Jordan S Leyton-Mange, Theofanie Mela
Cardiac resynchronization therapy has emerged as the gold standard for heart failure patients with left ventricular systolic dysfunction and electrical dyssynchrony from an intrinsic intraventricular conduction delay or right ventricular pacing. However, the limits imposed by the coronary sinus venous anatomy restrict the applicability of the technology for many potential recipients. Furthermore, conventional resynchronization, by virtue of utilizing a single site of epicardial origin for left ventricular activation, is non-physiological...

Pacemakers have existed for decades as a means to restore cardiac electrical rhythms. However, lead-related complications have remained a clinical challenge. While market-released leadless devices have addressed some of the issues, their pacer-integrated batteries cause new health risks and functional limitations. Inductive power transfer enables wireless powering of bioelectronic devices; however, Specific Absorption Rate and size limitations reduce power efficiency for biomedical applications. We designed a remote-controlled system in which power requirements were significantly reduced via intermittent power transfer to control stimulation intervals...

BACKGROUND: Early experience with leadless pacemakers has shown a low rate of complications. However, little is known about system revision in patients with these devices. OBJECTIVE: To describe the system revision experience with the Micra Transcatheter Pacing System (TPS). METHODS: Implanted patients from the Micra TPS and the Micra Continued Access study (N = 989) were analyzed and compared to 2667 patients with transvenous pacemakers (TVP)...

Leadless pacing is now an established alternative to conventional pacing with subcutaneous pocket and transvenous lead for patients with class I or II single-chamber pacing indication. Available 12-month follow-up data shows a 48% fewer major complication rate in patients with Micra™ compared to a historical control group in a nonrandomized study [1]. There is one system with Food and Drug Administration (FDA) approval and two with the Communauté Européenne (CE) mark. The OPS code for the implantation is 8-83d...

BACKGROUND: The Nanostim leadless pacemaker (LP) met the primary endpoints in an IDE trial, and was shown to be fully retrievable percutaneously. In October 2016, St Jude Medical, issued a worldwide alert of a battery malfunction that caused lost pacing output and LP communication. OBJECTIVE: The objective here is to report the battery failure mechanism and incidence and the worldwide patient management including device retrieval experiences. METHODS: The affected LP battery is a custom Lithium-Carbon Monofluoride (Li-CFx) cell...

Leadless pacemaker (LP) technology was recently developed and introduced for clinical purpose as an alternative to traditional systems in order to reduce leads and pocket-related complications. Currently, two self-contained right ventricular pacemaker implanted by using a femoral percutaneous approach have been developed and initial results seem promising. Although the clinical use is still limited to the right ventricular pacing, the LP currently represents a valid and alternative solution in several settings, when the standard pacemaker cannot be used or its use is associated with higher risk of complications...

Aims: Leadless cardiac pacing has recently been proposed as alternative to conventional right ventricular (RV) pacing. With this approach, devices are directly screwed or fixed with tines in the RV wall, but the possible consequences on RV and tricuspid valve (TV) structure and function remain unknown. We thus conducted a study to evaluate this potential impact in chronically implanted patients. Methods and results: Repeated echocardiographic studies were performed prior to implantation, at discharge, and 2 months thereafter on all consecutive patients implanted with a leadless pacemaker at our centre between October 2014 and end-December 2015...

The number of children and adult with congenital heart disease requiring implantation of cardiac pacemaker or cardioverter defibrillator is constantly increasing. The lead between stimulation/defibrillation site and the generator constitutes the main weakpoint of those devices despite the numerous recent technological advances: use of bipolar probes, corticoid elution electrodes, insulation improvement, magnetic resonance imaging (MRI) compatibility. Risk of device failure remains high in this population. Long term adverse events with endovascular devices remain high...

Since the first transvenous pacemaker implantation, that took place 50 years ago, important progress has been achieved in pacing technology. Consequently, today, more than 700,000 pacemakers are implanted annually worldwide. However, conventional pacemakers' implantation carries a non-negligible risk of periprocedural and long-term complications associated with the transvenous leads and pacemaker pocket. Recently, Leadless Pacing Systems have emerged as a therapeutic alternative to conventional pacing systems providing therapy for patients with bradyarrhythmias, while eliminating potential transvenous leads and pacemaker pocket related complications...

BACKGROUND: First-in-man studies of leadless pacemakers have demonstrated high rates of implant success, and safety and efficacy objectives were achieved. Outside of the investigational setting, there are concerns, particularly over cardiac effusion and perforation, device dislodgement, infection, telemetry, and battery issues. OBJECTIVE: The acute performance of the Micra transcatheter pacemaker from a worldwide postapproval registry is reported. METHODS: The registry is an ongoing prospective single-arm observational study designed to assess the safety and effectiveness of Micra in the postapproval setting...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

There have been many evolutionary milestones in cardiac implantable electronic device (CIED) therapy over the past few decades. These advancements have created new  challenges. Right ventricular pacing was the original (late 1950s) breakthrough, however the risk of pacing induced dyssynchrony has become evident. Biventricular pacing provided a viable way to mitigate dyssynchrony, but only benefits certain patients (primarily left bundle branch block and QRS duration ≥150 ms with depressed left ventricular (LV) function)...

BACKGROUND: Leadless pacemaker systems have been designed to avoid the need for a pocket and transvenous lead. However, delivery of this therapy requires a new catheter-based procedure. This study evaluates the role of operator experience and different training strategies on procedural outcomes. METHODS: A total of 726 patients underwent implant attempt with the Micra transcatheter pacing system (TPS; Medtronic, Minneapolis, MN, USA) by 94 operators trained in a teaching laboratory using a simulator, cadaver, and large animal models (lab training) or locally at the hospital with simulator/demo model and proctorship (hospital training)...

A new technology, leadless pacemaker therapy, was recently introduced clinically to address lead- and pocket-related complications in conventional transvenous pacemaker therapy. These leadless devices are self-contained right ventricular single-chamber pacemakers implanted by using a femoral percutaneous approach. In this review of available clinical data on leadless pacemakers, early results with leadless devices are compared with historical results with conventional single-chamber pacing. Both presently manufactured leadless pacemakers show similar complications, which are mostly related to the implant procedure: cardiac perforation, device dislocation, and femoral vascular access site complications...
