I just got a call from them.

The heart specialist did look at him, and his heart is a little larger than it should be. He needs a ultrasound or something to see what is going on. (An extra $200+) She said it is important to have it done so they know what's going on with him, especially if he has another blockage. For now, he can't eat that special food as it may be bad for his heart.

On the plus side, he has been peeing just fine all day today and gets to come home in an hour! I'm frightened to see the bill though I already gave them 450, and they said it would be atleast 700. The girl just said it was like 300 to do whatever tests they did to his heart?? Ick...Plus another 200 for the ultrasound he needs. This is why he can't get it again because I won't be able to help him next time.
