My daughter is 4-months old, was born with a heart murmur and after an echo was told it was a VSD (at about 2-months old). We just had another check up, our doctor says she can still hear the murmur, but it is small and won't need any kind of surgery. We have another echo scheduled next week, and if all is OK (the hole is not close to the ventrical) then we won't have another cardioligist appt until she is 3-years old. Odd are, the tell us, that it will close within a year to 3-years. And, even if it doesn't, no surgery needed and no real affect to her every day life. Will only have to take antibiotics when going to the dentist.
I think time will be the best test. They told us, all babies are born with holes in their hearts, some just close slower than others, and some never close. Time will tell.
Good luck, I know the worry you are going through, it is all to recent for me.
