Aortic Valve Area Calculator
The Aortic Valve Area Calculator evaluates the functional size of the aortic valve, essential for diagnosing and managing aortic stenosis. Using the continuity equation, it calculates the valve area based on the Left Ventricular Outflow Tract (LVOT) diameter and flow velocities (VT1 and VT2). This tool provides immediate insights for clinicians and patients, ensuring accurate and efficient assessment.
Formula
Aortic Valve Area (AVA) = (LVOT Area × VT1) ÷ VT2
How to Use
Enter the LVOT diameter (in mm), VT1 velocity (in cm), and VT2 velocity (in cm) into their respective fields. The calculator will automatically compute the Aortic Valve Area using the continuity equation. The result, including a step-by-step solution and visual chart, will appear below.

FAQs
1. What is an Aortic Valve Area Calculator?
The Aortic Valve Area Calculator measures the functional area of the aortic valve using clinical parameters like LVOT and flow velocities (VT1, VT2). It is essential for assessing valve performance.
2. How accurate is the AVA calculation?
The accuracy depends on the precision of the input parameters. Ensure correct measurement of LVOT diameter and flow velocities.
