Summary
Aortopulmonary fistula is a rare complication following arterial switch operation in infants with transposition of the great arteries. This case highlights a successful surgical repair in a 3-month-old boy, improving outcomes.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Aortopulmonary fistulas are known complications in adults with aortic dissection and atherosclerosis.
- Arterial switch operation (ASO) is a standard surgical procedure for transposition of the great arteries (TGA).
- This study addresses a previously unreported complication of ASO in pediatric patients.
Observation:
- A 3-month-old boy, post-neonatal ASO for TGA, developed severe congestive heart failure.
- The patient had undergone balloon dilation for supravalvular pulmonary stenosis.
- An undiagnosed aortopulmonary fistula between the ascending aorta and main pulmonary artery was identified.
Findings:
- The aortopulmonary fistula was a previously unreported complication after arterial switch operation in a patient with transposition of the great arteries.
- The fistula was successfully surgically repaired.
- The patient recovered uneventfully after the repair.
Implications:
- This case expands the spectrum of known complications after arterial switch operation.
- Early diagnosis and surgical intervention are crucial for managing aortopulmonary fistulas in pediatric cardiac surgery patients.
- Highlights the importance of considering rare complications in postoperative management of complex congenital heart defects.
