Sofian Johar, Nazar Luqman
A left atrial appendage occluder device (Watchman) and leadless pacemaker (Micra) was implanted from a single right femoral vein access in a 73-year-old female patient with persistent atrial fibrillation and symptomatic tachy-brady syndrome and unable to take oral anticoagulants. Standard methods of implantation were followed for both procedures. The Watchman device was implanted first followed by dilatation of the same venous access site in order to implant Micra transcatheter pacing system. The patient tolerated the procedures well and there were no complications...

Leadless pacemaker therapy is a new technology that aims at avoiding lead- and pocket-related complications of conventional transvenous and epicardial pacing. To date, 2 self-contained leadless pacemakers for right ventricular pacing have been clinically available: the Nanostim Leadless Pacemaker System and the Micra Transcatheter Pacing System. Additionally, a new multicomponent leadless pacemaker for endocardial left ventricular pacing has been proposed as an alternative choice for cardiac resynchronization therapy...

BACKGROUND: Due to relatively newer technology, experience with retrieval of Micra transcatheter pacing system (TPS) is limited. Although, it is recommended to abandon the TPS at end of life, certain situations such as endovascular infections or device embolization warrant retrieval. OBJECTIVES: To report worldwide experience of successful retrieval for Micra TPS. METHODS: The list of all successful retrievals for the currently available leadless pacemakers (LPs) was obtained from the manufacturer of Micra TPS...

Aims: A prospective, single-arm, multicentre, post-market study was conducted to confirm the short-term safety of the Nanostim™ leadless pacemaker (LP). In this study, we report the primary results of the LEADLESS Observational Study. Methods and results: Subjects meeting VVIR pacemaker indications were enrolled and followed up after successful LP implantation, prior to discharge and post-implantation at 90 days, 180 days, and every 6 months thereafter for the assessment of adverse events...

The purpose of this European Heart Rhythm Association (EHRA) survey is to provide an overview of the current use of leadless pacemakers (LLPM) across a broad range of European centres. An online questionnaire was sent to centres participating in the EHRA Electrophysiology Research Network. Questions dealt with standards of care and policies used for patient management, indications, and techniques of implantation of LLPM. In total, 52 centres participated in the survey. Most (86%) reported using LLPM, although 82% of these centres implanted <30 LLPM devices during the last 12 months...

OBJECTIVE: cardiac pacemakers require regular medical follow-ups to ensure proper functioning. However, device replacements due to battery depletion are common and account for ∼25% of all implantation procedures. Furthermore, conventional pacemakers require pacemaker leads which are prone to fractures, dislocations or isolation defects. The ensuing surgical interventions increase risks for the patients and costs that need to be avoided. METHODS: in this study, we present a method to harvest energy from endocardial heart motions...

Vasovagal syncope is characterized by vasodilatation and/or bradycardia and thereby a fall in arterial BP and global cerebral perfusion in response to a trigger. Although it is a benign condition, patients with frequent and traumatic episodes need treatment in order to improve quality of life. We describe the case of a 17-years-old boy suffering from cardioinhibitory syncope. At the end of a complete negative cardiac and neurological examination, a loop recorder was implanted. During the subsequent follow-up the ILR documented a 9-s pause...

Congenital heart disease patients are considered a unique group of patients regarding their high risk of conduction abnormalities , whether de novo or surgically induced , and the challenges in both implantation and management of device related complications. We present a case of a pacemaker-dependent patient with congenital heart disease who experienced complications of both previous epicardial and transvenous pacing which rendered her a non-suitable candidate of both routes.

Implantable cardiac pacemakers have seen remarkable progress in the last sixty years and remained as cornerstone therapy for symptomatic bradycardia. Despite this progress the current day traditional transvenous implanted pacemaker systems are limited by the need for a surgically created pocket for the generator, indwelling leads in the vascular system and lastly passage through the tricuspid valve. A majority of the implant and explant related complications are due to the surgical pocket and indwelling leads...

With the advent of "wireless" endocardial pacing, the subcutaneous implantable cardioverter defibrillator, and leadless pacemakers comes an added layer of complexity to the perioperative management of cardiovascular implantable electronic devices (CIED). Since no formal recommendations currently exist for these new CIED technologies, preoperative identification of these devices, understanding their functionality, and developing an individualized perioperative management plan are imperative for the anesthesiologist...

BACKGROUND: Leadless pacemaker can be considered as a technical revolution in cardiac pacing devices, with clear advantages over conventional pacemakers in overcoming all lead related complications. However, the management of these devices once they reach the end of life of the battery is still controversial. In the next years there will be an increase in the need to define a clear strategy in the management of leadless PM once they reach their EOL. Safe extraction of these devices will define in a great manner this strategy METHODS: We performed the extraction of three functioning Nanostim leadless pacemaker prophylactically in two females and one male patients part of the Nanostim battery depletion field action recommendation...

AIM: Leadless cardiac pacemaker has been developed to reduce complications related to cardiac pacing and is considered as an alternative to conventional pacemaker although safety and efficacy data in clinical practice are limited. The purpose of this study was to investigate the safety and efficacy profile of Micra Transcatheter Pacing System (TPS) used in daily clinical activity with a focus on challenging cases for conventional pacing. METHODS: A total of 66 patients (46 men, 79...

Electrogenesis in the heart begins in the sinoatrial node and proceeds down the conduction system to originate the heartbeat. Conduction system disorders lead to slow heart rates that are insufficient to support the circulation, necessitating implantation of electronic pacemakers. The typical electronic pacemaker consists of a subcutaneous generator and battery module attached to one or more endocardial leads. New leadless pacemakers can be implanted directly into the right ventricular apex, providing single-chamber pacing without a subcutaneous generator...

Leadless cardiac pacemakers (LCP) have become available recently. Both its acute and long-term performance in a large population of patients remain to be tested. Subacute rise in pacing threshold has been reported as an uncommon complication. On the other hand, the retrieval technique for LCP with passive fixation mechanism has not been previously described in details. Herein we report a newly recognized complication of an acute rise in pacing threshold very soon after implantation of an LCP without radiographic dislodgement...

PURPOSE OF REVIEW: Pacing technology for many decades has been composed of a generator attached to leads that are usually transvenous. Recently, leadless pacemakers have been studied in clinical settings and now available for use in many countries. This includes the single-component Nanostim Leadless Cardiac Pacemaker and Micra Transcatheter Pacing System, as well as the multicomponent Wireless Stimulation Endocardial system. RECENT FINDINGS: Clinical studies in single-component leadless pacing technology has shown that they can be successfully implanted with minimal complications...
