Echo Flashcards
1
Q
Fixed LVOT obstruction Doppler profile
A
obstruction last throughout systole => symmetric flow profile
2
Q
Dynamic LVOTO Doppler profile
A
obstruction increase in severity, highest at the end of systole => dagger shape flow profile
o Systolic anterior motion of the MV
o Normal early LV ejection with a late peak maximal gradient
3
Q
Pressure tracings w/ fixed LVOTO
A
o AoP: slow rate of increase throughout systole
o LVP: symmetric shape, peak in mid-systole
o Largest PG in early systole
4
Q
Pressure tracings w/ dynamic LVOTO
A
o AoP: rapid upstroke in early systole → flat
o LVP: maximal pressure at end of systole (highest PG)
