LAP during an echocardiographic ramped speed test in 3 patients. The trend of decreasing LAP when pump speed was increased can be seen. A value of zero indicates that pump speed is too high. The individual correlations between pump speed and LAP measured by the Titan sensor were significant (r = 0.92–0.99, p < 0.05). LAP, left atrial pressure.
