The AVEIR twin chamber leadless pacemaker. Credit score: UC Davis
UC Davis Director of Pediatric Electrophysiology Dan Cortez has set one other world report: He’s the primary to implant a twin chamber leadless pacemaker in a toddler. His case report was revealed this week within the journal Pacing and Scientific Electrophysiology.
A 13-year-old affected person was referred to the UC Davis pediatric electrophysiology clinic for presyncope, a sense of lightheadedness or dizziness with out really fainting, after being monitored for years for congenital full coronary heart block.
Pacemakers are usually positioned in youngsters with congenital full coronary heart block, a uncommon situation that may result in sudden loss of life and impacts 1 in about 15,000 to 22,000 youngsters. Congenital full coronary heart block could happen as a consequence of repaired congenital coronary heart illness or genetic predisposition. It may also be acquired from publicity to sure maternal antibodies.
After serial electrocardiograms and Holter screens confirmed progressively decrease common coronary heart charges, Cortez talked with the affected person and their household about pacemaker choices.
Twin chamber leadless pacemakers assist regulate the guts’s rhythm by stimulating the guts’s higher (atrial) and decrease (ventricular) chambers. As a result of the affected person needed to stay energetic in sports activities with out restrictions, leadless pacing was offered as an possibility, and the household agreed.
The AVEIR twin chamber leadless pacemaker was implanted by way of the affected person’s proper inner jugular vein (as a substitute of the femoral vein) so the affected person might transfer simply and return to sports activities sooner. The minimally invasive process befell within the UC Davis Electrophysiology Lab.
The affected person had no problems throughout or after the process. Three months later, the affected person was in a position to resume train and play sports activities.
The AVEIR machine is completely different from conventional pacemakers partially as a result of it has no leads or cords and is absorbed by the guts. It’s also 10 occasions smaller than a standard pacemaker. This pacemaker has been implanted in adults throughout the nation because it acquired FDA 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 mentioned. “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 primary doctor on the planet to implant a retrievable leadless pacemaker in a toddler. 5 years previous to that, Cortez was the primary doctor on the planet to implant a Micra single-chamber leadless pacemaker by the interior jugular vein in a toddler.
