If your child is scheduled to have an echocardiogram (echo) prior to his or her office visit, please consider the following helpful tips:
If your child’s echocardiogram is completed outside of our office or Mercy Medical Center, please bring a copy of the echocardiogram to your child’s appointment. Chest X-rays, when needed, must be completed two days before the scheduled appointment. If the X-ray is not completed by Mercy Medical Center, RCI or UnityPoint, please bring the X-ray with you to your child’s appointment.
If you are unable to complete the chest X-ray two days prior to the appointment, please call (319) 398-6650 to reschedule. We cannot see your child without access to a completed chest X-ray.
To make the best use of your time when you are here, we ask that you consider the following polices in advance of your visit:
You will receive a reminder phone call prior to the scheduled appointment.
If you have a concern about your child’s cardiac condition after hours, please call (319) 398-6650. If your child is having a non-cardiac issue, please contact your family physician or pediatrician.

Hayley and her husband, Eric, noticed Carter's head bobbed slightly with each breath and his chest retracted in unusual places. Read their story on page 6.
