| Abstrakt: | 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. Study Design: Prospective clinical trial. Patients and 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. Conclusion: In post cardiac surgery patients, PAPO can be reasonably estimated by measuring the ratio E/Vp obtained with Doppler echocardiography. |
