What is the Aortic Valve Area (AVA)?
The Aortic Valve Area (AVA) is a critical measurement used to assess the severity of aortic stenosis, a condition where the aortic valve narrows, restricting blood flow from the heart to the rest of the body. Calculating the AVA helps cardiologists evaluate heart function and plan appropriate treatment.

How to Calculate Aortic Valve Area?
The Aortic Valve Area can be calculated using the **Gorlin Formula** or Doppler echocardiography:
AVA = (Stroke Volume) / (Heart Rate x Gradient)
Alternatively, Doppler echocardiography uses the continuity equation:
AVA = (Cross-sectional Area of LVOT x Velocity of LVOT) / Velocity of Aortic Valve
You will need:
- The cross-sectional area of the left ventricular outflow tract (LVOT).
- Peak velocity or pressure gradients at the aortic valve.
- Stroke volume and heart rate (if using the Gorlin formula).
