Abstract

BACKGROUND
Doppler variable of mitral inflow have been used to assess left ventricular siastolic function indirectly. Pulmonary venous flow(PVF) variables could supplement mitral inflow in the estimation of left ventricular diastolic function. The purpose of this study are to assess the feasibility of PVF measurement by using transthoracic pulsed wave Doppler echocardiogram and to estimate the LV end-diastolic pressure with PVF parameters.
METHODS
Fifty six patients underwent transthoracic pulsed wave Doppler echocardiagraphy (HP Sonos 1500) within 2 hours before left heart catheterization for the measurement of left ventricular pressure.
RESULTS
1) Measurement of transthoracic PVF was feasible in 50 patients(89.3%). 2) The difference between the duration of pulmonary venous reversal flow and mitral A wave(D difference, delta D) was strongly correlated with left ventricular end diastolic pressure(r=0.73, p<0.01). PVF reversal duration exceeding that of mitral A wave predicted left ventricular end diastolic pressure > or =12mmHg(sensitivity 90.6%, specificity 50.0%).
CONCLUSION
PVF could be assessed with transthoracic Doppler ultrasound with good feasibility. PVF may be an important parameter in the evaluation of left ventricular diastolic function. PVF reveral duration exceeding that of mitral A wave would be a marker of elevated left ventricular end diastolic pressure(> or =12mmHg). Plumonary venous flow . Transmitral inflow .
