ALL THE BASIC CALCULATIONS
LV EF% - Left Ventricle Ejection Fraction (Simpson Single Plane, Biplane), LV FS% - Left Ventricle Fractional Shortening, CO - Cardiac Output, SV - Stroke Volume, Cl - Cardiac Index, LV Mass - Left Ventricle Mass, PA pressure - Pulmonary artery pressure.
ASSESSMENT SEVERITY OF THE PATHOLOGY
Volume and fraction
PHT (pressure half time)
Virtual echocardiography can make all basic calculations which 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 preassure measurement: Systolic pressure, Diastolic pressure, Mid pressure.
Left Ventricular Diastolic Dysfunction: E, A, Septal e', Lateral e', TR, LA Volume.

PULMONARY ARTERY FLOW SPECTRAL (PW, CW) DOPPLER
The study is better to perform from a Parasternal Approach, the short axis of the heart, at the level of the Pulmonary Artery. The Sample Volume is placed in the Pulmonary Artery (1 cm distal of the Pulmonary Artery Valve).
