Combination Mode Measurements
Some cardiac calculations, such as Aortic Valve Area and Left
Ventricle Stroke Volume, require you to make measurements in
more than one mode. This section includes those
measurements, organized by the region of interest. You can find
the descriptions of how to perform these measurements
elsewhere in this chapter.
Aortic Valve
One distance and
two peak velocity
measurement
• Aortic Valve Area (Ao Diam, LVOT Vmax, AV Vmax)
• Aortic Valve Area by Continuity Equation by Peak Velocity
(Ao Diam, LVOT Vmax, AV Vmax)
Velocity flow trace
and one trace
measurement
• Stroke Volume by Aortic Flow (AVA Planimetry, AV Trace)
Velocity flow trace,
one trace, and one
time interval
measurement
• Cardiac Output by Aortic Flow (AVA Planimetry, AV Trace,
HR)
Two velocity flow trace and one distance measurement:
• Aortic Valve Area by Continuity Equation VTI (Ao Diam,
LVOT Vmax, AV Trace)
