Compare/View screen
In playback, when viewing a TAVI/TAVR recording, the compare and view screens are available. The screen
highlights the differences between two recordings. In the table, the button
can be pressed and
change the gradients or regurgitation indices shown. The save button records a screenshot of the current
view which can be exported on an USB drive. When available, the DICOM export button takes a screen
capture which is sent to the PACS.
The View screen shows the same information and capabilities, but the layout is different. The removal of
the file selector allows more space to display the signal and the save and DICOM Export buttons are
available.
7.9.6
Playback Gradients and regurgitation indicators
For TAVI/TAVR recordings, the OptoMonitor 3 Display Unit can detect specific features in the signal which
is then used to calculate gradients and regurgitation indices. The physician can then validate if the
detection was made correctly before using the values.

LVEDP
: The left-ventricular end of diastolic position is used in the regurgitation indices. The
detected position is shown with a vertical dotted line between Ao and LV.
