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) 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...

The implantable cardioverter-defibrillator (ICD) has shown its superiority to anti-arrhythmic drugs in the prevention of sudden cardiac death. However, the conventional transvenous ICDs are still associated with substantial risks and comorbidities mainly related to the transvenous leads. The recent advent of an entirely sub-cutaneous ICD (S-ICD) represents an important progress in the defibrillation technology towards a less invasive approach. Clinical data are growing regarding the safety and efficacy of S-ICD in prevention of sudden cardiac death in selected patients without pacing indications...

Leadless pacemakers will most likely be the future of cardiac pacing. Leadless pacing employs a single-chamber system to pace only the right ventricle and is fully self-contained, which eliminates the need for leads. These systems, implanted by using a transcatheter sheath, are indicated for patients who need right ventricular pacing only. These devices enable patients to avoid lead-related complications, from lead fracture to extraction challenges, as well as pocket-related complications such as infection and disfigurement...

BACKGROUND: Early performance of the Micra transcatheter pacemaker from the global clinical trial reported a 99.2% implant success rate, low and stable pacing capture thresholds, and a low (4.0%) rate of major complications up to 6 months. OBJECTIVE: The purpose of this report was to describe the prespecified long-term safety objective of Micra at 12 months and electrical performance through 24 months. METHODS: The Micra Transcatheter Pacing Study was a prospective single-arm study designed to assess the safety and efficacy of the Micra VVIR leadless/intracardiac pacemaker...

BACKGROUND: Device repositioning during Micra leadless pacemaker implantation may be required to achieve optimal pacing thresholds. OBJECTIVE: The purpose of this study was to describe the natural history of acute elevated Micra vs traditional transvenous lead thresholds. METHODS: Micra study VVI patients with threshold data (at 0.24 ms) at implant (n = 711) were compared with Capture study patients with de novo transvenous leads at 0.4 ms (n = 538)...

INTRODUCTION AND OBJECTIVES: Currently, studies on the leadless pacemaker (Micra) have mostly been limited to clinical trials with less than 6 months' follow-up and they often fail to reflect real population outcomes. We sought to evaluate electrical parameters at implantation and chronologically during follow-up, as well as the safety of this new technique. METHODS: This prospective, observational study included 30 consecutive patients, all ≥ 65 years, with an indication for single-chamber pacemaker implantation...
