In-utero fetal cardiac surgery.
It's an interventional procedure that involves piercing the mother's abdomen to reach the fetus's heart. A special balloon is then used to open the narrowed aortic valve and restore blood flow.
This was the in-utero interventional surgery Parriott was talking about.
After talking with him in more detail, Chen Yu learned that similar procedures had been performed since the 1990s.
However, the old method involved performing a caesarean section, taking the baby out without cutting the umbilical cord, putting it on extracorporeal circulation, and after completing the open-heart surgery, putting the baby back inside.
But follow-up studies of these cases revealed that this procedure stimulated uterine contractions, leading to premature birth and fetal death.
It was only after this that research into minimally invasive interventional surgical methods began.
