Aortic arch interruption in infancy: radio- and angiographic features

|November 1, 1980
Summary
Interrupted aortic arch in infants is often associated with other heart defects. Left ventriculography is key for diagnosis, supporting theories on fetal blood flow affecting aortic arch development.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Interrupted aortic arch (IAA) is a rare congenital heart defect.
- It requires prompt diagnosis and management in neonates.
- Understanding associated anomalies is crucial for surgical planning.
Purpose of the Study:
- To review the radio- and angiocardiographic features of infants with interrupted aortic arch.
- To identify common associated cardiovascular anomalies.
- To evaluate the diagnostic utility of imaging modalities.
Main Methods:
- Retrospective review of 19 infants diagnosed with interrupted aortic arch.
- Analysis of radiographic and angiocardiographic findings.
- Correlation of imaging findings with clinical data.
Main Results:
- Fifteen infants had Type B IAA (between left carotid and subclavian arteries).
- Ventricular septal defect (19/19) and patent ductus arteriosus (18/19) were most common.
- Left ventriculography was diagnostic for IAA and other abnormalities.
Conclusions:
- Plain film findings for IAA are nonspecific.
- Left ventriculography is essential for diagnosing IAA and associated defects.
- Findings support the theory linking decreased fetal ascending aorta flow to IAA development.
