Official title: Leadless Pacemaker Registry

Run by Karl Landsteiner University of Health Sciences · NCT07246135 · Data updated 2026-11-12

This registry will collect and analyze outcomes and complications in adults who receive leadless pacemakers at University Hospital St. Pölten to see how the devices perform over time.

Is this trial a fit for you?

Likely a good fit

Adults (age ≥18) who receive or previously received a leadless pacemaker at University Hospital St. Pölten and can provide written informed consent are eligible.

Probably not a fit

Patients with conventional transvenous pacemakers, those treated outside University Hospital St. Pölten, or individuals unable or unwilling to give informed consent are unlikely to benefit from participation.

What this trial studies

This single-center registry prospectively and retrospectively collects data on all leadless pacemaker implantations performed at University Hospital St. Pölten, including demographic information, implantation indications, procedural details, and follow-up findings. Data from patients implanted since 2015 (retrospective inclusion) and from new implantations (prospective inclusion) will be captured, and patients will be invited to participate at routine clinic visits. The registry will record acute, medium-, and long-term complications and will include analysis of novel atrial mechanical sensing markers for which long-term experience is limited. No investigational interventions are performed as part of the registry; it is observational and based on routine clinical care and follow-up visits.

Why it matters

Potential benefit: If successful, the registry could clarify safety, complication rates, and long-term performance of leadless pacemakers and help clinicians optimize device selection and follow-up care.

How similar studies have gone: Previous registries and device studies have shown generally favorable short- and mid-term safety and performance of leadless pacemakers, but aspects like atrial mechanical sensing remain relatively novel and lack long-term data.
