Accuracy of the HeartMate 3 (HM3) flow estimator calculated based on the static identification measurements. Left: Scatter plot of measured flow (Qmeas) versus estimated flow (Qest). Right: Bland-Altman plot showing the agreement between measurement and estimation by plotting the differences between Qmeas and Qest (y-axis) over the means of both signals (x-axis).
