Micra TM (Medtronic Inc) transcatheter pacing system (TPS) is a leadless pacemaker with a nitinol tine-based fixation mechanism. Growing scientific evidences seem to confirm safety and effectiveness in acute and mid-term settings. 1 While TPS implantation, requiring a specialized skill set, is a well-established step by step procedure, far most challenging seems to be TPS retrieval, after cutting the tether. 2 In addition to the fact that there is no specialized system for TPS retrieval, there

During the first implant the TPS was deployed to the interventricular mid-septum and successfully recaptured for three times, due to unsatisfying pacing thresholds (2 V/0.24 ms), until final mid-septal position under the septomarginalis trabeculation was achieved with Published on behalf of the
