Overview
This study evaluates the accuracy of a comprehensive venous Doppler echography including the portal vein pulsatility index (PVPI) to quantify invasively measured right-sided venous pressures. A substudy will correlate invasive and non-invasive hemodynamic measurements to ballistocardiography and seismocardiography with the Kino-cardiograph (Kino) device (HeartKinetics, Waterloo, Belgium).
