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

What is best formula to estimate mPAP on #echofirst?
📝 finds minimal end-diastolic PR pressure best correlation (R = 0.92) & diagnostic accuracy AUC 0.96 https://t.co/MCbDFf6aSN in almost 600 pts referred for RHC for PH dx, integrates both PR & TR signals
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
