The first prospective multicenter study concluded that Micra™ AV is an effective therapy for patients with AV block who would otherwise require a dual-chamber transvenous pacemaker.
View clinical dataReal-world experience reinforces safety and long-term performance of Micra VR.
The Micra Coverage with Evidence Development (CED) Study compares Micra leadless-VVI pacemakers to transvenous-VVI pacemakers and provides insights into real-world comparative effectiveness of leadless pacemakers.

Visit Medtronic AcademyThe single chamber Micra™ Transcatheter Pacing System is being described herein as Micra™ VR in order to distinguish it from the dual chamber (VDD) Micra™ AV product. When information in this document relates to both Micra AV and VR, “Micra™ Transcatheter Pacing Systems” is used to represent the portfolio of devices.
Use conditions include:
8 years = 100% VDD pacing, 60 bpm, pacing threshold 1.5 V, impedance 500 Ω, pulse width 0.24 ms.
13 years = 15% VDD pacing, 70 bpm, pacing threshold 1.5 V, impedance 600 Ω, pulse width 0.24 ms.
Use conditions included: median pacing 53.5%, median pacing threshold 0.50 V, median impedance 543 Ω; 89% of patients with > 10-year projected longevity; 99% of patients with > 5-year longevity.13
