Summary

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).

Conditions

Interventions

TypeNameDescription
DIAGNOSTIC_TESTComprehensive transthoracic echocardiography, Doppler echography & Kino-cardiograph (Kino)As per inclusion criteria, all patients undergo right heart catheterisation to obtain a full profile of invasive hemodynamic measurements, including pulmonary arterial wedge pressure (PAWP), pulmonary artery pressure, right ventricular pressure, right atrial pressure (RAP), superior and/or inferior vena cava pressure, hepatic vein pressure with/without balloon occlusion. Immediately after the invasive hemodynamic exam, a comprehensive 2D, Color Doppler and Doppler echocardiography exam, including a Doppler study of the Vv. hepaticae, V. portae and V. renalis is performed. Based upon logistic feasibility, ballistocardiography and seismocardiography with the completely non-invasive Kino device (HeartKinetics, Waterloo, Belgium) is performed in a subpopulation of patients envisioned to be at least 50 patients.
