ASSESSMENT SEVERITY OF THE PATHOLOGY
ASE GUIDELINES
Volume and fraction
PHT (pressure half time)
Vena contracta
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.

COLOR DOPPLER OF THE AORTIC FLOW
21/02/2023
For studying the flow in Ascending Aorta by Color Doppler, the apical five-chamber position is the best choice. In this position, the flow is almost parallel to the ultrasonic beam. It is also possible to use the left parasternal approach, the long axis of the heart, And the Suprasternal View, the Long Axis of the aorta.
