JEN STIFFLER: My husband Sean and I, we have three kids, Wade, Scout, and Penn. We had our third and she was our second to be born with an undiagnosed congenital heart defect. And hers was much more serious than Scout's. 

She was born with essentially half a heart. It's called hypoplastic right heart syndrome. They said, what hospital would you like to go to? And my husband and I both said immediately, UVA. 

There was one doctor who thought that they could balloon open her right ventricle. And so, if we could get blood flow into the heart, there was a chance that we could give her enough time to have her heart grow. 

It worked. It worked beautifully. Her heart has grown to normal size because of that cath procedure. They took something that is so scary, it's your worst nightmare as a parent, and they made us feel comfortable.
