What aortic cusp is posterior in PLAX view? - ANS NCC
From the left parasternal window which of the following are you most likely to get accurate
velocity measurments? - ANS Pulmonary artery

,What are the tricuspid leaflets seen in the inflow view? - ANS anterior and posterior
Where is the LAA located on TTE? - ANS 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: - ANS Sinuses of Valsalva
What is the most anomalous artery? - ANS Right coronary
During which phase do the coronaries fill? - ANS early diastole
True/False --- The coronary arteries can fill during systole - ANS False
When is TAPSE measured? - ANS Between end diastole and peak systole
This is the transition between the sinuses of Valsalva and the tubular portion of the ascending
aorta - ANS STJ (sinotubular junction)
What can sometimes be seen below the RPA in a SSN view? - ANS Left atrium
The best images of the ascending aorta are often obtained from which transducer window? -
ANS suprasternal
Name the vessels coming off the arch and most proximal or distal. - ANS Innominate
(proximal), left carotid and left subclavian (distal)

,What cardiac pathology is associated with bicuspid aortic valves? - ANS Coarctation of the
aorta
Which window do you use to look for the secondary finding in bicuspid valves? -
ANS Suprasternal arch; suprasternal notch
Where do most aortic coarctations occur? - ANS aortic isthmus
How can we specifically identify the location of an aortic isthmus? - ANS After the take-off of
the left subclavian artery
Where are the pulmonary veins located? Where are they best visualized? - ANS Feed into the
LA and are best visualized in 4 chamber
What pulmonary veins are viewed in apical 4 chamber? - ANS Lower pulmonary veins
What pulmonary veins are viewed in apical 5 chamber? - ANS Upper pulmonary veins
From the apical 4 chamber view how do you rotate the transducer to obtain the apical LAX? -
ANS clockwise 120 degrees
Where is the coronary sinus located? - ANS posterior AV groove
Which view do you use to evaluate the coronary sinus? - ANS PLAX

, To visualize the coronary sinus in the apical 4 chamber view you should tilt the transducer: -
ANS posterior
Which valve sits at the opening of the coronary sinus? - ANS Thebesian
What valve sits at the opening of the IVC? - ANS Eustachian
Where is the Chiari network located? - ANS Right atrium
What portion of the pulmonary venous PW Doppler represents atrial systole? - ANS A wave
At what temperature is it unsafe to use a TEE probe? - ANS 40-45 degrees celcius (Above 41
degrees celcius)
Which electrical pathway has the fastest intrinsic rate? - ANS SA node
What is the absolute refractory state? - ANS period when a muscle cell is not excitable;
occurs from phase 1 into phase 3
What is a normal duration for the QRS complex? - ANS 0.10 sec or 100 msec
This is known as the rubber band theory - ANS Frank Starling Law
What occurs during preload? - ANS Filling
What is occuring during afterload? - ANS Resistance to eject blood out
