Advancements in Leadless Pacemakers: What the Second-generation Micra AV2 Brings to Cardiac Care.

Abstract

Leadless pacemakers are considered one of the major technological advancements in cardiology in recent years. Many efforts are made to provide physiological atrio-ventricular (AV) pacing. With the first-generation leadless ventricular, dual, dual (VDD) pacemaker, Micra AV (Medtronic, Inc., Minneapolis, MN, USA), a high variability in AV synchrony was reported. A second generation, Micra AV2, is now available for clinical use, promising smarter and higher automatic AV synchrony. This article reviews the different improvements proposed for this new device.
