New Technology At The Nicklaus Children’s Hospital


Nicklaus Children’s Hospital is the second children’s health facility in the world to use new medical technology in cardiac procedures that is similar to global positioning systems (GPS) that drivers use to determine the location of their vehicles on a map. The new equipment is part of the hospital’s modern, state-of-the-art cardiac catheterization lab, in which minimally invasive catheter-based procedures are performed to treat children with congenital heart defects.

The MediGuide Technology permits doctors to see the precise location of specially designed delivery tools and catheters set up with miniature sensors to navigate within the heart. Using a low-powered electromagnetic field, the system permits the doctors to see in real-time, a three-dimensional image of these tools on a pre-recorded fluoroscopy (rapid series of X-ray images). Automatic adjustments are made to the pre-recorded images to compensate for changing heart rhythms, breathing, and patient movement. By allowing the doctors to track devices on pre-recorded fluoroscopy, MediGuide technology can help avoid additional fluoroscopy throughout the procedure, which in turn dramatically cuts down radiation exposure.

Dr. John Rhodes, medical director of cardiology stated, “The longstanding commitment of The Heart Program at Nicklaus Children’s is to minimize the cumulative impact on the children in our care. The MediGuide Technology supports us in this effort by reducing exposure to radiation during procedures and enhancing patient safety. It reflects our commitment to investing in the latest technology to ensure the best possible outcomes and safest practices for the children we serve.”

The MediGuide Technology may be used to help a doctor in navigating delivery tools and catheters in the cardiac anatomy during implantable device procedures, such as cardiac resynchronization therapy (CRT) cases, which helps restore a patient’s heart rhythm back to normal and protects against sudden cardiac death for CRT device patients. MediGuide Technology also can be used in ablation procedures where radiofrequency energy is delivered to correct an arrhythmia.
