Question Set 6 Flashcards
How does Simpson’s biplane measurements calculate a volume?
By calculating volumes as a sum of a series of parallel ‘slices’ from top to bottom of a structure
Normal colour doppler flow moving from LV through the LVOT, the AoV, SoV, and out the AO in AP4 view would appear as… ?
Mostly blue with potentially a small amount of aliasing
What would be the benefit to having a larger colour doppler box which covers multiple structures?
Catching unexpected pathology for further investigation
What measurement is the ASE recommended RA size quantification?
RA volume
What layer of heart are you tracing along when completing a ventricular Simpson’s biplane measurements?
endocardium
TAPSE measurements usually begin at what part of the ECG?
R wave
In AP4 your Simpson’s biplane measurement length line of the LV comes to 9.8cm, in AP2 your length line of the LV comes to 7.2cm. Were your AP4 and AP2 measurements most likely measured in the same plane?
No, there is a difference greater than 10% between the two numbers
What view is most optimal for assessing RV1/RVIDd?
Modified AP4
RV Fractional Area Change can be thought of most similarly as what?
RV EF
After completing an echo on a male patient you notice an LA volume of 49 ml/m^2, how would you classify this?
Severely enlarged
What does TAPSE stand for?
Tricuspid annular plane systolic excursion
Which measurement evaluates the length between superior portion of the RA to the inferior portion of the RA?
Major
When completing the LA volume measurement, your length line between AP4 and AP2 should vary by how much?
< 5mm
What two planes does one utilize when calculating an EF from a Simpson’s Biplane measurement?
AP4 and AP2
After completing an echo on a female patient, you notice a RVD1, RVIDd measurement of 4.6cm, how would this be classified?
Abnormal, enlarged
