Signs and symptoms of deterioration

  • Shortness of breath
  • Increased leg edema
  • Palpitations

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

Exercise recommendations

Mild or moderate stenosis: there are no particular restrictions

Severe stenosis: you may have some physical restrictions, such as no weight bearing. 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

Mild or moderate stenosis : pregnancy is well tolerated by most women.

Severe stenosis : pregnancy may have mortality and morbidity risks.

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

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.
