What is the prevalence of Tetralogy Of Fallot?

Tetralogy of Fallot is a relatively rare congenital heart defect that affects the structure of the heart and its blood vessels. It is estimated to occur in about 5 to 7 out of every 10,000 live births, making it one of the most common cyanotic heart defects in children.

This condition is characterized by a combination of four heart abnormalities, which include a ventricular septal defect (a hole in the wall separating the heart's lower chambers), pulmonary stenosis (narrowing of the pulmonary valve and artery), overriding aorta (the aorta is positioned over both ventricles instead of just the left), and right ventricular hypertrophy (thickening of the right ventricle).

Tetralogy of Fallot can vary in severity, with some individuals experiencing mild symptoms while others may have more severe complications. Early diagnosis and appropriate medical intervention are crucial for managing this condition. Surgical correction is typically required to repair the heart defects and improve blood flow.

While the prevalence of Tetralogy of Fallot is relatively low compared to other congenital heart defects, it remains an important condition that requires medical attention and ongoing care.
