SOLUTIONS
What valve separates the areas of greatest pressure differences? Correct Answer: Mitral valve
What valve separates the areas of the lowest pressure differences? Correct Answer: Tricuspid
valve
Where does the LAD lie on the heart? Correct Answer: Anterior interventricular groove (sulcus)
What aortic cusp is superior in PLAX view? Correct Answer: RCC
What aortic cusp is posterior in PLAX view? Correct Answer: NCC
From the left parasternal window which of the following are you most likely to get accurate
velocity measurments? Correct Answer: Pulmonary artery
What view gives the most accurate velocities of the PV/pulmonary artery? Correct Answer:
PSAX; short axis
What is the red flow traveling to the RA that you can sometimes see from the inflow view?
Correct Answer: IVC
What are the tricuspid leaflets seen in the inflow view? Correct Answer: anterior and posterior
Where is the LAA located on TTE? Correct Answer: Sometimes can be seen in AV level short
axis, but is better visualized in an apical 2 chamber view
The coronary arteries come off the: Correct Answer: Sinuses of Valsalva
What is the most anomalous artery? Correct Answer: Right coronary
During which phase do the coronaries fill? Correct Answer: early diastole
True/False --- The coronary arteries can fill during systole Correct Answer: False
When is TAPSE measured? Correct Answer: Between end diastole and peak systole
This is the transition between the sinuses of Valsalva and the tubular portion of the ascending
aorta Correct Answer: STJ (sinotubular junction)
What can sometimes be seen below the RPA in a SSN view? Correct Answer: Left atrium
The best images of the ascending aorta are often obtained from which transducer window?
Correct Answer: suprasternal
,Name the vessels coming off the arch and most proximal or distal. Correct Answer: Innominate
(proximal), left carotid and left subclavian (distal)
What cardiac pathology is associated with bicuspid aortic valves? Correct Answer: Coarctation
of the aorta
Which window do you use to look for the secondary finding in bicuspid valves? Correct Answer:
Suprasternal arch; suprasternal notch
Where do most aortic coarctations occur? Correct Answer: aortic isthmus
How can we specifically identify the location of an aortic isthmus? Correct Answer: After the
take-off of the left subclavian artery
Where are the pulmonary veins located? Where are they best visualized? Correct Answer: Feed
into the LA and are best visualized in 4 chamber
What pulmonary veins are viewed in apical 4 chamber? Correct Answer: Lower pulmonary
veins
What pulmonary veins are viewed in apical 5 chamber? Correct Answer: Upper pulmonary
veins
From the apical 4 chamber view how do you rotate the transducer to obtain the apical LAX?
Correct Answer: clockwise 120 degrees
Where is the coronary sinus located? Correct Answer: posterior AV groove
Which view do you use to evaluate the coronary sinus? Correct Answer: PLAX
To visualize the coronary sinus in the apical 4 chamber view you should tilt the transducer:
Correct Answer: posterior
Which valve sits at the opening of the coronary sinus? Correct Answer: Thebesian
What valve sits at the opening of the IVC? Correct Answer: Eustachian
Where is the Chiari network located? Correct Answer: Right atrium
What portion of the pulmonary venous PW Doppler represents atrial systole? Correct Answer: A
wave
At what temperature is it unsafe to use a TEE probe? Correct Answer: 40-45 degrees celcius
(Above 41 degrees celcius)
Which electrical pathway has the fastest intrinsic rate? Correct Answer: SA node
, What is the absolute refractory state? Correct Answer: period when a muscle cell is not
excitable; occurs from phase 1 into phase 3
What is a normal duration for the QRS complex? Correct Answer: 0.10 sec or 100 msec
This is known as the rubber band theory Correct Answer: Frank Starling Law
What occurs during preload? Correct Answer: Filling
What is occuring during afterload? Correct Answer: Resistance to eject blood out
Echo findings for preload: Correct Answer: dilatation
Echo findings for afterload: Correct Answer: hypertrophy
Which study does not allow for the calculation of ejection fraction? Correct Answer: Chest x-
ray
How do you eliminate aliasing on PW spectral doppler? Correct Answer: Switch to continuous
wave doppler
NOTE: Increasing PRF will and switching to a lower frequency transducer will reduce, but not
fully eliminate
What does VTI x CSA equal? Correct Answer: Doppler stroke volume
What are the phases of the valsalva maneuver? Correct Answer: Strain and release
What occurs during the strain phase of valsalva maneuver? Correct Answer: Decreases venous
return, SV and CO
What occurs during the release phase of valsalva maneuver? Correct Answer: Increases venous
return, CO and BP
Taking in a breath ___________________ thoracic pressure Correct Answer: decreases
Does venous return increase or decrease with inspiration? Correct Answer: decrease
Mitral valve velocity during inspiration: Correct Answer: decreases
Tricuspid valve velocity during inspiration: Correct Answer: increases
What occurs after the R wave on ECG? Correct Answer: IVCT
What occurs after the T wave on ECG? Correct Answer: IVRT
