What this trial studies

This study investigates the use of the CytoSorb device, a filter integrated into the heart-lung machine, to reduce the immune response during cardiac surgery for patients with heart failure. Vasoplegia, a condition characterized by low blood pressure after surgery, is a common complication that can lead to poor outcomes. The study aims to determine if minimizing the systemic inflammatory response syndrome (SIRS) can decrease the incidence of vasoplegia in these patients. It is a single-center, investigator-initiated study focusing on the efficacy and cost-effectiveness of this intervention.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with heart failure, specifically with a left ventricular ejection fraction of 35% or less, who are scheduled for cardiac surgery requiring cardiopulmonary bypass.

Not a fit: Patients who are incapacitated, require emergency surgery, or have severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of vasoplegia, improving recovery and outcomes for heart failure patients undergoing surgery.

How similar studies have performed: While the use of filters in cardiac surgery is a novel approach, similar studies have shown promise in reducing complications associated with systemic inflammatory responses.
