Accurately calculate Mitral Valve Area (MVA) using our online tool, based on the reliable Pressure Half-Time (PHT) method. Essential for diagnosing and monitoring mitral stenosis severity, this calculator provides instant results for medical professionals and students alike.
Formula:
The Mitral Valve Area (MVA) can be accurately estimated using the Pressure Half-Time (PHT) method, a standard echocardiographic measurement. The formula used is:
MVA = 220 / PHT
Where:
- MVA = Mitral Valve Area (in cm2)
- PHT = Pressure Half-Time (in milliseconds), obtained from the transmitral flow velocity Doppler envelope.
