[Color M-mode Doppler for postoperative estimation of pulmonary capillary wedge pressure].
OBJECTIVE
The aim of this study was to evaluate the accuracy of the combined index E/Vp (peak E velocity combined with color M-mode color Doppler flow propagation) for estimating pulmonary capillary wedge pressure, in post cardiac surgery patients.


METHODS
Prospective clinical trial.


METHODS
In post cardiac surgery patients (D1), we have measured with transthoracic echocardiography peak early E transmitral pulsed Doppler velocities and color M-mode Doppler flow propagation velocity (Vp). The E/Vp ratio was compared with pulmonary capillary wedge pressure (PAPO) obtained simultaneously.


RESULTS
Thirty eight patients were studied. The coefficient of correlation between PAPO and E/Vp was r = 0.71 (p < 0.0001). The sensitivity and the specificity of E/Vp > 1.5 for prediction of PAPO > 15 mmHg were 79% and 79% respectively.


CONCLUSIONS
In post cardiac surgery patients, PAPO can be reasonably estimated by measuring the ratio E/Vp obtained with Doppler echocardiography.
