Amit Raizada Family Helps KU Become First with MediGuide Heart Catheter Gift
Doctors at The University of Kansas Hospital are using new technology for certain cardiac procedures that replicates the cellphone or navigation device on their car dashboards.
Called MediGuide, the technology takes heart catheters fitted with miniature sensors and then uses electromagnetic signals to track the path of the catheter as it moves through a patient’s vein or artery on its way to the heart. To help physicians locate the catheter and make sure it’s on the right path, the signal is superimposed on X-ray, or fluoroscopy, images taken of the patient earlier, essentially creating a map.
The technology, which physicians are likening to the global positioning system satellite network used for navigating cars, boats and planes, is seen as an improvement on the current method, which requires frequent fluoroscopy to track the catheter’s progress. Physicians said the MediGuide exposes the patient to much less radiation during the course of the procedure.
“In traditional intervention procedures, the fluoroscope can be used anywhere from one to four hours to make sure the catheter gets to the correct place,” said Dr. Dhanunjaya Lakkireddy, who leads the complex arrhythmia ablation program at KU Hospital. “With this technology, radiation exposure can be reduced. In our first procedure, exposure went from what would have been about 45 minutes to less than two minutes.”
Although this technology has been used successfully in Israel and Europe, KU Hospital is the first to use it in the United States.
The MediGuide technology, made by Minnesota-based St. Jude Medical Inc., is in the newly created Raizada Family Electrophysiology Lab, part of the Richard and Annette Bloch Heart Rhythm Center.
