Tetralogy Of Fallot

Tetralogy of Fallot is a rare condition caused by a combination of four heart defects that are present at birth (congenital).These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and to the rest of the body.

Symptoms
  • A bluish coloration of the skin caused by blood low in oxygen (cyanosis)
  • Shortness of breath and rapid breathing, especially during feeding or exercise
  • Loss of consciousness (fainting)
  • Clubbing of fingers and toes — an abnormal, rounded shape of the nail bed
  • Poor weight gain
  • Tiring easily during play or exercise
  • Irritability
  • Prolonged crying
  • A heart murmur
  • Tet spells
Diagnosis
  • Physical examination
  • Echocardiography
  • Electrocardiogram
  • Chest X-ray
  •  Oxygen level measurement (pulse oximetry). 
  • Cardiac catheterization
Treatment
  • Intracardiac repair
  • Open-heart surgery
  • Temporary surgery
