Aortic Stenosis Child
The aortic valve is made up of three cusps that open and close together. In babies, AS is caused by a birth defect that may result in:
- One cusp that cannot open as fully as three cusps
- Two cusps that are damaged
- Cusps that are partly closed or do not open the right way due to thickness
The valve can also be damaged by infection.
Mild AS may not cause any problems. More severe AS may cause:
- Severe lack of energy after activity
- Lightheadedness with activity
- Fainting with activity
- Rapid or irregular heartbeat
- Shortness of breath
- Pain, squeezing, pressure, or tightness of the chest, usually with activity
Rarely, AS may cause heart rhythm problems and sudden death.
Mild AS will be monitored for any changes or problems. Treatment may not be needed right away.
Choices for moderate to severe AS are:
- Lifestyle changes, such as avoiding strenuous activities
- Medicine to lower stress on the heart and lower the risk of heart failure
Some children may need surgery. Choices are:
- Balloon valvuloplasty to open the aortic valve or make it bigger
- Aortic valve replacement to replace a defective heart valve
