We report the first‐in‐human retrieval of a chronically implanted Micra transcatheter pacing system (TPS; Medtronic, Minneapolis, MN, USA). A 41‐year‐old woman suffering from third‐degree atrioventricular block was successfully implanted with a TPS in the low septum of the right ventricle. After 29 months, due to an increased electrical threshold and 100% pacing percentage, the device showed low battery voltage. Despite the long implant duration, the attempt of device retrieval using a snare loop inserted in the delivery system of a TPS was successful. In the same procedure, a new leadless pacemaker was implanted in the high right ventricular septum with optimal pacing threshold.
