[Value of end diastolic pulmonary venous flow in the estimation of left ventricular diastolic pressure].

The aim of this study was to analyse the possible relationship between inversion of the end diastolic wave of pulmonary venous flow (Avp) recorded by transoesophageal echocardiography in the left superior pulmonary vein and left ventricular end-diastolic pressures (LVEDP) at cardiac catheterisation. In this series of patients, there was a poor correlation between the E/A ratio of transmitral blood flow and LVEDP. On the other hand, there was a better correlation between LVEDP and the difference of duration of the end diastolic Avp wave and the A wave of mitral flow.
