💥Question 10 #ASEchoJC❓
What are the #EchoFirst criteria to determine suitability for PBMV (aka PMBV or PMBC)? After PBMV, how do we define success, and do we identify severe MR?

🔺PBMV if symptomatic severe MS, pliable valve, <2+ MR & no LAA thrombus
🔺Consider in asymptomatic severe MS & PASP>50 mmHg
🔺Wilkins score <=8
🔺Importance of careful #iEcho guidance, watch for severe acute MR

#ASEchoJC Wilkins score for assessing suitability for PBMV. Can consider >8 in very selected cases based on specific morphologic features.
💥Question 3 #ASEchoJC❓
What are the pitfalls and potential sources of error in assessing rheumatic MS severity by direct planimetry or CWD spectral display of mitral inflow (mean gradient, VTI, PHT)?

🔺MG influenced by HR (ok only between 60-80 bpm), cardiac output, mixed valve disease
🔺Always report rhythm and heart rate
🔺PHT >150 ~ MVA <1.5 cm2 in RHD, assuming normal LV & LA compliance (unreliable in calcific MS)
🔺Trace mid-diastolic slope
🔺Avoid after PMBV

🔺2D planimetry should transect leaflet tips perpendicular to LV axis
🔺Overestimation is common; look at the shape of LV in SAX (⭕️vs🥚)
🔺Caution with gain settings
🔺Consider biplane imaging & 3D #EchoFirst

Can a single cycle length method can be used to calculate aortic EOA in aortic stenosis w nonsinus rhythms?

LVOT TVI by PWD & AV VTI CWD measured over 5-10 consecutive beats in AF group & over 3-5 consecutive sinus beats in FE,EOA & DVI calculated as guidelines standard
In all patients, LVOT diameter was measured in midsystole, within 2-4 mm apical to annulus

RR intervals matched
AF pts, a single VTIAV was measured & then matched to a VTILVOT of similar cycle length defined as R-R intervals w/in 10% of each other,EOA & DVI calculated for short & long R-R cycles
