Clinical Trial 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).

Eligibility

Inclusion Criteria:

• At least 18 year old and able to provide informed consent;
• Consecutive patients scheduled for right heart catheterisation by a dedicated heart failure specialist at the Centre of Cardiovascular Diseases (University Hospital Brussels, Jette, Belgium).

Exclusion Criteria:

• Major anatomical variations of the portal veins (agenesis of left and right portal vein) and/or arterio-portal vein fistula;
• Patients with Child-Pugh B or C liver cirrhosis or liver transplant;
• Body Mass Index < 20 kg/m².

• Doppler Echocardiography
• Heart Failure

Intervention

Diagnostic Test:
• Comprehensive 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.
