The young patient had been under observation for years due to congenital complete heart block-a rare condition impacting approximately 1 in 15,000 to 22,000 births.This condition, which can lead to sudden cardiac arrest, disrupts the natural timing of the heartbeat. Congenital complete heart block can stem from corrected congenital heart defects, genetic factors, or, in some cases, maternal antibody exposure.
The Promise of Leadless Pacemakers
Traditionally, pacemakers require leads-wires-to connect to the heart. However, these leads can cause complications over time, such as infections or malfunctions. Leadless pacemakers, a newer technology, offer a compelling choice as they are substantially smaller and are absorbed by the heart itself. FDA approval for these devices in adults came in 2023, but their application in pediatric cases presented unique challenges.
Minimally Invasive Procedure and Rapid Recovery
Dr. Cortez and his team opted for a minimally invasive approach, implanting the AVEIR dual-chamber leadless pacemaker through the patient’s right internal jugular vein. this method allows for greater mobility and a faster return to activities, including sports.The procedure took place in the UC Davis Electrophysiology Lab, and the patient experienced no complications.within three months, the patient was able to fully resume their active lifestyle.
“This breakthrough means that children can now benefit from pacemaker technology without the long-term risks associated with customary leads,” Dr. Cortez explained. “Whether a child requires pacing of the upper chambers, lower chambers, or both, they can now safely receive leadless pacing with minimal recovery time and no activity restrictions.”
A History of Firsts for Dr. Cortez
This isn’t the first time Dr. Cortez has pushed the boundaries of pediatric cardiac care. In 2023, he performed the world’s first implantation of a retrievable leadless pacemaker in a child. Five years prior, he pioneered the implantation of a Micra single-chamber leadless pacemaker via the internal jugular vein in a pediatric patient.
Key Differences: Traditional vs. Leadless Pacemakers
| Feature | Traditional Pacemaker | Leadless Pacemaker |
|---|---|---|
| Size | Larger | 10x Smaller |
| Leads | Requires Leads | No Leads |
| Invasiveness | More Invasive | Minimally Invasive |
| Complications | Potential for Lead-Related Issues | Reduced Risk of Lead-Related Issues |
Understanding Congenital Heart Block: Congenital heart block occurs when the electrical signals that coordinate the heart’s rhythm are disrupted before birth. This can lead to a dangerously slow heart rate. Early diagnosis and intervention are crucial. According to the Centers for Disease control and Prevention (CDC), the severity of congenital heart block can vary widely, requiring different levels of treatment, from observation to pacemaker implantation.
Did You Know? The advancement of leadless pacemakers represents a significant advance in cardiovascular technology, offering a more streamlined and potentially safer option for patients of all ages.
Pro Tip: If you or your child experiences symptoms like dizziness, fainting, or shortness of breath, consult a cardiologist promptly. Early detection is key to managing heart conditions.
Frequently asked Questions about Leadless Pacemakers
- What is a leadless pacemaker? A leadless pacemaker is a small device implanted directly into the heart without the need for wires or leads.
- Are leadless pacemakers safe for children? Yes, recent advancements have made leadless pacemakers a safe and effective option for children with certain heart conditions.
- What are the benefits of a leadless pacemaker? They are smaller, less invasive, and reduce the risk of lead-related complications.
- How long does it take to recover from a leadless pacemaker implantation? Recovery is typically faster than with traditional pacemakers, often allowing patients to resume normal activities within weeks.
- What is congenital complete heart block? It is a rare heart condition present at birth where there’s a complete disruption of the electrical signals that control the heartbeat.

What are the primary advantages of dual-chamber leadless pacemakers over single-chamber systems in pediatric patients?

Understanding Leadless Pacemakers & Pediatric Cardiology
The field of pediatric cardiology has witnessed a groundbreaking advancement: the first successful implantation of dual-chamber leadless pacemakers in pediatric patients. Traditionally, pacemakers in children required leads – thin, insulated wires – threaded through veins to reach the heart. These leads can pose complications like infection, dislodgement, and the need for future revisions as the child grows.Leadless pacemakers, a relatively new technology, offer a compelling alternative, and the recent achievement of dual-chamber functionality expands their applicability significantly. This represents a major step forward in pediatric pacemaker therapy.
What are Dual-Chamber Leadless Pacemakers?
Unlike single-chamber leadless pacemakers that pace only one chamber of the heart (typically the right ventricle), dual-chamber systems pace both the atrium and the ventricle. This coordinated pacing more closely mimics the natural rhythm of the heart, offering several physiological benefits.
Here’s a breakdown:
Atrial Pacing: Helps maintain proper timing between atrial and ventricular contractions, improving cardiac output.
Ventricular Pacing: Provides support when the ventricle beats too slowly or irregularly.
Sensing Capabilities: Dual-chamber devices can sense the heart’s natural electrical activity in both chambers, adjusting pacing as needed. This is crucial for optimizing heart function and minimizing needless pacing.
Leadless Design: the entire pacemaker is self-contained, typically about the size of a large vitamin capsule, and implanted directly into the heart chamber via a catheter – no leads required.
The Significance for Pediatric Patients
Traditional pacemakers, while life-saving, present unique challenges in children. Growth necessitates led replacements or revisions, increasing the risk of complications. Leadless pacemakers address these concerns:
Reduced Revision Rate: Eliminating leads significantly reduces the need for future surgeries as the child grows.
lower Infection Risk: Fewer components mean a decreased risk of infection, a serious concern with implanted devices.
Improved Quality of Life: Children can participate in more activities with less worry about device-related issues.
Long-Term Durability: Ongoing research focuses on the long-term durability of these devices in a growing pediatric population. Pediatric heart failure management benefits greatly from these advancements.
The Implantation Procedure: A Step-by-Step Overview
The implantation of a dual-chamber leadless pacemaker is a minimally invasive procedure. here’s a general outline:
- Preparation: The patient undergoes pre-operative evaluation, including ECG, echocardiogram, and potentially cardiac MRI.
- Access: A small incision is made, typically in the groin, to access a vein.
- Catheter insertion: A specialized catheter is guided through the vein and into the heart.
- Pacemaker Deployment: The leadless pacemaker is deployed into the desired chamber (right atrium and right ventricle). Precise positioning is crucial.
- Testing & programming: The pacemaker’s function is thoroughly tested and programmed to meet the patient’s specific needs. Pacemaker programming is a critical step.
- Closure: The access site is closed, and the patient is monitored closely.
patient Selection Criteria
Not all pediatric patients are candidates for dual-chamber leadless pacemakers. Careful patient selection is paramount.Key considerations include:
Underlying Heart Condition: Conditions like complete heart block, sick sinus syndrome, and certain congenital heart defects may warrant a pacemaker.
Age & Size: The size of the pacemaker and the patient’s anatomy must be compatible.
Chamber Anatomy: Adequate chamber size and appropriate anatomy are necessary for successful implantation and fixation.
Overall Health: The patient’s overall health status is assessed to ensure they can tolerate the procedure.Congenital heart disease often necessitates pacemaker intervention.
Benefits of Dual-Chamber Pacing in Children
The advantages of dual-chamber pacing over single-chamber pacing are particularly relevant for growing children:
Physiological Pacing: Mimics the natural heart rhythm, optimizing cardiac output and minimizing energy expenditure.
Improved Atrial Function: Maintaining atrial contribution to ventricular filling enhances overall heart performance.
Reduced Risk of Atrial Fibrillation: Appropriate atrial pacing can potentially reduce the risk of developing atrial fibrillation, a common arrhythmia.
Enhanced Exercise Tolerance: Coordinated pacing allows for better heart rate responsiveness during physical activity.
