An operation for anomalous origin of left coronary artery

Area of Science:

• Pediatric Cardiology
• Congenital Heart Defects
• Surgical Innovation

Background:

• Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect.
• This condition typically leads to myocardial ischemia and heart failure in infants and young children.
• Early diagnosis and surgical intervention are crucial for survival and optimal outcomes.

Observation:

• A 4-year-old child presented with clinical, hemodynamic, and angiographic features consistent with ALCAPA.
• The anomaly involved the left coronary artery originating from the pulmonary artery instead of the aorta.
• This anatomical variation compromises coronary blood flow and myocardial perfusion.

Findings:

• A novel surgical technique was employed for correction.
• This involved creating an aortopulmonary fistula and inserting a pericardial baffle within the pulmonary artery.
• The baffle successfully redirected flow from the fistula to the left coronary ostium.

Implications:

• The surgical approach resulted in successful correction of the ALCAPA.
• The child demonstrated satisfactory clinical progress 17 months post-operation.
• This case highlights a potentially effective surgical strategy for ALCAPA, improving pediatric cardiac surgical options.
