confusing LVOT Doppler signal w mitral regurgitation due to SAM in hypertrophic CM?

double check if it’s really the LVOT signal by estimating LVOT gradient with SBP/peak MR jet
& see if this matches measured LVOT (4v2) gradient

1.Peak MR signal(velocity) gives LVP-to–LAP gradient (4V2)

2.LVSP estimated by LV-LA gradient + LAP (~10-20mm Hg)

3.LVOT gradient estimated by LVSP – systolic BP #echofirst @echo_batman

At 24.5 mm Hg cutoff, mPAPDPmin 89% sensitivity, 94% specificity

At 20 mm Hg, mPAPDPmin sensitivity⬆️99% w/ net reclassification driven by more accurate downgrading of pts w/o PH
