Single coronary artery arising anomalously from the pulmonary trunk

|April 1, 1983
Summary
A rare congenital heart defect, anomalous origin of the coronary artery from the pulmonary artery, caused sudden infant death. This condition led to myocardial infarction due to inadequate coronary blood flow.
Area of Science:
- Cardiovascular Pathology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Sudden infant death syndrome (SIDS) remains a significant concern in neonatology.
- Congenital heart anomalies are a leading cause of non-sudden infant death.
- Understanding rare coronary artery anomalies is crucial for diagnosis and prevention.
Observation:
- A case study of a 10-day-old infant presenting with sudden, unexplained death.
- Autopsy revealed significant pathological findings in the cardiac system.
- The infant had no prior history of illness or distress.
Findings:
- Myocardial infarction (heart attack) was identified as a primary finding.
- A single coronary artery was observed, originating anomalously from the pulmonary artery.
- This anomalous vessel was the sole source of blood supply to the coronary arteries.
Implications:
- This case highlights the critical importance of recognizing rare coronary artery anomalies in pediatric sudden death investigations.
- Early diagnosis and potential surgical intervention for anomalous coronary arteries could be life-saving.
- Further research into the embryology and clinical presentation of such anomalies is warranted.
