It is impossible to tell whether the baby's heart defect was something that will happen again or not, you need to ask your doctor why it happened and if he or she thinks it is likely to happen to another baby.  The fact that you have one child without a heart problem makes it seem like the second child's problems were not something that is chromosomal, but your doctor should be the one to assess this.
