Choose VX1+ if you need AI-powered software to assist electrophysiologists in the real-time identification and annotation of abnormal electrograms during cardiac ablation procedures. It provides valuable AI-driven insights and supports both manual and automatic annotation, aiding in precise targeting of dispersed electrograms.
View VX1+ →Volta Medical offers two AI-powered tools, Volta AF-Xplorer and VX1+, designed to assist electrophysiologists during cardiac ablation procedures for atrial fibrillation (AF) and atrial tachycardia (AT). Both systems aim to identify abnormal electrograms (EGMs) in real-time, which are believed to be drivers of these arrhythmias. They share core functionalities like real-time detection and annotation of dispersed EGMs, a color-coded dispersion indicator (red for highly dispersed, orange for dispersed, blue for non-dispersed), a “Booster Mode” for increased sensitivity during AT or slow AF, and cycle length estimation.
The key practical difference lies in their evolution and integration capabilities. Volta AF-Xplorer is presented as an enhanced version of the VX1 system (which VX1+ is also based on), offering improved workflow due to automated tagging of regions of interest, particularly with compatible mapping systems like Abbott’s EnSite X. It also boasts broader compatibility with various EP recording, 3D navigation systems, and mapping catheters. VX1+, while also providing real-time manual or automatic annotation of 3D maps, emphasizes its compatibility with existing 510(k)-cleared catheters and specific data acquisition systems.
For physicians prioritizing the latest advancements in workflow and broader system compatibility, Volta AF-Xplorer may be the more suitable choice, especially if utilizing the EnSite X mapping system for its automated tagging feature. Those already integrated with specific legacy systems like Boston Scientific LabSystem Pro or GE HealthCare MacLab CardioLab EP Recording System might find VX1+ a more direct fit, as it explicitly lists compatibility with these. Ultimately, both tools from Volta Medical aim to standardize the identification of dispersed EGMs to guide ablation procedures.

Head-to-Head
AI-generated assessment across six dimensions based on each tool's documented features and compliance posture. Grounded in public data — not a substitute for hands-on evaluation.
Usability
TieBoth Volta AF-Xplorer and VX1+ explicitly feature a 'Simple User Interface' and utilize color-coding (red, orange, blue) to indicate electrogram dispersion levels. They also both include a 'Booster Mode' to enhance software sensitivity, suggesting a comparable user experience across key operational aspects.
Clinical Value
Volta AF-XplorerVolta AF-Xplorer (and its successor AF-Xplorer II) references clinical evidence and a landmark randomized controlled trial (TAILORED-AF) published in Nature Medicine, indicating established clinical significance. In contrast, the FDA document for VX1+ explicitly states that its clinical significance for guiding catheter ablation has not been established by clinical investigations.
Pricing & Value
TieNeither Volta AF-Xplorer nor VX1+ provides publicly available pricing information, both requiring direct contact with the vendor. Without transparent pricing, it is impossible to conduct a head-to-head comparison of their respective value propositions based on cost.
Enterprise Readiness
Volta AF-XplorerVolta AF-Xplorer explicitly states 'yes' for BAA, HIPAA compliance, and FDA clearance, providing clear documentation of its adherence to critical regulatory and data security standards. While VX1+'s compliance is implied for a medical device, its documentation lacks these explicit affirmations, making Tool A appear more readily prepared for enterprise deployment.
Innovation
TieBoth tools are developed by Volta Medical and share core innovative functionalities, including real-time AI-assisted detection of dispersed electrograms and a 'Booster Mode.' While Volta AF-Xplorer II mentions advanced algorithms and a diversified database, the fundamental AI-driven approach to EGM analysis appears consistent across both products, making it difficult to distinguish a significant innovative lead for either based on the provided information.
Support & Docs
Volta AF-XplorerVolta AF-Xplorer's product page directly offers access to a 'User Manual' and 'Download Brochure,' indicating readily available support documentation. For VX1+, no explicit links to user manuals or dedicated support documentation were found in the provided facts or web searches, beyond regulatory filings.
