Summary
A novel surgical approach was used to treat anomalous left coronary artery from the pulmonary artery in an infant with hereditary spherocytosis. This technique successfully bypassed the blocked artery without cardiopulmonary bypass, ensuring patient safety.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Hereditary Spherocytosis
Background:
- Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect requiring surgical correction.
- Hereditary spherocytosis poses a significant risk for hemolytic anemia, complicating cardiopulmonary bypass due to potential blood-related complications.
Observation:
- A 6-week-old infant (4 kg) presented with ALCAPA.
- The patient's hereditary spherocytosis precluded standard ALCAPA repair involving cardiopulmonary bypass.
Findings:
- A successful surgical correction was achieved using off-pump techniques.
- The procedure involved ligation of the left main coronary artery and left internal mammary artery-to-left anterior descending artery bypass grafting.
- This innovative approach was performed successfully with the heart beating, avoiding cardiopulmonary bypass.
Implications:
- This case demonstrates a viable alternative surgical strategy for ALCAPA in patients with contraindications to cardiopulmonary bypass.
- The successful off-pump approach highlights the adaptability of surgical techniques in complex pediatric cardiac cases.
- This method may reduce risks associated with cardiopulmonary bypass in patients with hematologic disorders like hereditary spherocytosis.
