Fluoroscopic Views of Leadless Pacemaker Retrieval

(A) The system’s distal cone is positioned at the proximal aspect of the device. After snare advancement, the catheter is deployed around the proximal retrieval feature of the Micra transcatheter pacing system (TPS). (B) The snare is engaged and locked around the retrieval feature the Micra TPS. (C and D) After engaging the snare, the distal cone is docked and crossed over the Micra TPS. (E) Tension on the snare along with countertraction from the distal cone results in the release of the tines from the myocardium, and the Micra TPS is withdrawn from the patient’s body. (F) Reimplantation of a new Micra TPS is performed immediately after retrieval. ∗Left ventricular electrode of WiSE (EBR Systems, Sunnyvale, California); †transmitter; §battery pack.
