Remote monitoring of leadless pacemakers using a novel conductive telemetry communication method

Remote care has become part of the standard of care for cardiac rhythm device management. The Aveir™ single-chamber (AR and VR) and dual-chamber (DR) leadless pacemaker (LP) systems (Abbott, Abbott Park, IL) utilize a novel conductive telemetry communication schema for device interrogation and programming. A patient transmitter is designed as an at-home remote monitoring solution that interrogates the Aveir leadless pacemaker system via conductive telemetry and transmits the patient data.

To characterize the performance of a remote care system that interrogates implanted Aveir LP systems via conductive telemetry.

Patients implanted with an Aveir DR, VR, or AR system were enrolled in a data collection study upon hospital IRB approval of the study. The study protocol included (1) in-clinic interrogation of the LP system using the patient transmitter in a controlled setting, in two modes of use (hand-held and wired modes); and (2) optional at-home interrogation using the patient transmitter.

Thirty-one (25 males/6 females) subjects in three centers completed in-clinic interrogation of their Aveir system using the patient transmitter in both modes of use. Eighteen subjects completed at-home interrogation. Transmitter performance was comparable between modes of use, and between in-clinic and at-home interrogation. In all subjects 31/31 (100%), end-to-end remote care system use was successful.

The initial, real-world experience of utilizing an end-to-end remote care system with Aveir LP patients demonstrated feasibility of this technology to offer an at-home remote monitoring solution for leadless pacemaker patients via conductive telemetry (Funded by Abbott Laboratories; Clinical Trials.gov ID:NCT06542133).
