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).

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.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
