A 4-week-old infant experienced heart failure and myocardial infarction due to an accessory atrioventricular pathway. This congenital heart condition can mimic other cardiac issues in infants.

Area of Science:

  • Pediatric Cardiology
  • Electrophysiology
  • Congenital Heart Disease

Background:

  • Congestive heart failure in infants can stem from various underlying cardiac anomalies.
  • Myocardial infarction is rare in neonates and requires thorough etiological investigation.

Observation:

  • A 4-week-old female infant presented with symptoms of congestive heart failure.
  • Electrocardiography indicated an anterolateral myocardial infarction pattern.
  • Cardiac catheterization revealed normal coronary arteries and moderate mitral regurgitation.

Findings:

  • Electrophysiology study identified an accessory atrioventricular conduction pathway.
  • This pathway is a likely cause of the infant's cardiac presentation.

Implications:

  • Accessory pathways should be considered in the differential diagnosis of infant myocardial infarction and heart failure.
  • Early diagnosis and management of accessory pathways are crucial for preventing adverse cardiac events in neonates.
