Summary
Multidetector computed tomography (MDCT) effectively diagnoses interruption of the aortic arch (IAA) in neonates. This imaging modality provides sufficient information for surgical planning, potentially eliminating the need for cardiac catheterization.
Area of Science:
- Medical Imaging
- Pediatric Cardiology
- Radiology
Background:
- Interruption of the aortic arch (IAA) is a critical congenital heart defect requiring timely diagnosis and surgical intervention.
- Accurate preoperative assessment is crucial for successful surgical repair of IAA.
Purpose of the Study:
- To evaluate the utility of multidetector computed tomography (MDCT) for the preoperative diagnosis of interruption of the aortic arch (IAA).
Main Methods:
- Retrospective analysis of seven neonates diagnosed with IAA.
- Enhanced MDCT imaging performed using 16- or 64-MDCT scanners prior to surgical repair.
- MDCT procedures were conducted without electrocardiographic gating or respiratory arrest.
Main Results:
- High-quality CT images were obtained in all seven neonates.
- MDCT accurately classified IAA types: one case of Type A and six cases of Type B (Celoria and Patton classification).
- Surgical confirmation validated the MDCT-based classification of IAA types and subtypes.
Conclusions:
- MDCT provides sufficient diagnostic information for preoperative assessment of IAA in neonates.
- MDCT can potentially replace cardiac catheterization as a preoperative diagnostic tool for IAA, streamlining surgical planning.

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...
01:28Imaging 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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
