ANSWERS RATED A+
✔✔Atrial Kick happens in _____ diastolic filling - ✔✔late, after P wave
✔✔Austin Flint murmur = - ✔✔AI
✔✔HRT sound associated with MVP - ✔✔systolic click
✔✔HRT sound associated with MS and TS - ✔✔opening snap
✔✔Early diastolic murmurs are due to what - ✔✔AI and/ or PI--- severity of regurg is
often inversely related to the duration of the murmur. With severe regurg Ao diastolic
pressure falls rapidly.
✔✔increased pain with changing positions are taking deep breaths, severe chest
(precordial) pain are signs of what - ✔✔pericarditis
✔✔T/F Females slightly more effected by myxomas compared to males - ✔✔True
✔✔Symp of MVP - ✔✔~~~Palpitations, sharp pain unrelated to exercise
~~~ Fatigue, dypnea
~~~ Dizzy spells
Can cause turbulent flow of blood in the aorta, increase in CO
✔✔In normal (laminar) BF, the velocity of the flow is highest where - ✔✔center stream
✔✔the system control that automatically calibrates for measurements - ✔✔Depth
control
✔✔Increasing gain will ___- specular echoes and ___ artifacts - ✔✔increase, increase
✔✔What is the purpose of TGC's - ✔✔1. suppress near field echoes
2. enhance far field echos
3. compensate for loss of ultrasound energy ( attenuation )
✔✔T/F inspiration can affect SAM - ✔✔False--- neither inspiration or expiration affects
SAM
✔✔T/F valsalva and amyl nitrite can bring out SAM - ✔✔true
✔✔The optimal Doppler angle is ______ degrees or ________degrees - ✔✔0 or 180
✔✔T/F the posterior leaflet of the MV is smaller than the anterior MV leaflet - ✔✔True
, ✔✔MV E-F slope can give indications for which diseases - ✔✔MS, and LV function
✔✔What is the mitral apparatus composed of - ✔✔1. MV leaflets, 2. Chordae tendinae
3. Paps 4. annulus
✔✔On MV M -Mode an increase in the A-C interval suggests what - ✔✔increased
LVEDp and possible poor LV function
✔✔How does lateral resolution affect measurements - ✔✔lateral resolution can make
lateral and medial walls appear wider. Axial resolution has no effect on measurements
✔✔Too high of gain can make orifice appear too _____ - ✔✔small
✔✔Following a commissuretomy of MV a valve orifice can be accurately evaluated
using what technique - ✔✔Doppler by using P1/2t
✔✔Flutter of teh IVS can be seen in _______ - ✔✔AI (not MR)
✔✔M-mode findings of MR - ✔✔1. dilated LV
2. LAE
3. Flutter of the posterior Ao Root
✔✔Myxomatous degeneration= - ✔✔thickening of the MV leaflets (often seen in MVP)
✔✔MAC may obsure - ✔✔1. anterior MV leaflet
2. Posterior MV leaflet
3. Endocardial echos caused by acoustic shawdowing
✔✔How are MR and TR easily differentiated on Doppler - ✔✔1. difference in timing of
the valve opening and closing
2. different location of the jets
3. different direction of the jets
4. different in forward flow velocity curves
✔✔The mormal brief posterior displacement of the IVS with the onset of diastole
(diastolic dip) may be exaggerated in what condition - ✔✔MS------ early diastolic LV
filling is restricted where as the RV fills rapidly. Therefore the septum bulges toward the
LV in early diastole
✔✔What is MV leaflet motion influenced by - ✔✔1. relative pressures in the LA and LV
2. velocity and lood volume of blood flow through the mitral orifice
3. LV diastolic compliance
4. systolic performance of the LV
