Signs and symptoms of deterioration
- Shortness of breath
- Increased leg edema
If you frequently experience one of these signs and symptoms, call your cardiologist as soon as possible.
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.
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
| 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.
