Can a PDA cause a asd in my baby girl?

In brief: No
They are two separate things.
The ductus (pda) is supposed to be open prior to birth. It's part of how oxygen gets pumped from the umbilical cord to the rest of the body. It's supposed to close at birth. The atrial septum is the wall between the two upper heart chambers (there are four). If it has a hole in it, that's abnormal and called an asd. It can allow blood to flow the wrong direction.

In brief: No
Though different forms of heart disease do occur together, a PDA will not "cause" a true asd.
However, a PDA can lead to blood flow changes which will keep a normal atrial communication (i.e. Pfo) open. But again, it will not cause a true asd.

Pda stands for patent (or open) ductus arteriosus.
The ductus arteriosus is a normal structure during fetal life and closes in most children after birth. It is only referrred to as a PDA after birth when it fails to close. An ASD develops in in the fetus at a time when they all have a ductus arteriosus.
