Aveir VR, retrievable leadless pacing in the young.

Area of Science:

• Cardiology
• Pediatric Electrophysiology
• Medical Device Technology

Background:

• Successful implantation of the Aveir VR leadless pacemaker has been documented in adults.
• Limited data exists on the safety and feasibility of Aveir VR implantation in pediatric populations.

Purpose of the Study:

• To evaluate the safety and feasibility of Aveir VR leadless pacemaker implantation in patients aged 21 years or younger.
• To assess pacing parameters and outcomes in young patients following Aveir VR implantation.

Main Methods:

• A retrospective observational study was conducted on 10 pediatric patients (≦21 years) who underwent Aveir VR implantation.
• Implantation was performed via internal jugular or femoral venous approaches.
• Data collected included patient demographics, pacing thresholds, longevity, and complications at implantation and follow-up.

Main Results:

• Ten pediatric patients (median age 12.5-17 years, 80% male) received Aveir VR leadless pacemakers.
• Implantations were primarily via the internal jugular vein (90%).
• Indications included heart block (60%) and sinus pauses (40%). Pacing parameters remained adequate through a median 9-month follow-up, with a predicted longevity of 23.8 years and no reported complications.

Conclusions:

• Aveir VR leadless pacemaker implantation is a feasible and safe procedure in the pediatric population.
• Stable pacing parameters and good predicted longevity support the use of Aveir VR in young patients.
• The internal jugular and femoral venous approaches are viable for leadless pacemaker implantation in this demographic.
