Pediatric cardiologists at UC Davis have reached a remarkable milestone by becoming the first in the world to implant a dual chamber leadless pacemaker in a pediatric patient.
This unprecedented achievement was led by Dan Cortez, the Director of Pediatric Electrophysiology, and has been detailed in the journal PACE: Pacing and Clinical Electrophysiology.
Patient Background
The groundbreaking procedure was performed on a 13-year-old boy suffering from congenital complete heart block, a rare condition occurring in about 1 in every 15,000 to 22,000 children.
The child was referred to the electrophysiology clinic after experiencing episodes of presyncope, which caused dizziness and near-fainting.
Congenital complete heart block often requires the implantation of a pacemaker to mitigate severe complications, including the risk of sudden cardiac arrest.
This rare condition may be the result of repaired congenital heart defects, genetic factors, or even maternal antibodies during pregnancy.
Innovative Procedure
Before moving forward, Cortez reviewed a battery of electrocardiograms and Holter monitor results that revealed a worrying decline in the patient’s average heart rates.
After thoroughly discussing available pacemaker options with both the patient and his family, the dual chamber leadless pacemaker emerged as the clear choice.
This innovative device is able to stimulate both the atrial and ventricular chambers of the heart effectively, resonating with the patient’s desire to remain active in sports without restrictions.
The procedure took place via the boy’s right internal jugular vein, a strategic choice that facilitated quicker mobility and a smoother return to his athletic pursuits.
Conducted in the UC Davis Electrophysiology Lab, the process was minimally invasive and went off without any complications.
Just three months post-implantation, the young patient returned to his routine exercise and sporting activities, signifying a successful outcome.
Advancements in Pacemaker Technology
One of the standout features of the AVEIR dual chamber leadless pacemaker is its design.
Unlike traditional devices, it lacks leads and wires, measuring around ten times smaller than conventional pacemakers.
Additionally, this pacemaker is designed to be absorbed by the heart itself, reducing the long-term complications often associated with traditional pacing systems.
Approved for adult use by the FDA in 2023, this device is anticipated to offer significant benefits for pediatric patients as well.
Dr. Cortez has made significant strides in pediatric electrophysiology, being the first in the world to successfully implant a retrievable leadless pacemaker into a child earlier this year.
His prior achievements include the groundbreaking installation of a Micra single-chamber leadless pacemaker via the internal jugular vein in a pediatric patient five years ago.
These advancements highlight a commitment to improving care and outcomes for young patients with complex heart conditions.
