Aortic Stenosis

Also known as: Aortic valve stenosis, calcific aortic stenosis

What is ​Aortic Stenosis?

The aortic valve separates the heart's left ventricle from the aorta, which takes blood to the rest of the body. When someone has aortic stenosis, the aortic valve doesn't open as wide as it should. This prevents blood from flowing out of the heart at its customary rate.

What causes aortic stenosis?

In most children the cause isn't known. In some cases, aortic regurgitation occurs as the result of a birth defect. Other times, calcium deposits over time cause the valve to become more narrow (calcific aortic stenosis). Finally, some diseases, such as rheumatic fever, cause aortic stenosis as a complication.

What are the symptoms of aortic stenosis?

Many children will have no symptoms. Possible symptoms of aortic stenosis include chest pain or discomfort, fatigue or breathing problems, coughing, fainting, weakness or dizziness.

What are aortic stenosis care options?

Medications can be used to treat the symptoms of aortic stenosis. Surgery or a procedure called balloon valvuloplasty can also be used to repair the valve.

What are aortic regurgitation care options?

Mild cases are often treated with medications. More severe cases of aortic regurgitation may require surgical repair.

Balloon valvuloplasty is a medical procedure that is used to try to correct a heart valve that is either stiff or narrow by using a balloon to widen the valve opening. Learn more

Ross-Konno Procedure

Ross-Konno procedure is a surgery to repair a damaged aortic valve. The aortic valve is responsible for pumping blood from the heart out to the body. The left ventricular outflow tract is also enlarged as part of the Ross-Konno procedure. Learn more

Subaortic Membrane Resection

Subaortic membrane resection is a surgery that’s used to repair a medical condition known as subaortic stenosis. With subaortic stenosis, the area just below the aortic valve of the left ventricle is obstructed or narrowed often by excess tissue, which reduces the flow of blood to the body. Learn more
