    Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, [ 9 ] is a congenital heart defect characterized by four specific cardiac defects. [ 4 ] Classically, the four defects are: [ 4 ] pulmonary stenosis, which is narrowing of the exit from the right ventricle; a ventricular septal defect, which is a hole allowing blood to flow ...

    The congenital heart block is a rare disease that affects around 1 child in every 15,000–20,000 births. [3] However, its high mortality (which can be as high as 85% in some severe cases) makes the early diagnosis and intervention very important.
