My 6 year old Maddie has bee diagnosis with Base heart tumor/also know as Myocrdial tumor. I have done some googling and all info is several years old. does anyone know anything new about this. I do know it is non operable. and that we may not have long with her . they say she is not in pain. she also is being treated for arrhythmia . we took her in sat evening because her stomach was big they did ekg, ultra sound, and xrays. drew fluid from stomach to find it was not blood.
