,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

, 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
