Last week, doctors at Amsterdam University Medical Center (AUMC) successfully completed the implantation of the first dual wireless pacemaker in Europe. Cardiologists introduced a revolutionary two-part system designed to eliminate the complications associated with traditional pacemakers. Wireless pacemakers are a relatively new technology and are set to overcome many of the limitations of conventional pacemakers.
Why this is important:
The invention of pacemakers has changed the lives of many, allowing recipients to continue living normal lives. Every year, 600,000 pacemakers are implanted worldwide, but as the population ages, an increasing number of individuals will require them. Wireless pacemakers promise to advance this technology and overcome some of the limitations of traditional pacemakers.
Leadless pacemakers, a significant leap forward in cardiac care, are miniaturized devices that operate without leads – the wires traditionally used to connect the pacemaker to the heart. These devices integrate the pulse generator and electrodes into a single intracardiac unit. Since no wires are needed, the risk of complications such as infections or dislodgment is significantly reduced. The pacemaker is implanted via a minimally invasive procedure, typically creating a small incision in the groin to access a vein, allowing the device to be placed directly into the heart.
The surgery at Amsterdam UMC marked a milestone in the evolution of this technology with the implantation of a dual wireless pacemaker system. This system, consisting of two mini pacemakers placed in the atrium and ventricle, coordinates electrical impulses between them, ensuring optimal heart function. The successful procedure represents a significant advancement in patient care and may potentially reduce the complication rate of 1 in 10 seen with traditional pacemaker leads.
Advantages over traditional pacemakers
Traditional pacemakers have saved countless lives but also have disadvantages. They require a device to be implanted under the skin of the chest and leads that go to the heart, which can cause complications such as infections or fractures. The wireless pacemaker, comparable in size to a vitamin pill, offers a less invasive and more durable solution. It can be implanted using a minimally invasive procedure, leaving no scar on the chest and reducing the risk of infections. Additionally, the small size and weight minimize the psychological impact associated with visible scars and bulky devices.
The dual wireless pacemaker, as installed at the AUMC, is customizable; initially, only one device can be implanted, with the option to add a second device in the future if necessary. This flexibility caters to the changing needs of patients and exemplifies the patient-centered approach of modern medicine.

Performance and safety
A recent study published in the New England Journal of Medicine reinforces the promise of wireless pacemakers. The study evaluated a dual-chamber leadless pacemaker system and reported high safety rates and effective performance. The system achieved over 90% of the primary safety and performance endpoints, with atrioventricular synchrony – the coordination between the atria and ventricles – observed in 97.3% of patients.
The dual-chamber system, a programmable modular design, enables two-way wireless communication, maintaining the heart’s natural rhythm. This advancement addresses a limitation of earlier single-chamber leadless pacemakers, which were suitable for fewer patients because they could not support atrial pacing or consistent atrioventricular synchrony.
Real-world implications
The story of Barry Lawrence, one of the first Americans to receive a wireless pacemaker, is a testament to the real-world impact of these devices. Lawrence, a fast sports enthusiast, found that his activities were limited by a slow heartbeat, leading to fainting spells. His implantation of the Abbott Aveir Leadless Dual Chamber Pacemaker – the first on the West Coast – not only stabilized his condition but also allowed for a quick recovery without physical limitations. This case illustrates the device’s potential to enhance quality of life.
Dr. Brian Kim of Providence St. Joseph Hospital performed the procedure on Lawrence and described the device as a “game changer.” With its dual-chamber functionality and absence of leads, the pacemaker is expected to set new standards in the field of cardiac pacing. The ease of implantation and the longevity of the devices, which last 10 to 15 years before requiring simple replacement, make it even more appealing.
Cardiologist Hareld Kemps: ‘Heart failure is a growing problem in the Netherlands, technology is essential to the solution’
People with heart failure have low energy levels. As a result, everyday activities are often a major challenge, leading to social isolation. In the Netherlands, more than 250,000 people suffer from heart failure. This chronic condition means that the heart cannot pump blood effectively through the body.
Considerations and future perspectives
Despite the advantages, wireless pacemakers are not without considerations. According to the Cleveland Clinic, while such pacemakers eliminate the need for a surgical pocket and the connection of leads – common causes of complications in traditional pacemakers – they are currently limited to pacing only one ventricle and cannot defibrillate. Additionally, the initial costs are higher and there is a risk of cardiac perforation. However, the success rates of implants between 95% and 99% and the low complication rates underscore the potential of this technology.
As medical technology advances, the use of wireless pacemakers is expected to increase. The success of the dual wireless pacemaker system at AUMC, combined with ongoing research and practical experiences, suggests a shift towards less invasive, patient-friendly cardiac pacing solutions. With further development and greater accessibility, wireless pacemakers may indeed become the standard for patients needing pacing therapy.
Future Trends in Cardiac Technology: The Rise of Wireless Pacemakers
The successful implantation of Europe’s first double wireless pacemaker at the Amsterdam University Medical Center marks a revolutionary step in cardiac care. With over 600,000 traditional pacemakers implanted annually worldwide, the growth of the aging population underscores the increasing demand for these devices. Wireless pacemakers aim to address the complications associated with conventional technologies, positioning themselves as the future of cardiac pacing.
Enhanced Safety and Reduced Complications
The innovative design of leadless pacemakers eliminates the risk of infections and dislodgements commonly seen with traditional systems. By integrating the pulse generator and electrodes into a single device implanted through minimally invasive procedures, these systems reduce the likelihood of complications significantly. The minimally invasive nature not only improves safety but also enhances recovery experiences for patients, setting a new standard in patient care.
Customizable Solutions for Patients
The dual wireless pacemaker system developed at AUMC allows for initial implantation of one device with the possibility of adding a second if required. This adaptability caters to the evolving needs of patients, reflecting a more patient-centered approach in modern medicine. As technology advances, customization will likely become increasingly crucial in managing individual patient cases.
Increased Efficiency and Quality of Life
Recent studies highlight the impressive efficacy rates of this new technology, achieving high performance in patient outcomes. An example is the case of Barry Lawrence, whose implant of a dual chamber wireless pacemaker not only stabilized his condition but also allowed him to resume his active lifestyle. This reflects a potential shift towards enhanced quality of life for patients, as newer generations of pacemakers promise to support greater activity levels and overall well-being.
Technological Advancements and Accessibility
While challenges remain—such as the current inability of wireless pacemakers to defibrillate or pace multiple chambers—the ongoing research and development in this field is promising. As production costs decrease and technology becomes more accessible, we can expect a wider adoption of these devices. The trend towards less invasive, more efficient cardiac interventions is poised to reshape how heart care is delivered.
A Future of Patient-Friendly Options
The trajectory of cardiac technology points towards minimal invasiveness and enhanced patient comfort. As wireless pacemakers progress, they are set to redefine standards within the cardiovascular landscape, promoting improved patient experiences and outcomes. The future of cardiac care will increasingly prioritize user-friendly, tailor-made solutions that address both medical needs and quality of life.
