The first implantation of an MRI-compatible pacemaker in Michigan was performed Wednesday at Spectrum Health Fred and Lena Meijer Heart Center. The device allows patients with a pacemaker to undergo safe magnetic resonance imaging scans.
An 80-year-old man received a Revo MRI SureScan pacing system, the first MRI-conditional pacing system designed, tested and FDA-approved for use in an MRI environment.
Prior to this system, MRI procedures for patients with implanted pacemakers were not recommended because they might cause serious complications, such as interference with pacemaker operation, damage to system components and wire or pacemaker dislodgement.
“Medical imaging and electronic implantable devices such as pacemakers are important technological advances, particularly with our older patients,” said electrophysiologist Andre Gauri, MD, of West Michigan Heart. “We encourage people to talk to their doctor about which pacing system is right for them.”
The number of patients with pacemakers is growing at the same time that the use of MRI is increasing. About 40 million MRI scans are performed annually in the United States and Spectrum Health Butterworth and Blodgett hospitals perform approximately 18,000 to 20,000 MRI scans each year. Physicians often prefer MRI because it provides a level of detail and clarity not offered by other soft tissue imaging modalities.
Research indicates that there is a 50 percent to 75 percent probability that cardiac device patients will need an MRI over the lifetime of their device. Additionally, more than 200,000 patients annually in the U.S. have to forego an MRI scan because they have a pacemaker. The new pacing system a Meijer Heart Center will help address this patient need.
Developed by Medtronic, the Revo MRI SureScan pacing system is the first pacing system of its kind in the U.S. It was designed to address safety concerns around MRI procedures for patients who have implanted pacemakers. MRI scanners may cause traditional pacemakers to misinterpret MRI-generated electrical noise and withhold pacing therapy or deliver unnecessary pacing therapy. This new pacing system, when programmed into a special mode prior to an MRI scan, can be used safely in the MRI environment.
