Aortic Valve Area Calculator

Aortic Valve Area Calculator calculator can be used to estimate the aortic valve area using echocardiographic measurements.

Input Parameters

Calculation Results

Calculation Formula

Aortic Valve Area = Valve Area by Continuity Equation / Ratio of Vj/Vm

Where:
Valve Area by Continuity Equation: Estimated using the continuity equation (cm²)
Ratio of Vj/Vm: Ratio of the aortic jet velocity to the peak mitral inflow velocity

Result

-- cm²

How to Use the Calculator

  1. Enter the Aortic Valve Area by Continuity Equation in cm².
  2. Enter the Ratio of the Aortic Jet Velocity to the Peak Mitral Inflow Velocity (Vj/Vm).
  3. Click the "Calculate" button to estimate the Aortic Valve Area.
  4. The result will be displayed in cm².

Working Principle

The Aortic Valve Area Calculator uses the modified continuity equation to estimate the aortic valve area. The continuity equation is based on the principle of conservation of mass, where the flow across the aortic valve is equal to the flow across the mitral valve. The formula used is:

Aortic Valve Area = Valve Area by Continuity Equation / Ratio of Vj/Vm

This method is useful in echocardiographic assessments of aortic stenosis and helps in determining the severity of the condition.
