UC San Diego Health Implants World’s First Dual Chamber and Leadless Pacemaker System: A Revolutionary Treatment for Arrhythmias

UC San Diego Health Becomes First in Region to Perform Dual-Chamber, Leadless Pacemaker Implantation

In February 2024, UC San Diego Health achieved a significant milestone by implanting the world’s first dual chamber and leadless pacemaker system in San Diego. This innovative system aims to help individuals with irregular heart rhythms, known as arrhythmias, that can lead to complications like palpitations, fainting, and stroke.

Pacemakers and implantable cardioverter defibrillators (ICDs) are the standard treatments used to regulate irregular heartbeats. However, the new leadless pacemaker system offers a more minimally invasive option for patients by being placed in both chambers of the heart and utilizing novel communication technology. This advancement in technology opens up new possibilities for treating individuals with heart arrhythmias.

Atrial fibrillation is the most common type of arrhythmia, estimated to affect around 12.1 million people in the United States by 2030 according to the Centers for Disease Control and Prevention. Approved by the U.S. Food and Drug Administration (FDA) in July 2023, this new leadless pacemaker system provides a minimally invasive option for patients who require treatment for their irregular heartbeats.

Dr. Ulrika Birgersdotter-Green, a cardiologist and the director of pacemaker and ICD services at UC San Diego Health, highlighted the importance of having the option to use a leadless pacemaker system on both sides of the heart to treat more individuals living with heart arrhythmias. Nearly 80% of patients who receive a pacemaker require a dual chamber option, making this development significant in terms of providing a minimally invasive treatment option for these patients. While leadless pacemakers have been preferred by patients due to their minimal invasiveness compared to traditional pacemakers that require leads connected to an external generator or battery pack outside of the body, they were typically only available for individuals needing pacing on one side of the heart.

This recent development represents a significant step forward in the treatment of arrhythmias and offers new hope for patients in need of such interventions.

In summary, UC San Diego Health has successfully implanted the world’s first dual chamber and leadless pacemaker system in February 2024. This innovative system aims to help individuals with irregular heart rhythms by providing a more minimally invasive option for patients who require treatment for their irregular heartbeats compared to traditional treatments such as pacemakers or ICDs.

Approved by FDA in July 2023, this new technology provides an opportunity to treat nearly 80%
