A rare case of anomalous left circumflex coronary artery from the left pulmonary artery

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease
• Vascular Anatomy

Background:

• Anomalous origin of the coronary artery from the pulmonary artery (ACAP) is a rare congenital heart defect.
• Specifically, anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is often fatal in neonates due to myocardial failure.
• Early detection and intervention are crucial for managing these conditions.

Observation:

• A 46-month-old child presented with an asymptomatic cardiac murmur.
• Diagnostic evaluation revealed an anomalous origin of the left circumflex artery (LCx) arising from the left pulmonary artery.
• This specific anomaly represents a variation of ALCAPA.

Findings:

• The child's condition was successfully treated with immediate surgical re-implantation of the anomalous left circumflex coronary artery.
• The surgical outcome was favorable, indicating the feasibility of corrective procedures even in older children.

Implications:

• This case demonstrates that surgical correction of anomalous coronary artery origins from the pulmonary artery can be successful beyond the neonatal period.
• It underscores the importance of thorough cardiac evaluation for unexplained murmurs in children.
• Successful re-implantation offers a potential life-saving intervention for this rare but serious congenital heart anomaly.
