(KMOV)-- A Shrewsbury woman is one of the first in the St. Louis area to get a newly-designed pacemaker. Mary Allen, 85, had the surgery Friday morning.
What's new and different about this pacemaker is it allows patients to get an MRI scan.
Right now 200,000 patients a year can't get an MRI because it would interfere the pacemaker in their chest.
"For pacemakers I think this is the biggest advancement we've had in several decades. Even in the 80s from the 80s til now, pacemaker technology hasn't changed very much," said Dr. Brian Seeck of the SSM Heart Institute.
Dr. Seeck said at some point the MRI friendly pacemaker is going to become the standard for doctors and their patients.
