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

UC San Diego Health recently made history by successfully 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.

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. Pacemakers and implantable cardioverter defibrillators (ICDs) are the standard treatments used to regulate irregular heartbeats.

Approved by the U.S. Food and Drug Administration (FDA) in July 2023, 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.

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 recent development an essential step forward in the treatment of arrhythmias. While leadless pacemakers have been preferred by patients, 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.

UC San Diego Health conducted the first implantation of the pacemaker system in a patient in February 2024. The successful implantation marks a major milestone in medical technology and opens up new possibilities for treating individuals with heart arrhythmias.

In conclusion, this innovative dual chamber and leadless pacemaker system is an excellent example of how advances in medical technology can improve patient outcomes and provide new hope for those living with chronic conditions like atrial fibrillation. With further research and development, this technology has the potential to revolutionize the way we treat arrhythmias and improve overall health outcomes for millions of people around
