The study of mitral flow and pulmonary venous flow by Doppler provides a non-invasive method of assessing diastolic function. But there are difficulties in differentiating normal pattern from «pseudo-normal »(Appleton Type II) (E/A Mitral > 1). Phonocardiography enables the recording of early (B3) and late (B4) diastolic gallops. The apexogramme enables calculation of the a/H and D/H ratios (amplitude of the " D " wave resulting from rapid early diastolic filling to the total amplitude of the apexogramme). These two techniques record pulsatile phenomena (" pulse waves ") arising from variations in intra-left ventricular pressure. They may complete the interpretation of Doppler recordings of velocities of blood flow (" flow waves "). To evaluate the value of each technique, the authors studied left ventricular diastolic function by Doppler phonocardiography and apexography in 60 subjects (38 patients of which 30 with ischaemic heart disease, and 22 healthy subjects). The results showed that increase in velocity and deceleration slope of the Doppler mitral E wave was associated with the presence of a B3 and correlated (r = 0.60 ; p = 0.0001) with the D/H ratio of the apexogramme. On the other hand, the absence of correlation between the mitral A wave velocity and a B4 associated with an increased a/H ratio enables the differentiation of normal Doppler mitral flow (absence of B4, Doppler a/H ratio < 12 %) from pseudo-normal appearances (B4, a/H ratio > 12%). Therefore, the evaluation of diastolic function by Doppler mitral and pulmonary venous flow analysis may be usefully completed by phonocardiography and apexography.
