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

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)
