BSA — m²
Prosthetic aortic valve: EOA, DVI and indexed EOA
Continuity-equation EOA (stroke volume / prosthetic AV VTI), Doppler velocity index (LVOT VTI / prosthetic AV VTI) and measured indexed EOA.

Quick reference:↑ Prosthetic aortic valves
cm
PW Doppler just proximal to the valve (for TAVI, immediately proximal to the stent inlet)
cm
Needed for EOA; not needed for DVI. Largest diameter perpendicular to the LVOT; TAVI: outer-to-outer stent diameter at the lower end of the stent
mL
Optional: volumetric stroke volume (3D or contrast-enhanced LV volumes) instead of LVOT diameter × VTI
BSA (from context)—m²
Enter LVOT VTI, Prosthetic AV VTI (CW) to calculate.
