Contrast Enhanced Computed Tomography Findings of Persistent Truncus Arteriosus; a Rare Congenital Heart Disease

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. © 2020 The Authors
