous access sites is crucial to mitigate embolic risk.
• Vigilance and careful management are essential for patients with TGA.
