St. Joseph Mercy Ann Arbor first in southeast Michigan to implant new single- and dual-chamber pacemakers FDA-approved for MRI scan
Start Date
ANN ARBOR, Mich. – (August 21, 2014) – Doctors at St. Joseph Mercy Ann Arbor have completed the first implant of a pacemaker system that is FDA-approved for use with MRI (magnetic resonance imaging) scans, under certain restrictions. The device, the Entovis ProMRI® pacing system developed by BIOTRONIK, is one of the first pacemakers in the U.S. with MR-conditional labeling, meaning that it has been demonstrated to pose no hazards when used in an MRI environment under specified conditions of use.

Several million patients are currently implanted with pacemaker systems worldwide. Recent studies show that many of them will develop a clinical need for an MRI scan during their lifetimes. MRIs serve as a primary diagnostic tool for many diseases and conditions and have several advantages over other diagnostic procedures. For instance, patients who have chronic atrial fibrillation and have suffered a stroke or have lost consciousness, fallen and suffered moderate to severe injuries like hip fractures and head trauma, benefit from an MRI scan.

“MRI is critical in the diagnosis of many serious conditions but, until now, patients with traditional pacemakers have been denied access to this important imaging tool,” said Dr. Timothy Shinn, director of the electrophysiology department, St. Joseph Mercy Ann Arbor. “Now, with our MR-conditional pacemaker we have the ability to detect health issues that may otherwise be difficult to diagnose. The Entovis ProMRI® device allows us to give our patients the treatment they need for existing heart conditions with the peace of mind that they will be able to receive diagnostic scans in the future, if needed.”

BIOTRONIK ProMRI® device and lead systems increase the potential to improve patient access to MRI scanning for those who require pacemakers and give physicians more options to choose from without any compromise on the therapy. The Entovis ProMRI® device offers daily monitoring through BIOTRONIK’s Home Monitoring technology and provides the most advanced physiological therapy available.

This procedure was made available at St. Joseph Mercy Ann Arbor through the research department at Michigan Heart.
