UC San Diego Health Makes History with First Dual-Chamber Leadless Pacemaker System Implantation for Arrhythmia Patients.

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

In February 2024, UC San Diego Health made history by implanting the world’s first dual chamber and leadless pacemaker system in a patient. This innovative technology 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 development significant for those who need such interventions.

Leadless pacemakers have been preferred by patients due to their minimally invasive nature compared to traditional pacemakers that require leads or wires attached directly to the heart muscle or blood vessels. However, until now, 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 conclusion, UC San Diego Health has achieved a significant milestone by successfully implanting the world’s first dual chamber and leadless pacemaker system in San Diego. This innovative technology aims to help individuals with irregular heart rhythms that can lead to complications like palpitations, fainting
