Fallot's tetralogy

Case contributed by Dr Mohammad A. ElBeialy

Presentation

Cyanotic baby.

Patient Data

Age: 1 year.
Gender: Male
Modality: X-ray

Conventional radiograph shows typical boot-shaped heart with upturned cardiac apex indicative of right ventricular hypertrophy as well as concave pulmonary arterial segment indicative of pulmonary hypoplasia.

Modality: CT
  • A large subaortic ventricular septal defect (VSD) with an over-riding aorta. The over-riding aorta is dilated and measures 1.6 cm in its maximal diameter at the level of the main pulmonary artery (MPA).
  • Antegrade continuity between the right ventricle (RV) and MPA with severe infandibular and valvular pulmonary stenosis.
  • Confluent relatively small sized MPA with fair caliber of its major branches.
  • Left-sided aortic arch with common bovin origin of the left CCA and the brachiocephalic artery. 
  • Mild cardiomegaly with right ventricular hypertrophy.
  • Situs solitus, apex to the left.
  • Atrio-ventricular and ventriculoarterial concordance.
  • No evident anomalous pulmonary venous drainage.
  • No PDA.
  • No major aorto-pulmonary collaterals (MAPCAs).

Case Discussion

A typical case of tetralogy of Fallot (TOF) with subaortic VSD, over-riding aorta, pulmonary stenosis and RVH.
