Mitral Valve Area Calculator

How to use the Mitral Valve Area Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

LVOT_area = (0.5 × LVOT_diameter)^2 × pi

MVA_continuity = LVOT_area × (LVOT_VTI / MV_VTI)

MVA_PHT = 220/PHT

MVA_DT = 759/DT

Frequently asked questions

What is a Mitral Valve Area Calculator?

A Mitral Valve Area Calculator is a tool designed to estimate the effective area of the mitral valve using Doppler echocardiography measurements. This calculator helps in assessing mitral valve stenosis severity, allowing healthcare professionals to make informed decisions regarding treatment options.

How is the Mitral Valve Area calculated?

The Mitral Valve Area is typically calculated using the formula:

• A = (Flow velocity through the mitral valve) / (Velocity time integral)
• More specific methods incorporate the continuity equation, taking into account the left ventricular outflow tract area and velocity.

Why is measuring the Mitral Valve Area important?

Measuring the Mitral Valve Area is crucial for diagnosing and guiding the treatment of mitral valve disorders, particularly mitral stenosis. An accurate assessment helps in determining the severity of the condition, predicting outcomes, and planning interventions such as balloon valvuloplasty or surgical repair.
