Leadless pacemaker indications

The primary advantage of a leadless pacemaker is the elimination of several complications associated with transvenous pacemakers and leads: pocket infections, hematoma, lead dislodgment, and lead fracture. The leadless pacemaker also has cosmetic appeal because there is no chest incision or visible pacemaker pocket Leadless pacemaker - state of art and incoming developments to broaden indications. Pacing Clin Electrophysiol. 2020 Oct 22. doi: 10.1111/pace.14097. Online ahead of print Leadless Pacemakers Traditional pacemakers have been the standard treatment option for patients with severe/symptomatic bradycardia, an arrhythmia indicating an unusually slow heart rate Aetna considers leadless cardiac pacemakers experimental and investigational for arrhythmias and all other indications because of insufficient evidence of its safety and effectiveness The leadless pacemaker eliminates the need for a device pocket and insertion of a pacing lead which are integral elements of traditional pacing systems. The removal of these elements eliminate an important source of complications associated with traditional pacing systems while providing similar benefits. Leadless pacemakers are delivered via catheter to the heart, and function similarly to other transvenous single-chamber ventricular pacemakers

• Leadless pacemakers represent new leap forward in technology • May address the Achilles' heel of traditional pacemaker device • Appropriate patients include those currently indication for single-chamber device • May see creep in single chamber implants for other indications until technology catches u Pacemakers are used to treat patients with brady-arrythmias, slow heart rhythms that may occur as a result of disease in the heart's conduction system (such as the SA node, AV node or His-Purkinje network). A leadless pacemaker is small self-contained device that is inserted in the right ventricle of the heart

In the LEADLESS trial, 33 patients had a single-chamber leadless cardiac pacer attempted; 97% had a successful implant. One patient developed RV perforation and another cardiac tamponade during the implant. The overall complication free rate was 94%. 6 Pacing performance was stable in all implanted patients at three months and one year (figure 3) Leadless pacemakers are self-contained. Doctors implant them into the heart's right ventricle via a catheter threaded through the leg, which is then removed once the device is deployed internally. They require no wires and no surgical pocket in the heart. They help keep a patient's heart from beating too slowly, a condition called bradycardia The Micra leadless pacemaker includes time-tested, valuable features, including: Permitting you to safely undergo magnetic resonance imaging (MRI), a diagnostic tool doctors use to see inside the body. Adjusting your heart rate automatically by sensing changes in your body related to your activity level and adjusting your heart rate accordingly

In patients with a left ventricular ejection fraction between 36% to 50% and AV block, who have an indication for permanent pacing and are expected to require ventricular pacing >40% of the time, techniques which provide more physiologic ventricular activation (cardiac resynchronization therapy or His bundle pacing) are reasonable in preference.

Herein, we report a multicenter experience on the feasibility and safety of acute retrieval (<6 weeks) and chronic retrieval (>6 weeks) of the leadless cardiac pacemaker in humans

Leadless pacing systems are a viable alternative when extraction of an infected conventional pacing system is required. Leadless pacemakers have also shown resistance to infection even when inserted at the time of or shortly after conventional system extraction.1,2 Our case documents the rare occurrence of Micra Transcatheter Pacemaker System (Medtronic, Minneapolis, MN) infection in a patient. Leadless pacing systems can be implanted successfully with a low complication rate, if suggestions for indications and technical requirements are followed. An overview of the two utilized leadless cardiac pacing systems is given, specifically highlighting clinical advantages as well as current knowledge of performance and complication rates The Micra™ leadless pacemaker is a safe and efficient pacing option in patients after valve intervention. The absence of pacing lead through the tricuspid valve as well as a reduction in device infections during follow-up are significant advantages for this population ABSTRACT. Leadless pacemakers are evolving as a new technologic alternative to conventional transvenous pacemakers, though potential short-term and long-term complications have been recognized.The two currently available right ventricular leadless pacing systems are the Nanostim™ Leadless Cardiac Pacemaker (Abbott Laboratories, Chicago, IL, USA) and the Micra™ Transcatheter Pacing System. Pacemakers are electric activity generating devices used to treat patients with slow heart rate or symptomatic heart blocks and in patients with heart failure.[1] All cardiac pacemakers are generally composed of a pulse generator that generates the electrical current required for stimulation of heart musculature and one or two electrodes (also referred to as leads), which are responsible for.

Conduction abnormalities frequently occur following TAVR, requiring implantation of a permanent pacemaker, ideally with preservation of atrioventricular (AV) synchrony. There is no consensus on the placement of permanent pacemakers and no current guidelines exist for the use of leadless pacemakers in this setting The device description/function or indication may have changed. Be sure to look at the supplements to get an up-to-date information on device changes. The labeling included below is the version at time of approval of the original PMA or panel track supplement and may not represent the most recent labeling In February 2016, the Micra Transcatheter Pacing Study Group demonstrated the safety and efficacy of implantation with the Micra leadless cardiac pacemaker (Medtronic, Dublin, Ireland) (Figure 3) in 725 patients with an indication for a VVI pacemaker Introduction. Leadless pacemaker has been demonstrated to be as effective and safer as compared to a traditional transvenous pacemaker. Moreover, this type of device can reduce or even eliminate infective complications related to the endocardial lead and subcutaneous pocket in traditional pacemaker [].This latter aspect should be of particular interest in patients after heart transplantation. The Micra leadless pacemaker is a reasonable pacing option in patients with ESRD on hemodialysis and it appears to have an acceptable safety profile through mid-term follow-up. The absence of device infection during a mean follow-up of 6.2 months and the sparing of upper venous circulation are significant advantages of leadless pacing in this.
