Insights
Radiologists use various imaging techniques to diagnose pediatric and adult cardiovascular diseases. Recognizing specific imaging signs is crucial for identifying congenital heart anomalies.
Area of Science:
- Radiology and Cardiology
Background:
- Cardiovascular imaging is a dynamic field requiring expertise in pediatric and adult cardiovascular diseases.
- Familiarity with chest radiographs, CT, MRI, and angiography is essential.
Purpose of the Study:
- To highlight key cardiovascular imaging signs of congenital anomalies.
- To aid radiologists in accurately identifying thoracic heart and vessel abnormalities.
Main Methods:
- Review of common cardiovascular imaging modalities (radiography, CT, MRI, angiography).
- Correlation of characteristic imaging findings with specific congenital heart diseases.
Main Results:
- Specific imaging signs associated with common congenital anomalies are described: egg on a string (transposition of great arteries), snowman (total anomalous pulmonary venous return), scimitar (partial anomalous pulmonary venous return), gooseneck (endocardial cushion defect), figure of three (aortic coarctation), boot-shaped heart (tetralogy of Fallot), and box-shaped heart (Ebstein anomaly).
Conclusions:
- Recognition of these classic imaging signs aids in the prompt diagnosis of congenital cardiovascular diseases.
- Understanding the pathophysiologic basis of these signs enhances diagnostic accuracy in pediatric and adult patients.
Abstract:
Cardiovascular imaging is a rapidly evolving field that requires familiarity with the appearances of pediatric and adult cardiovascular diseases on chest radiographs as well as images obtained with computed tomography, magnetic resonance imaging, and angiography. To accurately identify congenital abnormalities affecting the heart and vessels of the thorax, radiologists must recognize the imaging features and understand their pathophysiologic origin. The cardiovascular imaging signs of congenital anomalies that are most often seen in radiologic practice include the egg on a string (seen in transposition of the great arteries), snowman (total anomalous pulmonary venous return), scimitar (partial anomalous pulmonary venous return), gooseneck (endocardial cushion defect), figure of three and reverse figure of three (aortic coarctation), boot-shaped heart (tetralogy of Fallot), and box-shaped heart (Ebstein anomaly).

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
