“…Our present understanding of LP retrieval is derived from results of limited animal studies and human data. [51][52][53][54] The retrieval procedure for the Nanostim LP has been standardized. A dedicated retrieval catheter and snare system is advanced via the femoral vein to the RV.…”

“…When the snare grasps the docking button of the pacemaker, the protective sleeve is advanced halfway over the device. 54 The retrieval catheter is then aligned with the device and rotated counterclockwise to unscrew its helix. 54 In contrast, retrieval of the Micra LP is more variable.…”

Leadless pacing is a major breakthrough in the management of bradyarrhythmia. Results of initial clinical trials that have demonstrated a significant reduction in acute and long‐term pacing‐related complications have been confirmed by real‐world experience in a broader spectrum of patients. Nonetheless current use of a leadless pacemaker is hampered by its limited atrial sensing and pacing capability, as well as battery life‐span and retrievability. We review the current clinical outcome data, indications and contraindications, implantation and retrieval techniques, synchronous ventricular pacing, and other clinical considerations. We also provide an overview of the latest advancements in leadless pacing technology including device‐to‐device communication and energy harvesting technology.

“…Most experience has been gained by retrievals of the Nanostim LCP due to the medical device advisory on battery failure 20,52,53 . The most common reasons for retrieval were need for a device upgrade to an Cardiac resynchronization therapy ‐ Defibrillator (ICD/CRT‐D) and battery failure for Nanostim and VHPTs/loss of capture for Micra 49 .…”

“…The most common reasons for retrieval were need for a device upgrade to an Cardiac resynchronization therapy ‐ Defibrillator (ICD/CRT‐D) and battery failure for Nanostim and VHPTs/loss of capture for Micra 49 . In a recent comparative study, 53 while 50% of Micra TPS retrievals were early with a median time to extraction of 46 days, 100% of Nanostim LP retrievals were late: they had a median time to extraction of 256 days and a maximum of 4 years. Difference in retrieval success rates appeared to favor Micra over Nanostim (100% vs 90%, P = .049), even if direct comparison is not appropriate due to the significant differences in time to extraction.…”

Theleadless pacemaker (LLPM) therapy has been developed in recent years to overcome the transvenous lead and device pocket‐related complications. The LLPMs now available are self‐contained right ventricular pacemakers and are limited to single‐chamber ventricular pacing modality. This literature review deals with the current status of LLPM technology and current areas of clinical applicability. The safety and efficacy outcomes published from randomized clinical trials and real world registries are analyzed and compared with historical conventional transvenous pacemaker data. Furthermore, new pacing modalities and future perspectives to broaden the clinical use and cover most of pacing indications are discussed. Due to the overall safe and effective profile in the short term and intermediate term, also in fragile patients, the LLPM use is constantly growing in daily clinical practice. Actually, it can be considered a landmark innovation, through which a new era of cardiac pacing has begun.

Since the introduction of transvenous cardiac pacing leads, pacemaker system design has remained similar for several decades. Progressive miniaturisation of electronic circuitry and batteries has enabled a smaller, single pacing unit comprising the intracardiac electrodes, generator and computer. This review explores the development of leadless pacing, the clinical trials comparing leadless to transvenous pacing in addition to the future developments of multichamber leadless pacing.
