Just a nervous mom here! Our 18year old son was just was (3 days ago) told he's now in the severe status...51 pressure gradient and heart wall thickness is 14. When he experiences any symptoms, it's time for surgery. We've been preparing for this for 4 years. He seems to be handling it ok. We were basically told that baseball, now in his senior year is out. He's thinking about golf now. I'm just paranoid that we won't know when it is time...that we'll shrug off slight symptoms. I know about a week ago he got up quick from the couch and had to stop because he got light headed. We'll, that happens to me on occasion too. I feel terrible now that I didn't tell the cardio. About that, although at the time, I didn't even think about it. You know, at the time you don't think much of it. I guess I won't be doing that anymore.
