The electrophysiology team at Norton Heart & Vascular Institute has implanted the city’s first dual chamber leadless pacemaker. What makes this device unique is its size, absence of leads that connect the device to a controller and ability to implant it with a minimally invasive procedure. 

The Aveir DR consists of two leadless pacemakers that are implanted into the upper and lower chambers of the heart. The two pacemakers communicate with each other based on the person’s needs to more effectively regulate heart rhythm. 

“A leadless pacemaker is unique technology that was only available for limited types of patients in the past,” said Sofya Kuznetsov, M.D., electrophysiologist, Norton Heart & Vascular Institute Heart Rhythm Center. “The ability to pace upper and lower chambers in sync was only available with conventional transvenous devices.

“The leadless pacemakers are smaller than an AAA battery and can communicate wirelessly with each other to control the heart’s rhythm. They do not require a surgical incision and avoid potential complications associated with conventional pacemaker leads, such as infection or lead fractures. An additional benefit is quicker recovery and fewer mobility restrictions after the procedure.”

Until now, leadless pacemakers have not allowed a dual chamber option, which is needed by nearly 80% of people needing this kind of treatment.
