Delivery of a Leadless Transcatheter Pacing System as First-line Therapy in a 28-kg Pediatric Patient Through Proximal Right Internal Jugular Surgical Cutdown.

The Micra™ transcatheter pacing system (TPS) (Medtronic, Minneapolis, MN, USA) is the only leadless pacemaker currently approved by the United States Food and Drug Administration. A limitation to the use of this device in the pediatric population is the large size of the delivery sheath. We present a 28-kg, nine-year-old male with symptomatic asystolic pauses who underwent successful placement of a Micra™ TPS via right internal jugular vein surgical cutdown as a first-line option. Current reports in the literature using the right internal jugular vein due to small patient size are limited to those involving patients with concurrent medical conditions that render the use of traditional systems unfavorable or contraindicated. Given the potential benefits of a leadless pacemaker system, its use in the pediatric population will likely continue to increase with time. This case describes technical strategies and procedural caveats that could aid in continued successful implantations of the Micra™ TPS in smaller patients as first-line therapy. In this report, room setup, the use of preprocedure vascular duplex studies, sheath manipulation, and a multidisciplinary approach are reviewed.
