AI-Enabled Precision Echocardiography: Toward Personalized Cardiovascular Care

  Figure 1. From Population-Derived to Patient-Specific Cardiovascular Assessment. This figure compares and contrasts traditional echocardiography with precision echocardiography (AI-enabled). Traditional echocardiography looks at individual patients in relation to population-derived reference values, resulting in binary normal/abnormal classification that can miss subclinical disease and individual variability. Precision echocardiography uses AI to establish patient-specific baselines, extract comprehensive phenotypic features beyond conventional metrics, model individual trajectories over time, and generate personalized risk profiles that enable earlier detection and targeted interventions.

  Figure 2. AI Workflow in Clinical Practice Echocardiography. An AI-enabled precision echocardiography workflow can integrate into clinical practice through four sequential steps. In Step 1 (Input), patient clinical data and echocardiographic images are acquired using standard protocols. In Step 2 (AI Processing), automated quality assessment, view classification, and measurement extraction are followed by advanced analytics including phenotyping algorithms, risk prediction models, and multimodal data integration, extracting more than 100 quantitative features beyond human perceptual capacity. In Step 3 (Clinical Decision Support), AI generates phenotype assignments that identify disease subtypes and mechanisms, personalized risk scores that predict outcomes, and treatment guidance recommending therapies with the highest likelihood of benefit. In Step 4 (Personalized Management), clinicians implement phenotype-guided therapy selection, risk-stratified monitoring schedules, and longitudinal trajectory tracking for early change detection. This workflow can transform echocardiography from descriptive imaging into a precision diagnostic and therapeutic decision-support tool.

  Figure 3. Proposed Practical Implementation Roadmap. Implementation of precision echocardiography requires a phased approach with attention to technical, clinical, economic, and equity barriers. Phase 1 focuses on pilot testing with local validation and workflow establishment. Phase 2 integrates AI into clinical systems with decision support and outcome monitoring. Phase 3 expands to additional applications and scales across populations.
