Anticoagulation Therapy in Patients Undergoing Micra Leadless Pacemaker
Implantation
Abstract
Over the past decade, there has been significant improvement in the
treatment of diseases of the conduction system and symptomatic
bradyarrhythmias with the development of leadless pacemaker systems. The
Micra transcatheter pacemaker system has been shown to mitigate a lot of
the complications associated with traditional pacing systems, which are
notably skin pocket and lead-related complications. Numerous studies
have shown the low complication rates associated with Micra procedure;
however, there have been no specific guidelines or recommendations
surrounding periprocedural anticoagulant therapy. This is important
because a significant percentage of patients requiring pacemaker therapy
have an indication for anticoagulation therapy as well. Multiple studies
have shown the safety of uninterrupted anticoagulation during Micra
implant, however, there is insufficient high-quality data to recommend
periprocedural systemic use of anticoagulation. In this paper, we review
the available data surrounding anticoagulation therapy in patients
undergoing Micra implantation and the potential bleeding risks
associated with this procedure.
