“…Although most of these patients progressed to complete recovery from infection, it is not clear how many among them had distal lead endocarditis. 7 Bacteremia caused by MRSA, the predominant organisms in cardiac implantable electronic device infection, is associated with high mortality. These organisms form a protective biofilm on the surface of the Micra device, thus rendering them antibiotic-resistant.…”

“…Some studies on sheep have demonstrated the possibility of safely extracting the TPS percutaneously 7, 8. The first-in-human extraction of a Micra TPS 3 weeks after implantation owing to elevated capture threshold was recently reported by Karim et al 9 In this report, we describe the world’s first infected Micra TPS, which eventually led to its extraction percutaneously 1 month after implantation.…”

We report the first-in-human retrieval of a chronically implanted Micra transcatheter pacing system (TPS; Medtronic, Minneapolis, MN, USA). A 41-year-old woman suffering from third-degree atrioventricular block was successfully implanted with a TPS in the low septum of the right ventricle. After 29 months, due to an increased electrical threshold and 100% pacing percentage, the device showed low battery voltage. Despite the long implant duration, the attempt of device retrieval using a snare loop inserted in the delivery system of a TPS was successful. In the same procedure, a new leadless pacemaker was implanted in the high right ventricular septum with optimal pacing threshold.

“…However, data of extraction of chronically implanted devices are limited, and there is no experience with extraction of systems implanted for longer than 3 years in humans. Reddy et al report successful extraction of 10/11 devices implanted >6 weeks (range 88–1188 days) [ 11 ] and Bongiorni et al and Bonner et al after 28 months in sheep [ 12 , 13 ]. Of note, the devices seem to have the potential to become completely encapsulated into the heart over time.…”

Leadless Pacing: Current State and Future Direction

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.3 and the procedure has recently been rated as a “new Examination and Treatment Method (NUB)” in the German DRG system, meaning adequate reimbursement is negotiable with health insurance providers. The systems offer similar generator longevity and programming possibilities as conventional pacemaker systems, including rate response, remote monitoring, and MRI safety. The biggest downsides to date are limitations to single-chamber stimulation, lack of long-time data, and concerns of handling of the system at the end of its life span. However, implant procedure complication rates and procedure times do not exceed conventional pacemaker operations, and proper training and patient selection is provided.
