Signs and symptoms of deterioration

  • Chest pain
  • Shortness of breath
  • Dizziness
  • Exercise intolerance
  • Loss of consciousness
  • Palpitations

If you frequently experience one of these signs and symptoms, call your cardiologist as soon as possible.

Exercise recommendations

Mild stenosis: there are no particular restrictions

Moderate or severe stenosis: competitive and contact sports are not recommended. Please ask your cardiologist about your specific restrictions.

Endocarditis recommendations

Antibiotics are recommended before particular dental and surgical procedures.

You should always maintain good oral hygiene in order to prevent infection.

Pregnancy and contraception

Your risk level depends on the severity of the aortic stenosis

A pre-conception cardiology counseling is necessary and very important.

Risks of transmission

Normal population 1%
1 child affected 2%
2 children affected 15%
3 children affected 50%
Mother with malformation Up to 15%
Father with malformation Up to 12%
Marfan’s Syndrome, bicuspid valves Up to 50%

These numbers are approximate. A fetal echocardiogram is recommended between the 18th and the 20th week of pregnancy to detect possible cardiac malformations in the baby.

The risk of transmission varies according to the family antecedents. In case of doubts, a consultation with a geneticist is recommended in order to precisely calculate the risks and to make specific recommendations.
