AVEIR™ Leadless Pacemaker (LP) United Kingdom (UK) Registry

Not yet recruiting

• Conditions: Bradycardia; Atrio-Ventricular Block; Syncope

• Registration Number: NCT06854484
• Lead Sponsor: Royal Brompton & Harefield NHS Foundation Trust

Brief Summary

This observational study will follow patients requiring implantation of leadless pacemaker for 5 years after implantation. The main goal is to evaluate the long term safety and efficacy of AVEIR™ leadless pacemaker device in the usual clinical settings within the UK National Health Service. In addition, the study will collect data to understand patient characteristics receiving this type of pacemaker.

Detailed Description

AVEIR™ stimulator (Abbott) obtained the approvals in July 2023 and started to be implanted in patients in Europe. As a leadless pacemaker, the AVEIR™ Leadless Pacemaker (LP) does not need a connector, pacing lead, or pulse generator pocket. The LP is delivered percutaneously via the femoral vein through an AVEIR™ Introducer and Delivery Catheter. AVEIR™ LP is intended to provide bradycardia pacing as a pulse generator with built-in battery and electrodes for implantation. The LP is intended to provide sensing of intrinsic cardiac signals and delivery of cardiac pacing therapy to the target treatment group.

The purpose of this study is to understand long term safety and performance characteristic of this device. In addition, the study will collect anonymous clinical data and characteristics of the patients chosen to be implanted with AVEIR™ leadless pacemaker in routine clinical practice in approved centres across the UK.

Six hundred patients will be recruited in up to 15 centres during 2 years recruitment period. They will be followed up for 5 years after implantation of the leadless pacemaker. Investigators will record their age, sex, medical history, indications for receiving AVEIR™ and any complications related to the implantation procedure or the device itself. All the data will be collected in an anonymous format. Patients will be followed up according to the standard of care in the national health care system.

Primary Outcome Measures

Name	Time	Method
Percentage of patients without complications related to the device or implantation procedure.	5 years	Complications arising from the procedure or the device will be recorded to evaluate the success rate of the implantation.
Percentage of patients requiring re-intervention.	5 years	Replacement, explant, upgrade, or modification of the position of the device are considered re-interventions which will be used to evaluate safety of the device.
