Insights

Interrupted aortic arch typically presents in infancy. This rare case highlights unusual childhood presentation with intact ventricular septum and persistent carotid ducts, visualized by cardiac MRI.

Area of Science:

  • Cardiovascular Medicine
  • Pediatric Cardiology
  • Medical Imaging

Background:

  • Interrupted aortic arch (IAA) is a rare congenital heart defect.
  • Typical presentation occurs in early infancy due to reliance on the arterial duct.
  • Most IAA cases involve intracardiac anomalies like ventricular septal defects.

Observation:

  • This study reports an uncommon childhood presentation of IAA.
  • The patient presented with an intact ventricular septum.
  • Unusual bilateral collateral arteries, consistent with persistent carotid ducts, were observed.

Findings:

  • Cardiac MRI angiography with 3D reconstruction precisely located the aortic arch interruption.
  • The imaging delineated the extensive collateral circulation, including the persistent carotid ducts.
  • This case demonstrates a unique collateral pathway in IAA.

Implications:

  • Childhood presentation of IAA suggests significant collateral circulation development.
  • Persistent carotid ducts represent an unusual collateral pathway in IAA.
  • Cardiac MRI is crucial for defining complex aortic arch anatomy and collateral networks in rare pediatric cardiovascular conditions.

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
