My 4 1/2 yo grandson had Tetralogy of Fallot repair at age 6 months. Yesterday he threw up what looked to be all of his stomach contents. He does this at preschool and at Sunday school, too. It seems to happen most often after he s eaten. I m thinking he has to slow down, calm himself before eating anything but he can also throw up when getting too energetic after eating. Am concerned that this is heart-related. He did not require a valve replacement. His surgery was done by Dr. Teodori at Phoenix Children s hospital and he is well respected. There is no follow up visit scheduled until May of next year...should we pursue an appointment before that time?
