Insights
Persistent Truncus Arteriosus is a rare, severe congenital heart defect where one artery supplies blood to the body and lungs. Early diagnosis by radiologists and cardiologists is crucial for infant survival.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Persistent Truncus Arteriosus (PTA) is a critical cyanotic congenital heart anomaly.
- It involves a single great artery arising from the heart, supplying both pulmonary and systemic circulations.
- While hemodynamically stable in utero, PTA poses a significant postnatal threat, with an 80% mortality rate in untreated infants within the first year.
Abstract:
Persistent Truncus Arteriosus is a cyanotic congenital heart anomaly in which a single trunk supplies both the pulmonary and systemic circulation, instead of a separate aorta and a pulmonary trunk. It is usually classified as a conotruncal anomaly. Due to parallel fetal circulation, truncus arteriosus does not cause any haemodynamic problem in utero. However it is a major problem postnatally and, if left untreated, approximately 80% of infants die within the first year. Diagnosis should be made early by radiologists and cardiologists due to fatal illness. We found it valuable to present a case of truncus arteriosus with computerized tomography findings because of its rare occurrence.

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...

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...
