Tetralogy of Fallot (TOF) is the first described and most common cyanotic congenital heart anomaly that generated successful surgical palliation procedure definitive intracardiac repair. Classical TOF comprises four typical features right ventricular outflow tract obstruction (RVOTO), hypertrophy (RVH), septal defect (VSD) aortic dextroposition. Complex forms condition include associated with absent pulmonary valve atresia (TOF-PA) or without major aortopulmonary collateral arteries (MAPCAs). The pathophysiological understanding tetrad basically sequel a singular abnormality infundibular malformation, anterior deviation septum, had consequences improved survival. Diagnostic functional imaging play key role in clinical management patients TOF. We revisit traditionally employed modalities (echocardiography cardiac catheterisation) only briefly as these remain within domain cardiology practice. emphasis present review to outline computed tomographic angiography (CTA) evaluation TOF, special reference technical considerations best practice recommendations.
