Four abstracts with clinical data supporting use of Catheter Precision’s VIVO™ technology accepted for presentation at leading electrophysiology conference

Ra Medical Systems, Inc. (NYSE American: RMED) (Ra Medical), a medical device and technology company focused on cardiac electrophysiology, announces that four abstracts with clinical data supporting its VIVO technology have been accepted for presentation at the European Heart Rhythm Association Congress (EHRA 2023) being held April 16-18, 2023 in Barcelona. VIVO, developed by Ra Medical’s wholly owned subsidiary Catheter Precision, is a proprietary AI system used to non-invasively identify the origin of ventricular arrhythmias prior to an ablation procedure.

“It is highly gratifying to present clinical data to the many electrophysiology thought leaders at the largest European meeting solely focused on arrhythmia management and treatment,” said David Jenkins, Ra Medical Executive Chairman. “All four abstracts with VIVO clinical data submitted by leading physicians to the Congress were accepted for presentation following an extensive peer-review process. To have one-hundred percent acceptance of submitted abstracts is rare and I believe indicative of the positive impact VIVO is having on ventricular ablation procedures. We view this recognition as a major milestone in gaining clinical acceptance by both EP thought leaders and the larger medical community.”

Ra Medical plans to issue a press release with clinical data from the abstract following presentations at EHRA 2023.
