Reading https://www.cardiovascular.abbott/us/en/hcp/products/cardiac-rhythm-management/pacemakers/aveir-vr-leadless-pacemaker/how-it-works.html they talk a lot about retrieval and claim "The Aveir VR Leadless Pacemaker's predicate device has a chronic retrieval success rate above 80% with helix fixation through 7 years, regardless of implant duration." - that's a little too jargony for me to confidently unpack, but it at least sounds like they'll try to take it out.
