Key result
Implantation of an Aveir dual-chamber leadless pacemaker via the right internal jugular vein was successful in a 65-year-old woman, yielding stable thresholds and sensing at 8-day follow-up.
Why the study?
Permanent pacemaker implantation is preferred for symptomatic sinus node dysfunction, but alternative access is needed when femoral veins are inaccessible.
Does implantation of a dual-chamber leadless pacemaker via the right internal jugular vein provide safe and effective pacing in a patient with inaccessible femoral veins?

Does implantation of a dual-chamber leadless pacemaker via the right internal jugular vein provide safe and effective pacing in a patient with inaccessible femoral veins?
Implantation of a dual-chamber leadless pacemaker via the right internal jugular vein is feasible and safe in patients with inaccessible femoral veins.
Should not yet change practice; hypothesis-generating for jugular access in femoral-inaccessible cases and requires larger prospective studies.
INTRODUCTION: Sinus node dysfunction (SND) is a disorder defined by abnormal initiation and conduction of electrical signals from the sinoatrial node. The preferred first-line treatment for a patient with symptomatic SND is a permanent pacemaker implant. We describe the implantation of an Aveir dual-chamber leadless pacemaker through the right internal jugular vein in a 65-year-old female patient with inaccessible femoral veins and a chemotherapy port in the left internal jugular vein. METHODS: A retrospective review was performed at the University of California at Davis of the dual-chamber leadless pacemaker (Aveir DR) procedure. RESULTS: A 65-year-old female with a history of chronic dialysis use and chemotherapy, with persistence of left internal jugular vein port, presented with symptomatic bradycardia. After a failed attempt at an outside institution, she presented for a dual-chamber leadless pacemaker implant at our institution. Via the right internal jugular vein, the Aveir VR was deployed with stable thresholds, impedance, and sensing into the ventricular septum, with a subsequent atrial device being deployed with stable thresholds, impedance, and sensing into the right atrial appendage. Follow-up at 8 days demonstrated a ventricular threshold of 0.75V at 0.2 ms, impedance of 440 Ohms, and sensing of 9.9 mV. Follow-up atrial threshold of 0.75V at 0.2 ms, impedance of 400 Ohms, and P wave sensing of 0.8 mV. CONCLUSION: Placement of the Aveir dual chamber leadless pacemaker is safe in an adult patient without any complications.
