AI helps cardiologists terminate AFib for good with ablation
Artificial intelligence (AI) can improve atrial fibrillation (AFib) outcomes by providing real-time feedback during cardiac ablation procedures, according to new data presented at Heart Rhythm 2025, the Heart Rhythm Society’s annual meeting in San Diego.
The study’s focus was the effectiveness of DeePRISM, an advanced AI algorithm that helps cardiologists and electrophysiologists perform cardiac ablation in a way that maximizes the odds of achieving AFib termination.
DeePRISM was trained using data from 110 patients who presented for ablation due to persistent AFib. When testing the AI model, researchers found that it helped clinicians achieve acute AFib termination in 40% of ablation patients. The group added that the AI was associated with improved two-year outcomes, including freedom from recurrent AFib in up to 70% of patients.
“With the introduction of the DeePRISM model, we are taking a significant step forward in the treatment of persistent atrial fibrillation,” Chih-Min Liu, MD, PhD, a researcher with Taipei Veterans General Hospital in Taiwan, said in a statement. “Our study shows that AI-driven, real-time analysis not only enhances the success of the procedure but also ensures patient safety, marking a promising advance in electrophysiology.”
Heart Rhythm 2025 continues a long tradition
Heart Rhythm 2025 is the 46th annual meeting of the Heart Rhythm Society, which has said it received more than 3,400 scientific abstracts ahead of the show. Nearly 10,000 attendees are expected, including cardiologists, electrophysiologists, researchers, device manufacturers and many others.
“With the significant increase in both data submissions and attendee registration, this year’s meeting will highlight scientific advancements, discoveries, and real-world insights that electrophysiologists can apply to their daily clinical practice,” HRS President Ken Ellenbogen, MD, director of clinical cardiac electrophysiology at VCU Health, said in a statement ahead of the conference.
The Heart Rhythm Society stayed busy leading up to the conference, publishing detailed recommendations on how to develop AFib Centers of Excellence and when to consider same-day discharge after cardiac ablation.
