This journey began when Tess had her 2 month wellness check and her pediatrician heard a "flow" that was slightly abnormal, "but nothing to worry about" and referred us to Children's Hospital Heart Institute. He was adamant that we shouldn't worry and could even wait to see someone until after her 4 month check so he could see if it was still an issue. We decided to go ahead with the eval since I was already mental about it. Plus, there is a slight family history of issues, though not serious, but I have a mitral valve prolapse and even though it is mild and a non issue, we want to make sure she is as fine as possible and if not, catch it and treat it as early as possible. Knowing these tests were non invasive also helped convince us to do it now instead of later.
So today was her evaluation. It was an interesting trip. First, beyond emotional was I...goodness, between wanting to throw up or cry, my body couldn't decide which to do. Luckily I just cried. It started when the nurse brought us into the room. The tears were flowing. I apologized, just let her know I was worried. She was wonderful and very comforting.
They checked Tess' blood pressure which I assume was fine as they said nothing to us about that. Then we moved into another room. It was time for her echocardiogram. Another room, with a naked baby. They hooked her up to a machine and we got to watch her heart on the ultrasound machine. Lots of blue and red colors and movement. I could see 4 chambers, that made me happy.

Then back to the second room. Then came in the EKG machine. They hooked up, I think 12 electrodes to her tiny little chest with wires coming off all of them. This took about 30 seconds once she was still. So far so good.

Then came in a cardiology resident. He examined her and asked us questions, was also very nice. While he was listening to her chest he commented that he heard the same thing her pediatrician heard and that "I don't think it's anything to worry about". In comes the cardiologist.
She was very quiet, somewhat impersonal. Not reassuring. She listened to her chest. Mumbled some medical terms to the Resident. She then asked him if he "heard the clicking", he said no and they both listened some more. Then she said, to him, nothing really to us at this point, "we need to go get the diagram". Out they both go. After a minute of me freaking out in my head "my kids heart is not supposed to click!!!" I kept screaming in my brain....she came back in and said "she's ok" or "she'll be fine", something to that effect. I let her know, politely, that she may want to lead with that next time. Here comes the waterworks again.
She proceeded to tell us that there are two issues. 1) (pulmonary stenosis) she has a slight "clicking" in her pulmonary valve which indicates that this valve is "thicker" than normal, but not an issue. She said this is something that "only improves with age" and is so minor that nothing needs to be done. 2) (atrial septal defect) every baby is born with a small hole separating the top two chambers of the heart; majority of babies this closes on it's own shortly after birth. Hers has not closed yet, and she actually has "several very small holes" all along this portion. Again, she says "they are so small we don't need to do anything" and assures us that Tess will likely outgrow both of these going on to lead nothing short of healthy and happy life, and likely not have these issues in the future.
We do a re-check in 6 months. Tess is growing very beautifully, eating, sleeping, and acting perfectly. There is nothing to be concerned about for her and like the doctor said, she will probably outgrow both of these conditions.
As far as what caused these, from what I can tell from online information, these are both genetic or random occurances that happen in utero before 8 weeks! They don't really know the cause.
Here are some websites if you want to know more about either of these conditions. For both, she has very MILD cases.
