HR (Heart Rate)

CONT (Continuity Equation)

When there is a constant ow in a ow channel with a Stenosis, the ow volume at the

Stenosis portion equals that at nonstenotic portions.

This equation is valid not only in a constant ow, but also in a pulsality ow channel.

where, SV1 : stroke volume in the nonstenotic area, SV2: stroke volume in the stenotic area

where, AVA (1) : Aortic Valve Area by Velocity, AVA (2) : Aortic Valve Area by VTI, LVOTarea : π

* DiaLVOT2 / 4, VTI1 : Left Ventricle output track VTI, VTI2 : Aortic valve VTI, V1 : Left Ventricle

output track velocity, V2: Aortic valve velocity
