PISA-Radios is the radial distance of the isovelocity shell from the orice (Figure - Regurgitant

Flow-PISA Radius)

PISA-Area

PISA-Radius = Radial distance of the isovelocity shell from the orice in cm

PISA-Alias Velocity

Reference: Schmailzl. K., Omerod, O., Editors. Ultrasound in Cardiology. Blackwell Science,

1994, p.125.

PISA-Alias Velocity is the peak velocity of the regurgitant jet on the Doppler display (Figure –

Regurgitant Flow-PISA Alias Velocity)

Regurgitant Volume Flow Rate (Rate)

Reference: Oh, J.K., Seward, J.B., Tajik, A.J. The Echo Manual. Boston:Little, Brown and

Company, 1994, p. 106

Rate is calculated in milliliters/sec.

Where: PISA-Area = Proximal isovelocity surface area in cm

PISA-Alias Vel. = Color ow velocity at radius r in cm/sec measured at the mitral orice on the

Color display.
