Implantation techniques for a helix-fixation dual-chamber leadless pacemaker

Dual-Chamber Leadless Implant Procedure. In a pivotal trial (NCT05252702), the AVEIR™ DR (Abbott) leadless pacemaker system was found to be safe and effective in delivering DDDR synchronous atrial and ventricular pacing. This dual-chamber system employs 2 leadless pacemakers with implant-to-implant (i2i) communication. Although implantation of the ventricular device as a single-chamber pacemaker has been well described, there are additional considerations surrounding the dual-chamber implant procedure. Herein, we review the dual-chamber leadless pacemaker implant workflow, while providing guidance to optimize safe and effective implant procedures.
