What are the four defects in tetralogy of Fallot?

The four abnormalities that make up the tetralogy of Fallot include:

  • Pulmonary valve stenosis.
  • Ventricular septal defect.
  • Overriding aorta.
  • Right ventricular hypertrophy.

What do you mean by tetralogy of Fallot?

Tetralogy of Fallot (pronounced te-tral-uh-jee of Fal-oh) is a birth defect that affects normal blood flow through the heart. It happens when a baby’s heart does not form correctly as the baby grows and develops in the mother’s womb during pregnancy.

Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy).

Is tetralogy of Fallot fatal?

Tetralogy of Fallot (TOF) is a congenital heart defect that can be fatal if it’s left untreated. It’s also known as “tet.” The “tetra” in the name of the condition comes from the four problems associated with it. The condition is named after Dr.

Is tetralogy of Fallot curable?

Most children with tetralogy of Fallot will need surgery to fix the heart problems, and the surgery is usually performed before a baby is 1 year old. Tetralogy of Fallot can cause problems if the heart is not fixed, however, corrective surgery performed in childhood for tetralogy of Fallot does not cure the condition.

Can you live a normal life with Tetralogy of Fallot?

Conclusions: The vast majority of the patients seemed to live normal lives 20–37 years after Tetralogy of Fallot repair. Late deaths were cardiac in origin, including sudden death from arrhythmias.

Why is it important to know about tetralogy of Fallot?

Because a baby with tetralogy of Fallot may need surgery or other procedures soon after birth, this birth defect is considered a critical congenital heart defect. Congenital means present at birth. This heart defect can cause oxygen in the blood that flows to the rest of the body to be reduced.

What is the tetralogy of Fallot atresia?

Tetralogy of Fallot Stenosis at or below the pulmonary valve, or pulmonary valve atresia (absent pulmonary valve can occur but is rare). Ventricular septal defect. Aorta overriding (sitting above the) ventricular septal defect.

Can a child with Down syndrome have tetralogy of Fallot?

In most children, the cause of tetralogy of Fallot isn’t known. It’s a common type of heart defect. It may be seen more commonly in children with Down syndrome or DiGeorge syndrome. Some children can have other heart defects along with tetralogy of Fallot. How does it affect the heart?

Can a repaired tetralogy of Fallot cause dizziness?

Another problem can be a leaky pulmonary valve and enlargement of the heart’s right side. Patients with repaired tetralogy of Fallot have a higher risk of heart rhythm disturbances called arrhythmias. Sometimes these may cause dizziness or fainting.

Which features are seen with the tetrology of Fallot?

Tetralogy of Fallot is made up of the following four defects of the heart and its blood vessels: A hole in the wall between the two lower chambers-or ventricles-of the heart. A narrowing of the pulmonary valve and main pulmonary artery. The aortic valve, which opens to the aorta, is enlarged and seems to open from both ventricles, rather than from the left ventricle only, as in a normal heart.

What is an overriding aorta?

An overriding aorta is a congenital heart defect where the aorta is positioned directly over a ventricular septal defect (VSD), instead of over the left ventricle. The result is that the aorta receives some blood from the right ventricle, causing mixing of oxygenated and deoxygenated blood,…

What does tetralogy mean?
