To calculate the Aortic Valve Area (AVA)
The AVA calculation requires a measurement in 2D and two measurements in Doppler. After the
measurements are saved, the result appears in the patient report.

Even after completing the trace, you can still adjust it by dragging the cursor
backward on the dotted line.
The recommended method is to trace from annulus to annulus and allow the
system to automatically close the trace. If the start and end trace points are too
close together, the centerline adjustment function may be limited.
