Revolutionary Pacemaker Lessens Patient Complications

Written by W. Michael Kutayli, MD

Micra™ is the newest and smallest pacemaker, approved for use in the United States by the FDA in April 2016. Bryan Heart is the first in Nebraska to offer this true revolution in pacing technology.

Benefits of Micra:

  • 93% smaller than conventional pacemakers, about the size of a large vitamin capsule 
  • Micra is implanted directly into the patient’s right ventricle 
  • Micra is self-contained within the heart
  • Its small size is a giant leap forward for patients requiring single chamber ventricular pacing 
  • Improved patient experience – no chest scar, no bump, no visible or physical reminder of a pacemaker under the skin and fewer post-implant activity restrictions 

Eliminates complications of traditional pacemakers:

  • Infection
  • Hematoma 
  • Erosion

Eliminates lead-related complications of traditional pacemaker complications:

  • Fractures
  • Insulation breaches
  • Venous thrombosis and obstruction
  • Tricuspid regurgitation

The Pacemaker’s Past

Cardiac pacemakers were developed in the 1950s primarily to treat life-threatening transient heart blocks after cardiac surgery. These pacemakers were large external devices connected to epicardial electrodes placed surgically. Although life-sustaining, these pacemakers were plagued by many problems including short battery life, failures in delivering energy to the heart muscle through wires called leads and infections, due in part to externalization of part of the system.

Pacemaker Technology Improvements

Improvements in pacing technology over the past five decades have been incremental, but some advances have certainly been game-changing; including dual-chamber pacing to allow maintenance of atrioventricular synchrony, rate responsive pacing and cardiac resynchronization therapy, with or without defibrillation backup.

Despite these developments, certain persistent problems inherent to the implantation and management of pacemaker systems including transvenous leads - a device placed in the patient’s chest with leads running to the heart - remain.  

Until now.
