Is this trial a fit for you?

Likely a good fit

Adults (18+) with at least one standard pacemaker indication who are willing to participate in all follow-up visits and provide informed consent.

Probably not a fit

Patients who do not require cardiac pacing or those with conditions that contraindicate the implanted system may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-arm feasibility study evaluating the AVEIR Conduction System Pacing Leadless Pacemaker in patients with standard pacing indications. Participants will be followed from the implant through multiple post-procedure visits over at least a year, with data collection at baseline, during implantation, and at 1, 2, 3, 6, and 12 months and then every six months. The aim is to assess chronic safety and performance of the leadless system in real-world use. The study does not include randomization or blinding and focuses on feasibility in a specific patient population. Data will inform long-term outcomes and potential broader use of this technology.

Why it matters

Potential benefit: If successful, the leadless pacemaker could reduce complications related to leads and pockets and provide reliable pacing for patients with bradycardia.

How similar studies have gone: Prior studies of leadless and conduction-system pacing approaches have shown feasibility; this study specifically assesses chronic safety and performance in a single-arm design.
