  1. Transposition of the great arteries
  2. Truncus arteriosus

  4. Tetralogy of Fallot
  5. Persistent fetal circulation

tricuspid atresia
all other causes will result in enlarged right ventricle and right axis deviation but only tricuspid atrsia will result in left axis deviation due to atrophied right ventricle
