nameTricuspid valve Effective regurgitant orifice area by US.doppler+Calculated by PISA method
descriptionThe effective regurgitant orifice area (EROA) is the size of the defect where the valve leaflets are not aligning normally (coaptation defect). The severity of regurgitation is related to the EROA. EROA can be calculated by the Volumetric method as regurgitant volume divided by the velocity time integral of the regurgitant jet velocity (VTIRegJet), which is recorded by continuous wave Doppler.

timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemTricuspid valve
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
