A Study Of Deep Learning For Echo Analysis, Tracking, And Evaluation

April 15, 2026 updated by: Tim Poterucha, Mayo Clinic

DELINEATE-Deploy: Deep Learning for Echo Analysis, Tracking, and Evaluation - Prospective Deployment Platform IRB

The purpose of this study is to deploy and evaluate informational AI-Echo algorithms that assist echo clinicians in interpreting core echocardiographic parameters (e.g., LV/RV size and function, valvular disease severity) and stratifying disease progression risk. The primary outcome is clinician usability, interpretive consistency, and workflow integration. Second, we will conduct a pragmatic, stepped-wedge clinical trial with multiple arms evaluating diagnostic AI-Echo algorithms designed to identify specific cardiovascular diseases- such as genetic cardiomyopathy, ischemic heart disease, and cardiac amyloidosis-and assess whether AI deployment increases diagnostic testing and shortens time to diagnosis. Trials will be conducted using EHR-based notification systems with cluster-level randomization.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Clinicians who order, perform, and interpret echocardiograms and act on echocardiogram results, including both physicians and allied health staff taking care of patients aged ≥18 years.

Description

Inclusion criteria:

  • Genetic cardiomyopathy arm: Clinicians who order, perform, and interpret echocardiograms and act on echocardiogram results, including both physicians and allied health staff taking care of patients aged ≥18 years who are undergoing a comprehensive TTE at a participating Mayo Clinic site with AI-Echo analysis indicating high risk for a genetic cardiomyopathy. A high-risk score will be defined by a specific threshold determined in model development to maximize sensitivity while maintaining an adequate positive predictive value to support clinical deployment
  • Ischemic cardiomyopathy arm: Clinicians who order, perform, and interpret echocardiograms and act on echocardiogram results, including both physicians and allied health staff taking care of patients aged ≥18 years who are undergoing a comprehensive TTE with AI-Echo analysis indicating high risk for ischemic cardiomyopathy. A high-risk score will be defined by a specific threshold determined in model development to maximize sensitivity while maintaining an adequate positive predictive value to support clinical deployment.
  • Cardiac amyloidosis arm: Clinicians who order, perform, and interpret echocardiograms and act on echocardiogram results, including both physicians and allied health staff taking care of patients aged ≥18 years who are undergoing a comprehensive TTE with AI-Echo analysis indicating high risk for cardiac amyloidosis. A high-risk score will be defined by a specific threshold determined in model development to maximize sensitivity while maintaining an adequate positive predictive value to support clinical deployment.
  • Hypertrophic cardiomyopathy (HCM) arm: Clinicians who order, perform, and interpret echocardiograms and act on echocardiogram results, including both physicians and allied health staff caring for patients aged ≥18 years who are undergoing a comprehensive TTE at a participating Mayo Clinic site, with AI-Echo analysis indicating high risk for HCM. A high-risk score will be defined by a specific threshold determined during model development to maximize sensitivity while maintaining adequate positive predictive value for clinical deployment.

Exclusion criteria:

  • Genetic cardiomyopathy arm: Studies performed within the past 2 years at a Mayo site or in those patients with known or suspected diagnosis of genetic cardiomyopathy under evaluation, on hospice care, or who have an expected non-cardiac life expectancy <1 year, and patients who have opted out of institutional and state research authorizations.
  • Ischemic cardiomyopathy arm: Studies performed within the past 2 years at a Mayo site or in those patients with known CAD; prior myocardial infarction; revascularization with PCI or CABG; ischemic testing within the past 12 months; hospice care or expected non-cardiac life expectancy <1 year, and patients who have opted out of institutional and state research authorizations.
  • Cardiac amyloidosis arm: Studies performed within the past 2 years at a Mayo site or in those patients with prior amyloid-specific testing (e.g., technetium pyrophosphate scan, cardiac MRI with late gadolinium enhancement suggestive of amyloid) or biopsy-proven systemic amyloidosis, on hospice care, or have expected non-cardiac life expectancy <1 year, and patients who have opted out of institutional and state research authorizations.
  • Hypertrophic cardiomyopathy (HCM) arm: Studies performed within the past 2 years at a Mayo site or patients with a known diagnosis of HCM documented in the medical record prior to the index TTE, prior septal reduction therapy (surgical myectomy or alcohol septal ablation), or patients on hospice care or with an expected non-cardiac life expectancy <1 year, and patients who have opted out of institutional and state research authorizations.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of patients diagnosed with genetic cardiomyopathy confirmed by genetic testing
Time Frame: Baseline
Number of patients in the genetic cardiomyopathy arm who have a confirmed diagnosis of genetic cardiomyopathy based on genetic testing. Confirmation requires identification of a pathogenic or likely pathogenic variant in a cardiomyopathy-associated gene.
Baseline
Number of patients diagnosed with obstructive coronary artery disease
Time Frame: Baseline
Number of patients diagnosed with obstructive coronary artery disease in the ischemic cardiomyopathy arm, defined as ≥70% stenosis in any epicardial vessel, ≥50% in the left main coronary artery on coronary CTA or invasive angiography, or evidence of ≥3 ischemic myocardial segments on stress testing or high-risk perfusion features such as transient ischemic dilation.
Baseline
Number of patients diagnosed with cardiac amyloidosis
Time Frame: Baseline
Number of patients diagnosed with cardiac amyloidosis in the cardiac amyloidosis arm confirmed by consensus criteria, both imaging- and pathology-based amyloidosis diagnostic pathways.
Baseline
Number of patients diagnosed with hypertrophic cardiomyopathy
Time Frame: Baseline
Number of patients diagnosed with hypertrophic cardiomyopathy in the hypertrophic cardiomyopathy (HCM) arm according to standard guideline-based criteria (e.g., unexplained LV wall thickness ≥15 mm, or ≥13 mm in first-degree relatives, in the absence of other causes of hypertrophy).
Baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time from index TTE to confirmed diagnosis
Time Frame: Baseline
Time from index TTE to confirmed diagnosis of hypertrophic cardiomyopathy, cardiac amyloidosis, obstructive coronary artery disease, or genetic cardiomyopathy. Measured in days.
