Contribution to the theoretical study of the Doppler half-time method for the measurement of the cross-sectional area of the mitral valve.
The acceleration term is included in the expression of the Bernoulli equation and an application of this formalism to the study of the Doppler measured mitral flow velocity is discussed. Based on calculation of the time-to-time variation of the parameters involved, a possible theoretical explanation of the pressure half-time method for the measurement of the cross-sectional area of the mitral valve is given.
