Development of Pericarditis Following Implantation of Micra Leadless Pacemaker

Pacemakers are frequently essential in managing conduction disorders. Recently, the advancement of leadless pacemakers (LPs) has emerged, offering an alternative without the need for an upper shoulder incision or pacing leads. Despite the advantages, including reduced infection risk and improved durability, the novel nature of LPs means that some complications are still being identified. This report presents a unique case of pericarditis occurring after the implantation of a Micra leadless pacemaker (MLP) (Medtronic, Minneapolis, MN). It demonstrates the critical need for careful post-procedural monitoring to promptly detect and address potential complications associated with this emerging technology.
