In 1988, Appleton et al.(1) investigated the relation between transmitral Doppler flow
dynamics and invasively determined measurements of pressure and flow in a variety of …

Impaired relaxation is frequently masked by elevated filling pressures, resulting in a
pseudonormal flow pattern (E/A> 1.0). Because the E/A wave ratio increases as filling …

802 produces rapid early diastolic flow that quickly propagates to the apex. Because the
diastolic intraventricular pressure gradient pulls blood to the apex, it can be considered a …

The objective of this study was to evaluate the effect of alterations in preload induced by
lower body negative pressure on Doppler transmitral filling patterns. Echocardiograms and …

Although a number of factors, including age and ventricular loading, are known to influence
the pattern of left ventricular (LV) filling as depicted by Doppler echocardiographic …

Transmitral flow velocity pattern obtained by the pulsed Doppler technique reflects left
ventricular (LV) diastolic function, but an increase in left atrial pressure pseudonormalizes …

Objectives. This study was designed to evaluate the relation between the velocity of flow
propagation and left ventricular relaxation by using color M-mode Doppler …

Objectives. This study was designed to assess whether the transmitral flow velocity pattern
provides an estimation of left atrial pressure irrespective of the presence of left ventricular …

Diastolic Doppler flow signals (≥ 0.2 m/s) in the left ventricular outflow tract have not been
well characterized, and their origin and significance remain controversial. Fiftynine patients …

In patients with heart disease, changes in left ventricular filling pressures produce alterations
in the Doppler transmitral flow velocity and isovolumetric relaxation time. This investigation …
