The value of counter-current aortography in infants

Area of Science:

• Cardiovascular Imaging
• Pediatric Cardiology
• Interventional Radiology

Background:

• Congenital heart disease (CHD) diagnosis in infants often requires detailed anatomical visualization.
• Minimally invasive imaging techniques are crucial for reducing risks in neonates and infants.
• Aortic arch anomalies are a significant subset of congenital heart defects.

Observation:

• Counter-current aortograms were performed on five infants (1.6–2.8 kg) presenting with symptoms of congenital heart disease.
• All procedures yielded diagnostic-quality imaging.
• The technique successfully elucidated aortic arch anatomy in most cases.

Findings:

• Counter-current aortography demonstrated diagnostic quality images in 4 out of 5 infants.
• The only diagnostic failure occurred with anomalous origin of the subclavian artery.
• No procedure-related complications were observed in the study cohort.

Implications:

• Counter-current aortography is a safe and effective method for diagnosing congenital heart disease in infants.
• This minimally invasive approach aids in elucidating complex aortic arch anatomy.
• The technique offers a valuable alternative for pediatric cardiovascular imaging.
