Insights
Anomalous origin of the right pulmonary artery from the ascending aorta (hemi-truncus arteriosus) is rare. This case highlights a successful palliative banding procedure for an adult patient with this congenital heart defect.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Medical Case Reports
Background:
- Anomalous origin of the right pulmonary artery from the ascending aorta, or hemi-truncus arteriosus, is a rare congenital cardiovascular malformation.
- While typically presenting in infancy, this condition can manifest in adulthood.
Observation:
- A 41-year-old female presented with a history of intermittent haemoptysis.
- Cardiac catheterisation confirmed the diagnosis of hemi-truncus arteriosus.
Findings:
- Definitive surgical correction of hemi-truncus arteriosus in adulthood carries extremely high risks.
- A palliative right pulmonary artery banding procedure was successfully performed.
Implications:
- Palliative right pulmonary artery banding offers a simple yet effective management strategy for adult hemi-truncus arteriosus.
- This approach may be a viable alternative to high-risk definitive surgery in select adult cases.
Abstract:
Anomalous origin of the right pulmonary artery from the ascending aorta, also called hemi-truncus arteriosus, is a rare congenital cardiovascular malformation. Around 95% of the reported cases with hemi-truncus arteriosus present in infancy. We describe a case of a 41-year-old female presenting with a long-standing history of intermittent haemoptysis. Cardiac catheterisation confirmed the diagnosis of hemi-truncus arteriosus. The definitive treatment of hemi-truncus arteriosus in adulthood is an extremely high-risk procedure. We decided to perform palliative right pulmonary artery banding which represents a simple but effective procedure for the management of this complex condition.
