0.733
C-index for Outcome Prediction
ML algorithms incorporating PALS refine DD classification, outperforming traditional guidelines in predicting outcomes (C-index 0.733 vs. 0.720) and improving diagnostic clarity in indeterminate cases with novel parameters like LA strain index.
AI's Impact on Aortic Stenosis Management
Scenario: A large multi-center study utilized AI to detect severe Aortic Stenosis (AS) and predict patient outcomes. The AI model, trained on over a million echocardiograms, identified high-risk individuals with 5-year mortality (67.9%) even when they didn't meet traditional guideline-defined thresholds.
Challenge: Traditional AS diagnosis and risk stratification often miss high-risk patients and lack personalized follow-up schedules, leading to suboptimal outcomes.
Solution: The AI decision-support algorithm achieved an AUROC of 0.986 in detecting severe AS, allowing for earlier detection and improved risk stratification comparable to conventional methods. It enables tailored follow-up schedules based on individual echocardiograms.
Impact: AI significantly improves decision-making, patient selection for TAVR planning, and can guide personalized management, leading to better patient outcomes and resource optimization.
| Feature | Traditional Risk Scores | AI-based Risk Score (EuroSMR) |
|---|---|---|
| Parameters Incorporated | Limited (clinical) | 18 (clinical, echo, lab, meds) |
| Extreme Risk Patient ID (Mortality >70%) | Lower Accuracy | AUC 0.789 |
| Treatment Futility Identification | Limited | Enhanced for M-TEER |
| Explainability (SHAP) | No | Yes (NT-proBNP, NYHA, TAPSE) |
AI models enhance MR risk stratification by incorporating a wider range of parameters, identifying extreme risk patients with higher accuracy, and aiding in treatment planning (e.g., M-TEER).
