Why the study?
The safety, feasibility, and ability to retrieve and replace a chronically implanted leadless pacemaker specifically with anchor/tines fixation remain an unanswered clinical question.
Is it safe and feasible to retrieve and replace a 7-year-old implanted leadless pacemaker with tines fixation?
Is it safe and feasible to retrieve and replace a 7-year-old implanted leadless pacemaker with tines fixation?
This report addresses the feasibility and safety of retrieving and replacing a 7-year-old implanted leadless pacemaker with tines fixation, an area with no prior studies.
Retrieval feasible at 7 years in select cases; leaves open generalizability and long-term safety.
The Micra transcatheter pacing system (TPS) (Medtronic, Minneapolis, MN, USA) is a clinically effective alternative to transvenous pacemakers for single-chamber ventricular pacing (1). Although abandonment of the TPS at the end of life is recommended, retrievability is one of the critical management strategies in specific scenarios (2). There are no studies pertaining to the safety and feasibility of retrieving and replacing a chronically implanted Micra TPS (3). Despite already published results, the ability to retrieve or remove chronically implanted LP specifically with the anchor fixation type is an unanswered important aspect of this device management (4, 5).
