Preoperative diagnosis of extra-cardiac malformations is essential for surgical planning. Computed tomography (CT) cardiac angiography plays an essential role in CHD, especially for assessing the extra-cardiac manifestations of CHD. Complex cardiovascular anatomic features and extra-cardiac manifestations identified with CT angiography(CTA) are sometimes more useful in decision-making in surgical procedures,this study aimed to detect the role of CT angiography in diagnosis of coronary artery anomalous origins and extracardiac vascular malformation of congenital Heart disease in pediatric age group
Methods:
 This prospective study was conducted in the Department of Radiodiagnosis at Benha university hospital Cases were selected randomly from Pediatric patients with known congenital cardiac disease for whom echo were referred to CT cardiac angiogram for extracardiac anomalies work up in the department of jan 2021 to may 2024, 50 consecutive patients (male 23, female 27); with age ranging from 4 months to 11 years were diagnosed with congenital complex cardiac malformations on clinical assessment or echocardiography with suspected intrathoracic extra-cardiac vascular anomalies, All the angiogram was done with All CT examinations were performed using Multi Detector CT(MDCT )(GE 128 slice CT scan
