NCT06600256

Brief Summary

This is a prospective, open-label, multi-center workflow pilot. Viz HCM will be implemented at each participating site and all conforming incoming ECG recordings within a 6-month enrollment period will be analyzed using Viz HCM. This workflow pilot provides an opportunity to understand how Viz HCM will be utilized and adopted post-market and to learn the pre- versus post-implementation impact of Viz HCM on HCM clinical workflow. This pilot is designed to evaluate the implementation of Viz HCM for use in traditional HCM clinical workflow. Findings from this pilot will help inform the following:

  • The impact of Viz HCM on HCM clinical workflow
  • How Viz HCM will be utilized and adopted post-market
  • The diversity in the HCM patient population and the variation in HCM clinical workflow

Outcome Measures

Primary Outcomes (2)

  • Percentage of Viz suspected HCM cases viewed by users

    Algorithm performance - sensitivity and specificity of the Viz HCM software

    up to 10 minutes

  • Number of viewed Viz suspected HCM cases that receive any follow-up action (e.g., schedule test, physician referral)

    algorithm processing time

    up to 10 minutes

Secondary Outcomes (2)

  • Number of HCM diagnosed patients (based on hospital records over the 6 months prior to site activation) [pre-Viz]

    up to 10 minutes

  • Number of HCM patients (flagged by Viz HCM and confirmed by follow-up transthoracic ECHO and/or CMR diagnostic imaging) [post-Viz]

    up to 10 minutes

Other Outcomes (4)

  • Type, date, and number of follow-up tests after HCM notification

    180 days

  • Time from HCM notification view to follow-up testing and/or documented diagnosis

    up to 48 hours

  • User satisfaction (Viz HCM Physician Satisfaction Survey)

    180 days

  • +1 more other outcomes

Study Arms (2)

pre-Viz

The number of HCM diagnosed patients (based on hospital records over the 6 months prior to site activation with the Viz HCM software) \[pre-Viz\]

Behavioral: Baseline Effectiveness Cohort

post-Viz

The number of HCM patients (flagged by Viz HCM and confirmed by follow-up transthoracic ECHO and/or CMR diagnostic imaging) after site activation with the Viz HCM software \[post-Viz\]

Behavioral: Viz HCM ECG Review

Interventions

Viz HCM will auto-alert relevant users to ECGs the algorithm has deemed as suspicious for HCM. Following review of this alert and the patient\'s Medical/Clinical History, the reviewer will take the next Standard of Care action they deem appropriate.

post-Viz

A review of the timing and clinical details of the diagnostic process for patients diagnosed with HCM before the site began using Viz HCM.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

During the 6-month enrollment period, patients who receive an ECG at participating sites will be screened to determine if they meet eligibility criteria. All patients meeting eligibility criteria will be enrolled

You may qualify if:

  • Patients aged 18 years of greater at the time of arrival to healthcare facility
  • Patients underwent resting 12-lead digital electrocardiogram (ECG) at healthcare facility

You may not qualify if:

  • Patients with poor or incomplete recordings
