The Lead Episode 129: A Discussion of Worldwide Chronic Retrieval Experience of the Helix Fixation Leadless Cardiac Pacemaker

Join Tina Baykaner, MD, MPH, HRS Digital Education Committee Vice-Chair, and her guests Mikhael F. El-Chami, MD, FHRS and  Devi G. Nair, MD, FHRS for this week’s Lead episode.

This article summarizes the worldwide experience retrieving chronically implanted active helix-fixation leadless ventricular pacemakers (the Aveir/Abbott platform) across regulatory clinical trials. The authors assess real-world feasibility, procedural techniques, success rates, and complications of retrieval after long dwell times, demonstrating that devices can be removed safely and effectively even years after implant—up to about 9 years in follow-up. Overall, chronic retrieval success remained high with a low rate of serious adverse events, supporting helix-fixation leadless systems as a manageable long-term pacing strategy when replacement or removal is needed.

Learning Objectives

• Explain the clinical indications for chronic retrieval of helix-fixation leadless pacemakers and how these differ from tine-fixation platforms.

• Summarize the reported worldwide chronic retrieval success rates, implant-duration range, and key procedural or anatomic reasons for retrieval failure.

• Identify practical procedural considerations (e.g., docking-button access, retrieval catheter use, imaging support) that improve the likelihood of safe long-term leadless pacemaker removal.
