Pediatric aortic stenosis

21:56 - 4 May , 2021

Disease

What is Pediatric aortic stenosis?

It is a malformation of the aortic valve that produces a partial obstruction in blood flow, causing the heart to overwork to pump enough blood for the body. In children born with this defect, their aortic valve has only two cusps instead of three. 

There are several factors that can cause this congenital disease, but it is usually due to genetic issues such as a chromosomal abnormality. In the case of aortic stenosis that develops after birth, it can be caused by a strep infection that causes rheumatic fever.

Symptoms

When the valve narrowing is mild, some children and adults may not have symptoms, but in severe cases where the obstruction is significant, the following may be experienced:

  • Heart failure.
  • Lack of appetite and slow development. 
  • Respiratory problems.

Diagnosis and treatment

Currently, it is possible to identify aortic valve stenosis before the baby is born through fetal cardiac ultrasound. If it is not detected before birth, the pediatrician will physically assess your child and request laboratory and imaging tests, such as a chest x-ray, electrocardiogram, cardiac ultrasound, or cardiac catheterization. 

The treatment will be based on the tests’ results, your child’s age, health status, and expectations for the development of the disease, and it may include medication and surgical repair of the blocked valve so blood can circulate normally.

Most children with aortic stenosis surgery lead normal lives, but for several months they will need to take blood thinners and have continuous medical check-ups for life.

Our Pediatric Heart Center is the only private center in Mexico to treat heart conditions with an exclusive unit for pediatric surgeries.

We have a group of highly trained specialists made up of pediatric cardiologists, echocardiographers, interventional cardiologists, electrophysiologists, pediatric cardiovascular surgeons, pediatric cardiovascular anesthesiologists, pediatric specialists in cardiovascular intensive care, nurses, medical assistants, perfusionists, psychologists, and social workers.
