MidMichigan Offers Patients New Miniature Leadless Pacemaker Option
MidMichigan’s Heart and Vascular Program is now offering a new miniature leadless pacemaker implant for qualified patients with permanent atrial fibrillation. The Micra™ Transcatheter Pacing System, developed by Medtronic, is specifically designed for patients who have been diagnosed with bradycardia, a too-slow heart rhythm. The device is more than 90 percent smaller than a traditional transvenous pacemaker and is completely self-contained within the heart.

“This miniature pacemaker device is a self-contained generator and electrode system which we implant directly into the patient’s right ventricle using a femoral vein transcatheter approach,” said Electrophysiologist Nilofar Islam, M.D. “This minimally-invasive procedure requires no chest incision and the pacemaker is leadless, which also reduces complications. With transvenous pacemakers, which have thin wires called leads, pocket infections, hematomas, lead dislodgment and lead fractures can occur.”
Because the device is implanted using a catheter and is completely self-contained within the heart, the patient has no chest scar and there no visible bump or physical reminder of a pacemaker under the skin. This also results in fewer post-implant activity restrictions.
According to Dr. Islam, leadless pacemakers are not appropriate for all atrial fibrillation patients. “This device is designed for patients with permanent atrial fibrillation with bradycardia,” she added. “Those with sick sinus syndrome, also known as sinus node disease or sinus node dysfunction, are not currently candidates. We are very pleased to bring this state-of-the art technology to central and northern Michigan.”
