Hi,
Some heart problem was detected in the fetus. From the description you have given, it looks more like partial anomalous pulmonary venous connection(PAPVC), where there will be abnormal
drainage of pulmonary vessels into the heart.
Scimitar syndrome is one of the type of PAPVC, where right
pulmonary vein drain into
inferior vena cava (large blood vessel draining lower part of body ) instead of right heart.
Usually, children with scimitar syndrome may have recurrent chest infections and raised pulmonary pressures due to increased blood flow to the lungs.
With surgical correction of abnormal drainage, children will do better, provided their lung development is normal and no other associated anomalies.
I know its very distressing thing to know for parents but don't lose hope, your baby will be alright. Scimitar syndrome will not be inherited to subsequent children. Risk of other children getting is very very low.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nirubhan Bharathy, Pediatrician
