Vektor Medical Announces Post-Market Study Evaluating Benefit of AI-Powered Analysis to Identify and Ablate Non-Pulmonary Vein AF Targets
"The IMPRoVED-AF trial represents a landmark moment for Vektor, validating vMap's clinical efficacy and demonstrating our ability to dramatically improve outcomes and redefine arrhythmia care." Rob Krummen, CEO, Vektor Medical
IMPRoVED AF (artificial Intelligence Mapping and ablation of non-PulmonaRy Vein Electrical Drivers of AF) is a prospective, randomized, controlled, multi-center study clinical trial that will rigorously compare clinical outcomes in patients undergoing pulmonary vein isolation (PVI) alone versus PVI and additional driver ablation guided by Vektor's proprietary vMap technology. vMap is the only FDA-cleared non-invasive AI-powered arrhythmia analysis technology designed to improve, enhance, and accelerate ablation procedures, utilizing data from a standard 12-lead ECG.
'Persistent and recurrent AF remains incredibly challenging, profoundly affecting patient quality of life and burdening our healthcare systems,' said Dr. Gery Tomassoni, Principal Investigator and cardiac electrophysiologist at Baptist Health Lexington. 'The IMPRoVED AF study is positioned to address this challenge. By leveraging AI-driven technology, we aim to significantly enhance ablation accuracy and effectiveness, potentially redefining the standard for managing persistent AF.'
The study, managed by clinical research organization Veranex, will enroll up to 384 patients with persistent (not longstanding) and recurrent AF at 15 electrophysiology centers across the United States and Europe. The study's design specifically aims to demonstrate the comparative clinical benefit of utilizing AI-driven mapping to identify and ablate non-pulmonary vein electrical hotspots in accordance with standard-of-care ablation practices.
The primary endpoint of the study is freedom from AF on or off antiarrhythmic drugs at 12 months.
Additional secondary endpoints include:
freedom from AF and atrial tachycardia on and off antiarrhythmic drugs at 12 months
total procedure time
total vMap mapping time
AF burden as a proportion of time before versus after ablation
proportion of subjects with AF terminated spontaneously upon and after the first ablation, and total fluoroscopy dose.
Interim results are anticipated by HRS 2026; comprehensive results are expected at HRS 2027.
'EPs can't ablate what they can't identify. That's exactly why vMap was created - to empower EPs with actionable insights previously inaccessible from a standard ECG,' said Rob Krummen, CEO of Vektor Medical. 'The IMPRoVED AF trial represents a landmark moment for Vektor, validating vMap's clinical efficacy and demonstrating our ability to dramatically improve outcomes and redefine arrhythmia care. Re-do procedures have unfortunately become the norm, underscoring the critical need for technologies that provide additional insight on arrhythmia sources.'
In parallel with the IMPRoVED AF study, Vektor has also initiated the VITAL-EP registry to collect real-world data on the clinical utility, safety, and procedural efficiency of vMap-guided ablation procedures. The registry, managed by clinical research organization Heart Rhythm Clinical and Research Solutions, aims to enroll at least 110 patients across four sites. The registry will evaluate multiple procedural-related endpoints, including AF termination or AF non-inducibility in AF ablation cases and procedure efficiency, including procedure duration and fluoroscopy use.
About vMap ®
vMap is the only FDA-cleared, non-invasive AI-based solution for mapping arrhythmias, utilizing just a 12-lead ECG. vMap localizes arrhythmia sources for focal and fibrillation-type arrhythmias, including atrial fibrillation. By unlocking actionable insights contained within a standard 12-lead ECG, vMap enables physicians to rapidly and accurately locate arrhythmia source locations. Backed by extensive clinical evidence, vMap not only improves patient outcomes but also reduces procedure time, optimizing workflow across the entire arrhythmia care pathway.

Artisanal bread sold at Kroger, Walmart voluntarily recalled
Hartford Bakery is voluntarily recalling hundreds of loaves of one of its artisanal breads because the products may contain undeclared hazelnuts, the U.S. Food & Drug Administration (FDA) said. Out of an abundance of caution, the company, headquartered in West Hartford, Connecticut, issued a recall for its 'Lewis Bake Shop Artisan Style 1/2 Loaf' on July 10, according to the FDA. The company warns that "people with a nut allergy or severe sensitivity to hazelnuts run the risk of serious or life-threatening allergic reactions" if they consume the bread. Hartford Bakery said it had removed all products linked to the six affected production lots. The recalled bread was distributed in Alabama, Arkansas, Georgia, Illinois, Indiana, Kentucky, Michigan, Mississippi, Missouri, Ohio, Tennessee and Wisconsin retailers, including Kroger and Walmart, according to the FDA. The FDA said there had been no major reports of injury or illness related to the recalled bread. "Hartford Bakery is aware of one customer who experienced digestive discomfort after consumption," the recall reads. "Hartford Bakery also received consumer complaints from those who saw the nuts before consuming the product." What does the recalled artisanal bread look like? The recalled bread comes in a flexible plastic bag marked with the following information: How was the undeclared allergen found? Hartford Bakery initiated the recall after finding that about 883 loaves of bread from six production lots contained visible hazelnuts and were distributed in 'Lewis Bake Shop Artisan Style 1/2 Loaf' packaging. Although the packaging reads "May Contain Tree Nuts," it does not say that it "Contains Hazelnuts." An investigation by the company revealed that an error in packaging led to the allergen being undeclared. Jonathan Limehouse covers breaking and trending news for USA TODAY. Reach him at JLimehouse@
