Baptist Medical Center in Jackson, Miss. is one of the first hospitals in Mississippi to implement the world’s smallest pacemaker. The procedure was performed in June 2017 by Electrophysiologist James Hamilton, IV, MD, with Baptist Heart.

This was the first procedure of its kind performed in the central Mississippi area. The Micra Transcatheter Pacing System (TPS) is a new type of heart device that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker.

“For patients with indications for single-chamber pacemaker implantation, the Medtronic Micra leadless pacemaker offers a significant leap forward in technology beyond conventional pacemaker therapies allowing for a faster recovery with fewer acute and long-term complications,” said Dr. Hamilton. “The implantation of this leadless device is merely the first step as the field of pacing evolves to replace traditional pacing therapies with multi-component leadless pacemaker systems in the future.”

One of the conditions treated with a traditional pacemaker transplant and now with the Micra Transcatheter Pacing System (TPS) is bradycardia. Bradycardia is a condition characterized by a slow heartbeat, 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 help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.

Physicians at Baptist Medical Center have elected to use Medtronic’s Micra TPS, comparable in size to a large vitamin, 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.

The Micra TPS also 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.

Along with Dr. Hamilton, Electrophysiologist Michael Bensler, MD, performs the procedure too and say patients have done really well.  Dr. Hamilton added, “The electrophysiology team of physicians and staff at Baptist Heart remain committed to offering the most advanced therapies available for cardiac rhythm abnormalities.”

The Micra TPS is 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.
