I've been meaning to update this, but keep forgetting. We found out that Logan for sure has a heart murmur, but it's nothing to worry about. They did find something a little weird though. It is something that is very rare to have. There is an extra vein that is connected to the heart but eventually dissolves (it's either before birth or right after this happens). His did not dissolve. This is not a big deal at all. The doc said that he has a healthy heart and will have a long heart life :). So pretty much Logan has a right and left SVC (superior vena cava) instead of just a right one.
