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.
