FAQs

How do you calculate the area of a mitral valve?

The area of the mitral valve is usually measured using echocardiography. There are several methods to calculate mitral valve area, including:

1. Planimetry: Directly tracing the mitral valve orifice in a still image to calculate the area.

2. Pressure Half-Time Method: Measuring the time it takes for the pressure across the mitral valve to decrease by half after aortic valve closure.

3. Doppler Echocardiography: Using the velocity of blood flow across the mitral valve to estimate the valve area.
