About this study

Official title: Assessment of Response to Vascular Filling by Uncalibrated Pulse Wave Contour Analysis in Beating Heart Cardiac Surgery

The goal of this observational study is to Compare the performance of uncalibrated pulse wave contour analysis compared with transesophageal echocardiography (TEE) to assess response to a vascular filling test during beating-heart coronary artery bypass surgery, in people over age of 18; hospitalized for scheduled beating heart bypass surgery The aim question is to evaluate the ability of a less invasive cardiac output monitor (uncalibrated pulse wave contour analysis) compared with a reference cardiac output measurement (transesophageal echocardiography) to enable optimization of vascular filling by good assessment of the response to vascular filling in a high-risk perioperative patient population.

As part of hemodynamic monitoring, every patient undergoing beating-heart coronary bypass surgery is fitted with a radial arterial catheter immediately after induction of anesthesia, enabling continuous measurement of blood pressure. Hemodynamic optimization in these patients also involves fitting a transesophageal ultrasound probe to optimize cardiac output using the various therapies available (vascular filling, vasopressors, inotropes).

A specific sensor (FloTrac°, Hemosphere, Edwards°) will be connected to the arterial pressure line to obtain a systolic ejection volume value by analyzing the contour of the uncalibrated pulse wave.

The hemodynamic management of the patient, and the decision to perform a vascular filling test, will be left to the discretion of the practitioner in charge of the patient in the operating room.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Response to vascular filling

    an increase of more than 10% (compared with basal value) in the sub-aortic VTI value measured in TEE after filling (gold standard).

    Measured: From enrollment to completion of chirurgy (24 hours)

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Surgery, run by Centre Hospitalier Universitaire de la Réunion at 1 site in Reunion.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Reunion. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Response to vascular filling (time frame: From enrollment to completion of chirurgy (24 hours)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2026.
