My son had an ECHO test performed three weeks a go due to an emergency hospital trip. The trip was totally unrelated to his heart but they ran an ECHO just to be sure and by chance they found something abnormal. We drove three hours yesterday to a "specialist" who could only tell me that a part of his aorta is bubbled out. She said his aorta is normal size and then extends out a little then goes back to normal. She said "I don't know what it is" I asked her several questions and she said "I don't know" or "I can't be sure." She said he will either grow into it, it could be just a different style of development, or that it could get bigger. She didn't offer to do another echo test until three months from now. I'm nervous to wait that long. I AM going to ask his pediatrician to refer me to someone else for a second opinion and to run another Echo. To me this sounds like an aneurysm, but being a cardiologist wouldn't she know this? She never mentioned the word aneurysm to me, then again she was not compassionate at all. Have you ever heard of a condition where the aorta is normal size then dilates out then goes back to normal? He is 14 months old. Also, if the second opinion I receives does say it is an aneurysm, are aneurysms common i young children? How long do they take to grow and burst? Thanks ahead of time!
