Answers
Answer:
Ventricular septal defects happen during fetal heart development and are present at birth. The heart develops from a large tube, dividing into sections that will eventually become the walls and chambers. If there's a problem during this process, a hole can form in the ventricular septum.

Explanation:
Reason
An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present at birth (congenital). Small defects may never cause a problem and may be found incidentally
Cause
Ventricular septal defects happen during fetal heart development and are present at birth. ... If there's a problem during this process, a hole can form in the ventricular septum. In some cases, the tendency to develop a VSD may be due to genetic syndromes that cause extra or missing pieces of chromosomes
