Virtual echocardiography can make all basic calculations that are recommended by the American Society of echocardiography (ASE) for assessment of the severity of the disease:

MV Stenosis: MVA Tracing, PISA. PHT, MVA by Continuity equation, PG max.

MV Regurgitation: Regurgitation Area, Reg Area / LA area, PISA, Regurgitation volume and fraction (Continuity equation), Vena Contracta.

Ao Stenosis: Pic Velocity, PG mid, AVA by Continuity equation.

Ao Regurgitation: PHT, D reg / D Lvot, Area reg / CSA Lvot, PISA, Vena Contracta, Regurgitation volume and fraction (Continuity equation).

TV stenosis: MG mid, TVA by Continuity equation, PHT. VTI.

TV Regurgitation: Regurgitation area, PISA.

PA stenosis: Flow Velocity, PG systol.

PA Regurgitation: Regurgitation jet size.

PA pressure measurement: Systolic pressure, Diastolic pressure, Mid pressure.

Left Ventricular Diastolic Dysfunction: E, A, Septal e', Lateral e', TR, LA Volume.

Vena Contracta - this is the width of the flow at the site of its formation, the so-called neck of the regurgitation, the narrowest point of the flow, at the ends of the leaflets of the closed mitral valve.
