Presence Resurrection Medical Center Now Offers the World’s Smallest Pacemaker

Miniaturized Heart Device Provides the Most Advanced Pacing Technology Available

(CHICAGO, IL, Sept. 5, 2018) – Presence Resurrection Medical Center today announced that it is one of the first hospitals in Illinois to offer the world’s smallest pacemaker for patients with bradycardia. The Micra® Transcatheter Pacing System (TPS) is a new type of heart device, approved for Medicare reimbursement, which provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker. The first procedure at Presence Resurrection Medical Center was performed by cardiac electrophysiologist, Erica Engelstein, M.D. on September 4, 2018.

Bradycardia is a condition characterized by a slow or irregular heart rhythm, usually fewer than 60 beats per minute. At this rate, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells. Pacemakers are the most common way to treat bradycardia to help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.

Comparable in size to a large vitamin, physicians at Presence Resurrection Medical Center have elected to use Medtronic’s Micra TPS because unlike traditional pacemakers, the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy. Instead, the device is small enough to be delivered through a catheter and implanted directly into the heart with small tines, providing a safe alternative to conventional pacemakers without the complications associated with leads – all while being cosmetically invisible. The Micra TPS is also designed to automatically adjust pacing therapy based on a patient’s activity levels.

“We are excited about being able to offer the world’s smallest pacemaker to our patients. Among the advantages of this technology are the lower risk of infection and lower risk of complications due to having leads within the blood vessels and heart” said Dr. Erica Engelstein. “Also, patients are able to resume their usual activities without restrictions within a few hours after the procedure.” 

The Micra TPS incorporates a retrieval feature to enable retrieval of the device when possible; however, the device is designed to be left in the body.  For patients who need more than one heart device, the miniaturized Micra TPS was designed with a unique feature that enables it to be permanently turned off so it can remain in the body and a new device can be implanted without risk of electrical interaction. It is also the first and only transcatheter pacing system to be approved for both 1.5 and 3 Tesla (T) full-body magnetic resonance imaging (MRI) scans and is designed to allow patients to be followed by their physicians and send data remotely via the Medtronic CareLink® Network.

Approved by the U.S. Food and Drug Administration in April 2016, the Micra TPS has been granted Medicare reimbursement, allowing broad patient access to the novel pacing technology.
