Key result
Aveir extraction tool successfully removes a ~5.5-year-old Micra AV pacemaker without complications.
Why the study?
Tine-based leadless pacemakers have been implanted for over 10 years, but retrieval of older devices is rarely discussed and limited to rare case reports.
Can an older (5.5-year) Micra AV leadless pacemaker be safely extracted using the Aveir retrieval device?

Can an older (5.5-year) Micra AV leadless pacemaker be safely extracted using the Aveir retrieval device?
This case demonstrates the feasibility and safety of extracting an older (5.5-year) Micra leadless pacemaker using the Aveir retrieval device.
Single-case Micra AV extraction success is hypothesis-generating; prospective data needed before broader adoption.
BACKGROUND: Tine-based leadless pacemakers have been commercially implanted over the last 10 years. Retrieval of older devices is rarely discussed and based on rare case reports only. METHODS: A retrospective review of an extraction case of a Micra AV leadless pacemaker was performed. Internal Review Board approval was obtained. RESULTS: After successful lead extraction and implant of Aveir leadless device in a 44-year-old female, retrieval of a 5.5-year-old Micra AV was performed using the Aveir extraction tool, under transesophageal echocardiogram guidance. No complications occurred. CONCLUSIONS: Successful, safe extraction of a 5.5-year-old Micra leadless device can be performed with the Aveir retrieval device after immediate lead extraction.

Messele et al. (2026) conducted a case report in Leadless pacemaker extraction (n=1). Aveir extraction tool was evaluated on Complications. Extraction of a 5.5-year-old Micra AV leadless pacemaker using the Aveir extraction tool was performed successfully with no complications in a 44-year-old female.
