Insights

The bovine aortic arch is more common in children with coarctation of the aorta. Multislice computed tomographic angiography is recommended for precise anatomical assessment before interventions.

Area of Science:

  • Cardiology
  • Radiology
  • Pediatric Congenital Heart Disease

Background:

  • Coarctation of the aorta is a congenital heart defect.
  • The bovine aortic arch is an anatomical variation of the aortic arch branching pattern.
  • Understanding the association between these two conditions is crucial for surgical planning.

Purpose of the Study:

  • To determine the frequency of the bovine aortic arch in pediatric patients with coarctation of the aorta.
  • To compare the incidence of bovine aortic arch in patients with and without coarctation.
  • To evaluate the association between aortic arch branching patterns and other congenital heart anomalies.

Main Methods:

  • Retrospective analysis of computed tomographic angiography reports.
  • Inclusion of 700 pediatric patients with congenital heart diseases over a 10-year period.
  • Identification and quantification of coarctation of the aorta and bovine aortic arch prevalence.

Main Results:

  • Out of 700 patients, 117 (16.71%) had coarctation, and 19 (2.71%) had a bovine aortic arch.
  • In patients with coarctation, 7 (5.98%) had a bovine aortic arch.
  • Patients with coarctation and a normal branching pattern showed a higher incidence of atrial septal defect, ventricular septal defect, and anomalous pulmonary venous return compared to those with a bovine aortic arch.

Conclusions:

  • The bovine aortic arch occurs more frequently in patients with coarctation of the aorta.
  • Multislice computed tomographic angiography is a valuable noninvasive tool for delineating aortic arch anatomy in patients with coarctation.
  • Accurate pre-procedural anatomical assessment is essential for effective management of coarctation of the aorta.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

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,...

Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...
