Interventional Centers
Interventional Centers: Evaluate the Door-In to Groin Puncture time for subjects in which Viz was utilized versus standard of care.
Time of subject presentation through up to 90 days post treatment.
Secondary Outcomes (1)
Workflow Endpoints
Time of subject presentation through up to 90 days post treatment.
Study Arms (2)
Non-Interventional Centers
Cohort A: Viz Subjects Initially Presenting to a Non-Interventional Center The group will be comprised of subjects randomized to Viz and who initially present to a non- interventional center. Cohort B: Subjects Initially Presenting to a Non-Interventional Center The standard of care group will be comprised of subjects randomized to not have Viz notification and who initially present to a non-interventional center.
Interventional Centers
Cohort C: Viz Subjects Initially Presenting to an Interventional Center The group will be comprised of subjects randomized to Viz and who initially present to a interventional center. Cohort D: Subjects Initially Presenting to a Interventional Center The standard of group will be comprised of subjects randomized to not have Viz notification and who initially present to an interventional center.
Interventions
Viz uses artificial intelligence to automatically detect, triage and notify stroke specialists of suspected large vessel occlusion (LVOs) and computed tomography angiogram (CTA) imaging. Viz includes functionality to automatically process computed tomography perfusion (CTP) images. Additionally, Viz includes a mobile non-diagnostic image viewer and HIPAA-compliant secure messaging.
Eligibility Criteria
Subjects with an identified LVO per Viz will be eligible for the study.
You may qualify if:
- Age of 18 years or greater.
- Signs and symptoms consistent with the diagnosis of a stroke.
- Stroke protocol imaging (CTA) with a confirmed presence of anterior LVO via Viz.
You may not qualify if:
- Poor or incomplete CTA imaging data.
- Disagreement between neuroradiologist and stroke specialist or neurointerventionalist relative to presence of a stroke.
- Other serious, advanced, or terminal illness (investigator judgment) requiring treatment that significantly delays initiating transfer and/or treatment for stroke.
