I didn't really know (okay, I had no clue!) what a VSD was, so I figured I'd educate you all along with myself. Basically, it's a hole in the wall (septum) separating the two lower chambers of the heart. Normally, the wall closes before birth, so the oxygen-rich blood on the left side can't mix with the oxygen-poor blood on the right side. A VSD causes the heart to have to work harder to provide oxygen to the body's tissues.
Our girl's VSD was diagnosed because she had an ongoing heart murmur, an extra or unusual sound heard with her heartbeat. Other symptoms include shortness of breath or poor eating, but we don't know that she had problems with that. This is a very common heart defect; about 1 in 500 babies are born with it.
We had a couple of cardiologists review our girl's file, which included results of her echocardiogram after the surgery, and they said everything looked great. We already know that Children's Hospital here in Denver is awesome, so we'll definitely be taking her to the cardiology department there for a check-up right when she gets home. But overall, we're very happy that she's so healthy, she didn't (and won't) have to have open-heart surgery, and that her prognosis seems so positive!
