Aortic Valve Area (AVA) Calculator
Welcome to the Aortic Valve Area (AVA) Calculator website. This calculator helps estimate the Aortic Valve Area (AVA) based on the Left Ventricular Outflow Tract (LVOT) and the velocities at two points (VT1 and VT2). Enter the required values to get your AVA result instantly.

Steps to Calculate Aortic Valve Area:
1. Enter the LVOT (Left Ventricular Outflow Tract) in millimeters.
2. Enter the velocities at two points, VT1 and VT2, in centimeters.
3. Use the formula AVA = (LVOT Area × VT1) ÷ VT2 to calculate the Aortic Valve Area (AVA).
