Key result
Double-snare technique successfully retrieves a dislodged AVEIR leadless pacemaker from the right pulmonary artery.
Why the study?
Leadless pacemakers are effective alternatives to traditional transvenous pacemakers, but detachment and displacement are serious complications.
Case Report (n=1)
No
This case demonstrates that an acutely dislodged AVEIR leadless pacemaker migrating to the pulmonary artery can be successfully retrieved and redeployed using a double-snare technique.
Does not support practice change; leaves open need for prospective data on retrieval techniques.
BACKGROUND: Leadless pacemakers (LPs) are safer and more effective alternatives to traditional transvenous pacemakers, but LP detachment and displacement are serious complications. CASE PRESENTATION: We report a case of AVEIR LP implantation, immediate dislodgement into the right pulmonary artery, and retrieval in an 82-year-old woman. CONCLUSION: The device was retrieved successfully using a gooseneck snare and the tri-loop snare of the retrieval catheter, then re-implanted.

Song et al. (2026) conducted a case report in Atrial fibrillation and transient asystole (n=1). AVEIR leadless pacemaker implantation and snare retrieval was evaluated on Device retrieval and re-implantation success. A dislodged AVEIR leadless pacemaker in the right pulmonary artery was successfully retrieved using a gooseneck and tri-loop snare technique and re-implanted without complications.
