The pacemaker had previously been implanted in adults across the country since it received US Food and Drug Administration approval in 2023.
Summary: Dan Cortez, MD, director of pediatric electrophysiology at UC Davis, has implanted the first dual chamber leadless pacemaker in a child. The 13-year-old patient, who had a congenital complete heart block, was referred to the clinic after experiencing presyncope. The dual chamber leadless pacemaker, which helps regulate the heart’s rhythm, was chosen as a solution to allow the patient to remain active in sports. The minimally invasive procedure was performed via the internal jugular vein, and the patient resumed sports three months later. This pacemaker, approved by the FDA in 2023, is smaller and lacks leads compared to traditional pacemakers.
Key Takeaways:
- First Dual Chamber Leadless Pacemaker Implanted in a Child: A 13-year-old patient became the first to receive a dual chamber leadless pacemaker, a treatment option for congenital heart block.
- Minimally Invasive Procedure: The pacemaker was implanted via the internal jugular vein, which facilitated a quicker recovery and allowed the patient to return to sports within three months.
- New Pacemaker Design: The dual chamber leadless pacemaker, approved by the FDA in 2023, is smaller and does not require leads, potentially reducing complications seen with traditional pacemaker designs.
UC Davis director of pediatric electrophysiology Dan Cortez, MD, has implanted the first dual chamber leadless pacemaker in a child, according to his case report published in PACE: Pacing and Clinical Electrophysiology.
A 13-year-old patient was referred to the UC Davis pediatric electrophysiology clinic for presyncope, a feeling of lightheadedness or dizziness without actually fainting, after being monitored for years for congenital complete heart block.
Pacemakers are typically placed in children with congenital complete heart block, a rare condition that can lead to sudden death and affects 1 in about 15,000 to 22,000 children. Congenital complete heart block may occur due to repaired congenital heart disease or genetic predisposition. It can also be acquired from exposure to certain maternal antibodies.
Case Study
After serial electrocardiograms and Holter monitors showed progressively lower average heart rates, Cortez talked with the patient and their family about pacemaker options.
Dual chamber leadless pacemakers help regulate the heart’s rhythm by stimulating the heart’s upper (atrial) and lower (ventricular) chambers. Because the patient wanted to remain active in sports without restrictions, leadless pacing was presented as an option, and the family agreed.
The AVEIR dual chamber leadless pacemaker was implanted via the patient’s right internal jugular vein (instead of the femoral vein) so the patient could move easily and return to sports sooner. The minimally invasive procedure took place in the UC Davis Electrophysiology Lab.
The patient had no complications during or after the procedure. Three months later, the patient was able to resume exercise and play sports.
AVEIR Pacemaker Offers Smaller, Leadless Design
The AVEIR device is different from traditional pacemakers in part because it has no leads or cords and is absorbed by the heart. It is also 10 times smaller than a traditional pacemaker. This pacemaker has been implanted in adults across the country since it received US Food and Drug Administration approval in 2023.
“Everyone, kids included, can now have the benefits of pacemakers without leads and without the complications that come with leads long term,” Cortez says in a release. “No matter what kind of pacing a kid needs—atrial or ventricular, or both—they can now safely receive leadless pacing and, after the short recovery period, have no restrictions to their activity level.”
In 2023, Cortez was the first physician in the world to implant a retrievable leadless pacemaker in a child. Five years prior to that, Cortez was the first physician in the world to implant a Micra single-chamber leadless pacemaker through the internal jugular vein in a child, according to a release from CD Davis Health.
