What is Aortic narrowing?

21:56 - 4 May , 2021


It is a congenital heart anomaly in which the aorta’s diameter narrows, causing the left side of the heart to work harder to pump blood. The reason why some children are born with this condition is unknown, but it is believed to be due to a genetic alteration at the X chromosomes, being more common in males. 

Signs and symptoms Aortic narrowing

There are usually no symptoms, but sometimes the following may occur:

  • Chest pain.
  • Fatigue and shortness of breath when doing physical activity.
  • Cold legs and feet.
  • Hypertension.

Diagnosis and treatment Aortic narrowing

This condition is usually diagnosed shortly after birth or in early childhood, but in some cases it is identified as late as adolescence or adulthood. Although serious symptoms do not appear, it is necessary to receive timely treatment because it can cause heart failure, hypertension, increased heart volume, damage or rupture of the aorta, threatening the patient’s life. 

The pediatrician will physically assess your child and request laboratory and imaging tests, such as X-rays, cardiac ultrasound, MRI, or CT scan.

Aortic narrowing repair is done through a surgical technique called angioplasty or balloon dilation, a stent can also be placed to keep the opening achieved. 

Once the abnormality is corrected, your child should receive regular medical supervision to monitor his or her blood pressure and rule out the possibility of this condition developing again.

It is essential that during the first months after surgery, you do not allow your child to engage in physical activities and prevent him or her from receiving blows to the chest.
