5 min Neurovascular Impact Continues to Expand

Our latest blog focuses on the expansion of the neurovascular platforms with articles on the latest data from ISC 2022, expansion of the platform with Viz ANEURYSM and Viz SDH (510k pending) and new partnerships.

AI in the stroke workflow continues to make a significant impact on stroke through the intelligent care platform in combination with Viz LVO, Viz CTP, and Viz ICH modules.  The combination of Al powered alerts, a high fidelity mobile image viewer with pre-PACS timing and a HIPAA compliant communication tool, Viz LVO has powered the stroke workflow reducing Door to Treatment from 202 minutes to under 60, as supported by multiple publications.1-7

New data further validates the impact of

Four posters and one oral abstract presented at ISC22 focused on results with Viz.  Highlights include new data from UCSD in the VISIION study7, where DTG times improved by 32% (41 min) in direct patients with LVO. The University of Ohio (Wexner) presented a poster further supporting the accuracy of ICH where 82 of 83 patients were detected.8 An oral abstract by the same institution further supported the sensitivity and specificity of Viz LVO in the real world.9

Two posters further validated the accuracy of Viz CTP.  A poster by Atrium Health compared the Hypointensity Ratio (HIR) of Viz to Rapid and found the agreement in “Moderate to very good range” by Intraclass Correlation Coefficient (ICC) standards.10  Another poster abstract by University of Cincinnati highlighted “no difference in EVT eligibility using Viz or Rapid when both DEFUSE3/DAWN criteria were considered.”11

For more detail on the VISIION study, view the poster presentation by Morgan E Figurelle, DO, lead author of the poster abstract, in the video below or link to the poster abstract.

A well-attended Learning Studio on The Impact of AI on Stroke Care was hosted by Dr. Ameer Hassan from Valley Baptist in south Texas where he presented his Viz experience in a 13 hospital network. Dr. Hassan shares his published data in DIDO, DTG, patient outcomes and access to care.5,12,13

Neurovascular News and Announcements

Aneurysm Receives FDA 510(k) Clearance for Viz ANEURYSM

We’re excited to announce our latest clearance, Viz ANEURYSM. A first-of-its-kind population health tool that uses AI to automatically detect suspected cerebral aneurysms and standardize workflow across the health system. The combination of detection with an ability to schedule patients for neurovascular specialist follow-up is an important advancement for aneurysm patients to help improve outcomes.

Subdural Hemorrhage

We are proud to announce that Viz SDH has also been submitted for 510(k) approval

Viz SDH was initially developed as a tool within Viz RECRUIT to assist with trials for SDH. Viz SDH is offered as an investigational device with the Medtronic EMBOLISE trial for the endovascular treatment of subdural hematomas. Investigational use only. Not for sale in the US.

The SDH algorithm has been submitted to FDA and is now 510(k) pending. Once approved, the software can be used outside of a trial. 510(k) Pending. Not for sale in the United States.


Expanding access to through TeleSpecialists

Partner hospitals of TeleSpecialists and will be able to integrate the platform into the TeleSpecialists telecare platform for a more seamless and integrated workflow experience. View the press release to learn more.

Best Practices for Stroke Coordinators

If you’re a stroke coordinator, you don’t want to miss the best practice discussion moderated by our very own Daniel D’Amour, MBA, RN, CEN, SCRN. In 10 minutes, Daniel shares nationwide examples of changes to workflow that have positively impacted time to treatment. He’s joined by Erin Cekovich, BSN, SCRN, ASC and Cesar Velasco, BSN, RN, SCRN, ASC from PennState Health.
