I have four kids my first son was born healthy. My second child was born with a VSD and it closed up on its own by a year old. My third child (different dad than the first two) was born with a VSD and a ASD and went through heart failure had to have surgery at 2 months old. I am now expecting our fourth child (second together) and just found out that he also has a VSD and they wont know how bad it is until he is born. I just want to know why three of my kids have had it and what exactly how much the risk goes up with each child.
