a. The child's heart needs to strengthen and grow to survive the surgery.
b. There is the possibility of a spontaneous closure in the first 2 years of life.
c. Parental separation is traumatic for the child, potentially increasing the workload of the heart.
d. This gives the parents time to adjust to the idea, and separation for the child is easier.
