  Figure 2. Correlation (A) and Bland-Altman (C) analyses for the mean arterial pressure (MAP) time-domain results presented in Figure 1 for transcatheter aortic valve replacement (TAVR) for patient 2. Panel B presents the count distribution of the Bland-Altman plot. Correlation (D) and Bland-Altman (F) analyses for the heart rate (HRT) time-domain results presented in Figure 1 for TAVR for patient 2. Panel E presents the count distribution of the Bland-Altman plot.

  Figure 3. Correlation (A) and Bland-Altman (C) analyses for heart rate (HRT) for all four transcatheter aortic valve replacement (TAVR) patients. Panel B presents the count distribution of the Bland-Altman plot. Correlation (D) and Bland-Altman (F) analyses for mean arterial pressure (MAP) for all four TAVR patients. Panel E presents the count distribution of the Bland-Altman plot.

  Figure 4. Extracted risetimes for transcatheter aortic valve replacement (TAVR) for patient 1. Top panel (A): Front rise time, in seconds, of the arterial peak. Indicated in this panel by the red lines are the pre- TAVR and post-TAVR deployment time windows used for calculating differences. Center panel (B): Rise time, in seconds, from the onset of the peak to the highest slope point of the front of the pulse. Bottom panel (C): event log, where the stars indicate the time location of the labelled events.

Center panel (B): Rise time, in seconds, from the onset of the peak to the highest slope point of the front of the pulse.
