LEFT CARDIAC AXIS DEVIATION  

 

 

 

 

 

 

 

CARDIAC CAUSES
  • Isolated cardiac defects.
    • Tetralogy of Fallot.
    • Transposition of the great vessels.
    • Double outlet right ventricle.
    • Hypoplastic left heart syndrome.
    • Ebstein's anomaly.
    • Cardiomegaly.
  • Cardiac + extra-cardiac defects.
    • Tetralogy of Fallot + diaphragmatic hernia.
    • Double outlet RV + choroid plexus cyst + abnormal extremities (trisomy 18).
    • Double outlet RV + renal agenesis.
    • Transposition of great vessels + omphalocele.
    • VSD + omphalocele.
    • LV aneurysm and omphalocele (trisomy 13).
    • Cardiomegaly + VSD + vein of Galen AVM

 

NORMAL HEART
  • Extracardiac defects.
    • Omphalocele.
    • Caudal regression.
    • Meconium ileus.
