About this study
Official title: Prevention of Vasoplegia With the Use of CytoSorb.
Vasoplegia is a common complication after heart surgery for heart failure. With vasoplegia, the blood vessels can no longer squeeze properly, causing low blood pressure that is sometimes difficult to treat with medication. One of the causes of this complication is likely to be the use of the heart-lung machine, a device that takes over the function of the heart and lungs during surgery. The blood then comes into contact with a foreign environment and this can cause a reaction of the immune system. Patients with heart failure are extra sensitive to this reaction.
CytoSorb device is a filter that can be built into the heart-lung machine and can reduce the response of the immune system. Therefore, this study aims to investigate whether the use of this filter during heart surgery in patients with heart failure results in a less frequent occurrence of vasoplegia after surgery.
Read the detailed description
The incidence and prevalence of chronic heart failure is increasing. Despite the expansion of therapeutic options, overall survival and quality-of-life remain poor. When optimal medical therapy and cardiological interventions have failed to improve a patient's condition, surgical intervention may be a valid option in order to improve cardiac function. Different surgical treatments have improved clinical outcome. Unfortunately, heart failure surgery is associated with an increased risk of vasoplegia. This syndrome is characterized by hypotension and the continuous need of vasopressors, despite a normal or high cardiac index. The incidence of vasoplegia ranges from 11-31% in patients undergoing heart failure surgery. The prognosis of vasoplegia is poor. Prolonged hypotension and the accompanying hypoperfusion lead to end-organ dysfunction and is associated with an increased morbidity and mortality. The investigators hypothesise that the balance of the vascular system of patients with heart failure is fragile and therefore could easily be disturbed by a systemic inflammatory response syndrome (SIRS) caused by the cardiopulmonary bypass (CPB) and surgical trauma, making these patients more prone to develop vasoplegia. Minimising this SIRS reaction could be a strategy to prevent vasoplegia. Therefore, the objective of this single-center, investigator-initiated study is to analyse the efficacy and cost-effectiveness of using CytoSorb in preventing vasoplegia in patients with heart failure undergoing cardiac surgery on CPB.
CytoSorb treatment will be conducted intraoperatively and the device will be applied in a parallel circuit in the CPB. The total study intervention protocol takes 5 days and starts on the day of the surgery (day 0) and ends at day 4 postoperatively. Patient clinical data will be collected until day 30.
The vascular reactivity in response to a vasoconstrictor will be assessed in all patients at 3 different time points (after induction, after CPB, on day 1 postoperatively). During the vasoconstriction test, a bolus of 2 μg/kg phenylephrine is administered intravenously, after which the effect on the systemic vascular resistance is registered. At the same time points and in addition, before induction (baseline) and on day 4 the sublingual microcirculation will be monitored and blood samples will be collected.

Questions about this trial
What is this clinical trial studying?
A study testing CytoSorb device in people with Heart Failure and Vasoplegia, run by Leiden University Medical Center at 1 site in Netherlands.
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 4 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 13 Dec 2023. 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 Netherlands. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Olga Papazisi, MD (+31715264022, o.papazisi@lumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Delta systemic vascular resistance index (SVRi) after CPB. (time frame: during surgery (2-10 hours)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04812717, which also lists 1 linked publication.
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 13 Dec 2023; AzTrials last refreshed its copy on 8 Nov 2026.
