Airway Improvement with Medium-Term Compression Duration after Right Pulmonary Artery Anterior Translocation

Area of Science:

• Pediatric Cardiology
• Thoracic Surgery
• Congenital Heart Disease

Background:

• Left main bronchus compression is a rare complication in patients with cardiac anomalies.
• This condition can lead to recurrent respiratory issues, such as pneumonia and desaturation.
• Congenital heart defects like atrial septal defect (ASD) with a right aortic arch can predispose to airway compression.

Observation:

• A 19-month-old female presented with recurrent pneumonia and desaturation.
• The patient had a history of atrial septal defect (ASD) and a right aortic arch.
• Imaging revealed compression of the left main bronchus by the enlarged right pulmonary artery (RPA) and descending thoracic aorta, present for 14 months.

Findings:

• Surgical intervention involving ASD closure and anterior translocation of the RPA was performed via sternotomy.
• The surgical approach successfully relieved the extrinsic compression of the left main bronchus.
• Symptomatic improvement was noted despite the medium-term duration of bronchial compression.

Implications:

• Surgical correction of congenital heart defects can effectively resolve associated airway compression syndromes.
• Early diagnosis and intervention are crucial for managing pediatric patients with cardiac-related bronchopulmonary complications.
• This case highlights the importance of considering vascular anomalies as a cause of persistent respiratory symptoms in infants.
