Questions and Correct Answers
Which of the following is preferred to document motion of the disk in a St. Jude Valve?
A) M-Mode
B) PW Doppler
C) Color doppler
D) CW doppler ✅M-Mode-used to document the motion of the ball/disk in a
mechanical valve. Doppler is used to assess flow through the valve.;All velocity and
time interval measurements should be performed at a sweep speed of ____________
or greater. ✅100 mm/s;How would an optimal apical view look? ✅1. LV cavity is an
ellipsoid shape
2. Image should consist of about 2/3 LV and 1/3 LA
3. All four chambers demonstrated on image;What is the appropriate method for using
doppler to evaluate suspected aortic stenosis in a patient with afib? ✅Never record
peak velocities from the waveform obtained after a long R-R interval;Why is the hepatic
vein more commonly evaluated with doppler to assess venous inflow into the right
atrium than the IVC? ✅The flow in the hepatic veins is parallel to the ultrasound beam
which provides a better doppler signal;M-Mode evaluation of the RV free wall motion is
most important in which condition? ✅Large pericardial effusion;Left ventricular ejection
time is measure on the m-mode tracing of the _______________. ✅Aortic valve;When
evaluating the aortic arch in the suprasternal notch view, how do you manipulate the
transducer to image the superior vena cava? ✅Scan rightward with a slight anterior
angulation;Stress echocardiography is most helpful in the assessment of suspected
________________. ✅Coronary artery disease;What would cause an incorrect
assessment of the mitral valve area using the pressure half time measurement?
✅Significant aortic regurgitation;You are evaluating a patient with an EF of 33% for
diastolic dysfunction. The left atrial volume index and tissue doppler measurements are
recorded. The exam is suboptimal for documenting an accurate TR velocity. What other
parameter is recommended to aid in diagnosis of diastolic dysfunction in this patient?
✅S/D ratio of the pulmonary veins;Why is the subcostal view performed as part of the
protocol for a standard echo exam? ✅To assess right atrial pressure;The standard
Simpson method calculates the EF% by tracing ESV and EDV of the LV during what
two views? ✅Apical 4 and 2;________________ is a type of vasodilator that
decreases venous return to the heart and exacerbates mitral valve prolapse. ✅Amyl
nitrite;When measuring left atrial volume: ✅LA length is measured from the center of
the mitral annulus to the inner edge of the posterior wall;A sonographer should instruct
the patient on the use of the Borg scale during: ✅Stress Echo: used to indicate the
level of breathlessness during exercise;How do you measure the strain rate for a
specific segment of the LV wall? ✅Take 2-3 tissue doppler samples from the area of
interest;The first image on an echo should be taken at increased depth to exclude:
✅Pericardial and pleural effusion;How should the LVOT diameter be measured? ✅3-
, 10 mm from the aortic valve insertion points;What 2 D echocardiography views can be
used to diagnose MVP? ✅PLAX;During evaluation of a possible PFO with saline
contrast, when do you start counting heartbeats to determine when the shunt flow
occurs? ✅Begin counting beats once the contrast opacifies the right atrium;To
evaluate the _____________________ from the standard apical 4 chamber view, depth
should be adjusted to view 2 cm behind the atria. ✅Pulmonary veins;What is the most
reliable method for diagnosing cardiac tamponade? ✅Doppler evaluation of mitral
inflow velocities during normal respiration;How do you manipulate the transducer from
the parasternal long axis view of the left heart to visualize the parasternal short axis
view? ✅90 degree clockwise rotation;3D echocardiography would be most beneficial in
an adult patient with: ✅An atrial septal defect;If the aortic velocity is 4 cm/s and the
systemic BP is 120/80, what is the peak LV pressure? ✅184 mmHg
4(4)^2=64+120=184 mmHg;Aside from the evaluation of coronary artery disease, stress
echo can be helpful in the evaluation of: ✅1. Aortic valve gradient and area in calcific
aortic stenosis
2. MR severity in myxomatous mitral valve disease
3. Pulmonary pressures in mitral stenosis or regurgitation
4. Aortic coarctation pressure gradients
Dynamic outflow obstruction in HCM;A 16 year old presents for an echo due to a
continuous murmur. The echo demonstrates left ventricular volume overload and an
area of turbulent flow in the left pulmonary artery throughout the cardiac cycle. What
supplemental view should be performed to better evaluate this patient? ✅High
parasternal axis-you should expect a patent ductus arteriosus due to continuous
murmur;A 66 year old male patient presents for a TEE with a history of severe mitral
stenosis. The chart shows severe MS was documented one month ago on a
semiannual TTE exam. There are also notes that he is scheduled for a
commissurotomy in 2 days. What is the primary purpose for today's exam? ✅To rule
out left atrial thrombus-the risk of embolization is very high during or after the procedure
if thrombus is present and the procedures would be contraindicated.;What abnormality
is demonstrated using saline contrast while performing the parasternal long axis view of
the heart? ✅Persistent left SVC;What is the most commonly performed method of
estimating the mitral valve area? ✅Pressure half time;What are some characteristics of
measuring stroke volume? ✅1. Calipers are placed just proximal to the aortic valve,
from the white-black edge of the septal endocardium to the black-white edge of the
anterior mitral leaflet
2. PW doppler is used to obtain the velocity curve from the apical window
3. Standard location for SV measurement is in the LVOT at the level of the aortic
annulus just proximal to the valve leaflets;Color scale settings should be set with a
maximum velocity between _______________ cm/s for the routine echo exam. ✅50
and 70;When estimating the regurgitant volume of MR, the radius of the jet on the
ventricle side of the valve, the velocity time integral of the mitral regurgitation and
____________________ are required. ✅Peak velocity of mitral regurgitation;What is
the appropriate method for using doppler to evaluate suspected mitral stenosis in a
patient with atrial fibrillation? ✅Average the peak velocity and pressure half time
