Panel a Mitral Regurgitation. Panel b Aortic Stenosis. Area Under Curve (95% Confidence Interval) with shaded area around curve representing confidence interval. Red dashed line represents floor of performance as in the case of a hypothetical model making purely random predictions. Overall dataset size: 607,429 Echo-ECG pairs for 123,096 patients for Mitral Regurgitation. 617,338 Echo-ECG pairs for 128,628 patients for Aortic Stenosis.
