Noninvasive imaging of isolated persistent fifth aortic arch

Area of Science:

• Cardiology
• Pediatric Cardiology
• Medical Imaging

Background:

• Congenital heart defects represent a significant area of pediatric cardiovascular research.
• The persistent fifth aortic arch is an exceedingly rare congenital anomaly with limited documented cases.
• Accurate diagnosis of rare cardiac malformations is crucial for appropriate management.

Observation:

• Echocardiography initially suggested the presence of a persistent fifth aortic arch in an infant presenting with a heart murmur.
• Magnetic resonance imaging (MRI) provided definitive confirmation of this rare congenital anomaly.
• The infant's clinical presentation included a notable heart murmur, prompting diagnostic investigation.

Findings:

• The study successfully confirmed a diagnosis of persistent fifth aortic arch.
• Magnetic resonance imaging (MRI) was instrumental in visualizing and confirming the anomaly.
• Three-dimensional reconstructions from MRI data offered detailed anatomical insights.

Implications:

• This case contributes to the limited literature on persistent fifth aortic arch, enhancing understanding of its presentation.
• Advanced imaging techniques like MRI are vital for diagnosing rare and complex congenital heart diseases.
• Increased awareness of such rare anomalies can improve early detection and clinical management in infants.
