Retrieval and replacement feasibility of 7-year-old implanted leadless pacemaker with tines fixation

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).
