Wow, sorry but that's a little scary to me. At ages of adolescence, the sludge in the arteries is not like that of an adult(hardened)So I think I would look at a second opinion. I had surgery in January at UCLA, with Dr. Erik Dutson & Dr JC JImenez. In Chicago, try Chicagos' s Comer Hospital, look at contacting Christopher Speaker, he is the surgery coordinator there, he has Lots of informatiuon & it is a childrens hospital. Good Luck!!
