摘要

Background

The Dual chamber leadless pacemaker (DC-LP, Aveir DR) system introduces a pivotal innovation in pacing by enabling dual-chamber synchronization in a completely self-contained system.

Methods

This was a retrospective, single-center study that included consecutive 102 patients who underwent implantation of the dual-chamber leadless pacemaker system at Staten Island University Hospital between January 2024 and February 2025. Procedural and electrical outcomes were assessed at implant, 1–3 months and 3–6 months follow-up.

Results

The study cohort included 102 patients with a mean age of 77.3 ± 10 years, and a male predominance (57.8%). The most common indication was sinus node dysfunction (48.0%). All 102 patients underwent successful implantation of both atrial and ventricular devices. There were 2 device dislodgements after deployment (1 intra-procedural and 1 post-procedural). No other major complications were noted. Electrical parameters and device communications remained consistent and favorable throughout follow-up.

Conclusions

Dual chamber leadless pacemaker system provides a high rate of procedural success and maintains reliable short-term electrical performance in both atrial and ventricular components. Further large-scale, prospective studies with extended follow-up and comparative arms are needed to assess the long-term performance, clinical benefits, and economic viability of this novel pacing system.

What’s new

• This study stands out as one of the first independent and large-scale, single-center investigations on ‘real-world’ experience of consecutive cases, confirming previously published results.

• Additionally, our study had a robust follow-up looking at the data of individual patients in much detailed granularity.

• This study corroborated that dual-chamber leadless pacing achieves high implantation success rate and stable short-term function in both chambers.
