In brief: Flow demands

The fetal heart is required to do about half the work of living outside.
Blood from the body is pumped through the heart back to the body & placenta without going through the lungs. Mom also does the work of providing nutrients, removing waste & keeping temperature stable. After birth, the heart must pump thru the lungs & do more work. The additional load can lead the heart to fail.
