What Causes Coarctation Of The Aorta?


There is an increased chance of having the condition if another family member has it. It also occurs more often in certain genetic syndromes such as Turner Syndrome. Coarctation of the aorta is often linked to other cardiac defects.

What age does coarctation of aorta present?

Aortic coarctation is one of the more common heart conditions that are present at birth (congenital heart defects). This abnormality accounts for about 5% of all congenital heart defects. It is most often diagnosed in children or adults under age 40.

Can coarctation of the aorta be cured?

Twenty years ago, surgery was the only treatment available for aortic coarctation. Surgery is still considered the gold standard, but today treatment options for adults with this condition also include balloon angioplasty, stenting, stent grafting, or hybrid repair (a combination of open surgery and stent grafts).

How long can you live with coarctation?

Individuals with coarctation of the aorta have historically had poor long-term out- comes with a mean life expectancy of 35 years. Natural history studies demon- strated 90% of individuals dying before age 50 years.

Can coarctation be detected before birth?

Coarctation of the aorta is one of the most difficult cardiac defects to diagnose before birth, as in some cases features may only be evident in the third trimester, with some after delivery. Antenatal detection is of paramount importance as once diagnosed, care and treatment can begin as soon as they are born.

What does coarctation mean in english?

: a stricture or narrowing especially of a canal or vessel (such as the aorta)

What causes coarctation of the aorta in babies?

What causes coarctation of the aorta? Coarctation of the aorta may be due to improper development of the aorta in the first eight weeks of fetal growth. Congenital heart defects, like coarctation of the aorta, usually occur by chance, with no clear reason for their development.

Where is coarctation of the aorta located?

Coarctation of the aorta is a narrowing of the aorta, the main artery that delivers oxygen-rich (red) blood to the body. A coarctation is located just past the aortic arch, which has branches providing blood to the head and arms.

How is coarctation of the aorta detected?

Tests to confirm a diagnosis of coarctation of the aorta may include:

  1. Echocardiogram. …
  2. Electrocardiogram (ECG). …
  3. Chest X-ray. …
  4. Magnetic resonance imaging (MRI). …
  5. Computerized tomography (CT) scan. …
  6. CT angiogram. …
  7. Cardiac catheterization.

What is the life expectancy of someone with aortic stenosis?

Severe symptomatic aortic stenosis is associated with a poor prognosis, with most patients dying 2–3 years after diagnosis.

How long does surgery for coarctation of the aorta take?

The procedure takes about three to four hours. Your child will be admitted to the hospital the morning of the procedure and may return home the following morning. To perform cardiac catheterization, a tiny incision is made in the groin to insert thin, flexible tubes, called catheters.

Does coarctation of the aorta require surgery?

Coarctation of the aorta is a birth defect in which a part of the aorta is narrower than usual. If the narrowing is severe enough and if it is not diagnosed, the baby may have serious problems and may need surgery or other procedures soon after birth.


Which syndrome is associated with coarctation of aorta?

Coarctation of the aorta is the most common cardiac defect associated with Turner syndrome.

Is coarctation of aorta fatal?

COA must be treated quickly because it can cause high blood pressure and enlarge the heart. It also can cause dissection or rupture of the aorta, which can be fatal. Severe coarctations usually are found shortly after birth and repaired by surgery immediately.

How can you tell if your baby has a heart problem?

Signs and symptoms

swelling of the legs, tummy or around the eyes. extreme tiredness and fatigue. a blue tinge to the skin or lips (cyanosis) tiredness and rapid breathing when a baby is feeding.

Why is there Rib notching in coarctation of aorta?

Bilateral symmetrical rib notching, readily appreciated on the chest image, is diagnostic of aortic coarctation. It is the result of obstruction of blood flow at the narrowed aortic segment, in conjunction with collateral blood flow through the intercostal arteries.

What does present from birth mean?

Congenital refers to something present at birth but not necessarily inherited from the parents.

What is AR in heart disease?

Aortic valve regurgitation — or aortic regurgitation — is a condition that occurs when your heart’s aortic valve doesn’t close tightly. As a result, some of the blood pumped out of your heart’s main pumping chamber (left ventricle) leaks backward.

Can coarctation of the aorta be seen on ultrasound?

Coarctation of the aorta can be suspected during a routine prenatal ultrasound or after a fetal echocardiogram (focused ultrasound of the fetal heart performed by a fetal cardiologist).

How does a PDA help coarctation of the aorta?

The PDA is a connecting vessel between the pulmonary artery (the blood vessel that carries lower oxygen carrying blood to the lungs) and the aorta. When the PDA closes, the area of narrowing can become worse, and the left ventricle has to pump against a higher body blood pressure.

Is coarctation of the aorta ductal dependent?

Coarctation may be caused by the presence of extra ductal tissue extending into the adjacent aorta which results in aortic narrowing as the ductal tissue contracts. In babies with coarctation, the aortic arch may also be small (hypoplastic).

Can you live with coarctation of aorta?

Conclusion: Surgical repair of aortic coarctation is a relatively safe surgery, however patients maintain risks of arterial hypertension, re-coarctation and mortality at long term. Nevertheless, patients report a quality of life that is no different than healthy population.

Is coarctation of the aorta the same as aortic stenosis?

This spectrum is dichotomized by the idea that aortic coarctation occurs in the aortic arch, at or near the ductus arteriosis, whereas aortic stenosis occurs in the aortic root, at or near the aortic valve.
