Key result
Protective sleeve encapsulation enables safe bailout retrieval of tissue-entrapped atrial leadless pacemakers.
Why the study?
Complications such as myocardial entrapment during repositioning of active-fixation atrial leadless pacemakers pose challenges for safe retrieval techniques.
Case Report (n=1)
Advancing the protective sleeve to fully encapsulate an active-fixation atrial leadless pacemaker may serve as an effective bailout technique for safe retrieval during myocardial entrapment.
Myocardial entrapment during AVEIR AR repositioning warrants procedural caution in complex patients; this single case leaves optimal rescue techniques open for further study.
An 81‐year‐old woman with a medical history of mechanical mitral valve replacement, Maze procedure, and multiple myeloma presented with symptomatic sinus arrest and underwent AVEIR DR implantation. Although the AVEIR VR was successfully implanted, optimal electrical parameters could not be achieved during AVEIR AR placement. During repositioning of the AVEIR AR, myocardial entrapment with helix stretching was encountered. Here, we report that advancing the protective sleeve to fully encapsulate the device potentially enabled safe and successful retrieval.

Yoshida et al. (2026) conducted a case report in Symptomatic sinus arrest with myocardial entrapment of atrial leadless pacemaker (n=1). Advancing the protective sleeve to fully encapsulate the device was evaluated on Safe and successful retrieval of the device. Advancing the protective sleeve to fully encapsulate the device enabled safe and successful bailout retrieval of a tissue-entrapped active-fixation atrial leadless pacemaker.
