Revolutionary Wireless System Offers New Hope for Patients with Cardiac Arrhythmias at St. David’s Medical Center
Austin, TX – July 21, 2025 – The Texas Institute for Heart Arrhythmias at St. David’s Medical Center is proud to announce a groundbreaking advancement in cardiac care, becoming the first facility in the United States to utilize a newly FDA-approved wireless system for the treatment of cardiac arrhythmias. This innovative technology promises a less invasive and more effective approach for patients suffering from irregular heartbeats.
The pioneering system, which has received the green light from the Food and Drug Administration (FDA), represents a significant leap forward in interventional cardiology. Traditionally, the treatment of cardiac arrhythmias, such as atrial fibrillation, often involved transvenous leads that extend from a pacemaker or implantable cardioverter-defibrillator (ICD) through blood vessels to the heart. While effective, these leads can sometimes be associated with complications.
The new wireless system, however, eliminates the need for these internal leads. Instead, a small, self-contained device is implanted directly within the heart muscle. This device communicates wirelessly with an external therapy system, allowing for precise and responsive treatment of irregular heart rhythms. This innovative design not only minimizes the potential for lead-related complications but also offers a more discreet and potentially more comfortable experience for patients.
Dr. Eleanor Vance, Director of the Texas Institute for Heart Arrhythmias, expressed her enthusiasm for this new treatment option. “We are thrilled to be at the forefront of introducing this revolutionary wireless system to patients in the United States,” said Dr. Vance. “This technology has the potential to significantly improve the quality of life for individuals living with cardiac arrhythmias by offering a safer, more efficient, and less intrusive treatment. Our commitment at St. David’s is to provide access to the most advanced and effective cardiac care available, and this new system aligns perfectly with that mission.”
The adoption of this FDA-approved wireless system underscores St. David’s Medical Center’s dedication to innovation and its role as a leader in cardiovascular medicine. The Texas Institute for Heart Arrhythmias is equipped with state-of-the-art facilities and a team of highly skilled cardiologists and electrophysiologists who are expertly trained to perform these advanced procedures.
Patients who are candidates for this new therapy will undergo a comprehensive evaluation to determine if it is the most suitable treatment option for their specific cardiac condition. The hospital anticipates that this wireless system will offer a valuable alternative for a wide range of patients, providing renewed hope and improved health outcomes.
