The role of MDCT in the assessment of cardiac and extra-cardiac vascular defects among Egyptian children with tetralogy of Fallot and its surgical implementation

Abstract Background Tetralogy of Fallot (TOF) is considered the most common form cyanotic congenital heart diseases (CHD), accounting for about 10% cases. It includes four main cardiac defects, in addition to various extra-cardiac anomalies. Aim This study aimed evaluate and vascular defects associated with TOF among Egyptian children, regarding frequency types assessment multi-slice or multi-detector computed tomography (MDCT) role their diagnosis. Definitely, full detection these anomalies has utmost importance when evaluating such patients particularly before surgical intervention. Methods included 60 pediatric diagnosed as TOF, who underwent MDCT examination our institute during period 6 months from (March September 2020), confirm trans-thoracic echocardiography (TTE) findings detect other abnormalities which cannot be precisely detected TTE interventions. Results The incidence different by was 85% significantly higher than that (55%). Moreover, superior regards its diagnostic accuracy (96.6% vs. 80%), sensitivity (98% 76.9%), specificity (88.9% 85.7%), both positive negative predictive values. were affecting pulmonary artery (80%), followed aorto-pulmonary vessels (45%), then aortic (40%), coronary arteries (20%), lastly vena cava connection (6.7%). Patients’ demographic characteristics clinical presentations also presented. Conclusion confirmed many are commonly associating lesions emphasizing great value Certainly, proper will help decision-making preoperative evaluation, corrective interventions, further management
