Abstract
Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD) and represents 10% of all CHD, it needs proper pre surgical evaluation. Multi detector computed tomography (MDCT) has become an essential tool to evaluate the TOF and its associations and extra cardiac vascular abnormalities including the pulmonary arterial tree, major aorto-pulmonary collateral arteries (MAPCAs) and patent ductus arteriosus (PDA).
Results: Multi detector cardiac computed tomography (MDCT), with its superior spatial and temporal resolution, has become a valuable modality in evaluating the cardiovascular complex morphology of TOF, especially the extra cardiac associations as well as the pulmonary artery anatomy and aorto-pulmonary collateral vessels.
Conclusion MDCT proved to be a precious modality for decision-making in TOF patients; MDCT affords many advantages in comparison with echocardiography, MDCT is a non-operator dependent exam. MDCT is excellent in detecting intra-cardiac and extra-cardiac anomalies in pediatric patients with complex CHD such as TOF. It affords comprehensive anatomical information on coronary arteries abnormalities, pulmonary arterial tree development especially distal pulmonary arteries and major aortopulmonary collaterals in fine detail as part of the surgical preparation for TOF & pulmonary atresia.
