Our expert says:
I was sorry to learn about the loss of your little son. The condition is not a simple genetic disorder and the chances of recurrence in any of your future pregnancies are less than one in forty.
Genetic manipulation is not feasible, but antenatal diagnosis of congenital heart abnormalities in the unborn child can be achieved by means of ultrasonic investigations during pregnancy. In these circumstances, it is essential that you inform the ultrasonologist that the foetal heart needs to be specially checked.
In response to you second question, aortic arch interruption or coarctation is caused by faulty foetal development in the first few weeks after conception.
Kind Regards, Maritha
