FORT MILL, S.C., April 13, 2026 (GLOBE NEWSWIRE) -- Catheter Precision, Inc. (NYSE:VTAK) ("VTAK" or the "Company") today announced that the results of a recently concluded VIVO study have been accepted in EP Europace, the leading European electrophysiology journal.

The EP Europace journal provides an avenue of communication for top-quality European and international original, scientific work and reviews in the fields of arrhythmias, pacing and cellular electrophysiology. The journal offers readers a collection of contemporary, original, peer-reviewed papers, invited papers and editorial comments, together with book reviews and correspondence.

The accepted manuscript titled "Accuracy of a non-invasive electrocardiographic imaging system in scar-dependent ventricular tachycardia: Relationship to arrhythmogenic substrate and imaging defined scar" highlights the feasibility of VIVO for scar-related ventricular tachycardia (VT) was led by Professor Tarv Dhanjal, MBChB(hons) PhD FRCP FESC FEHRA, Professor of Cardiology (University of Warwick). This study included 31 patients and mapped 48 VTs with VIVO and standard of care electroanatomical mapping systems to determine accuracy. The study concluded that ECGi mapping with VIVO can accurately predict the arrhythmogenic substrate for scar-dependent VT and incorporation of ECGi mapping to conventional VT ablation workflows may improve procedural efficiency.

Of additional importance, this study compares VIVO's predictability of epicardial VTs to a four step ECG based algorithm. In patients with Non-ischemic cardiomyopathy (NICM), the VIVO localization had a 100% specificity and 66.7% sensitivity, while a traditional four-step ECG-based algorithm had a sensitivity and specificity of 50% and 0%, further demonstrating VIVO's capabilities to improve procedural workflow.David Jenkins, CEO of Catheter Precision, says, "This study demonstrates that VIVO works in a wide range of patients, including those with scar related ventricular tachycardia and that it can improve procedural workflow and reduce procedure time even in very difficult procedures like epicardial VT. We are very pleased with the outcomes of this study and plan to start a larger, multi-center study later this year to prove out these results on a larger scale."
