Key result
Ultrafiltration aids decongestion and cuts HF readmissions in selected trials, but overall evidence remains mixed.
Why the study?
Conflicting study results highlight that patient selection, fluid removal targets, and the optimal assessment of fluid status for ultrafiltration are not completely understood.
Does extracorporeal veno-venous ultrafiltration improve fluid removal, symptoms, and rehospitalization rates compared to standard intravenous diuretic therapy in patients with congestive heart failure and fluid overload?

Extracorporeal veno-venous ultrafiltration is a promising mechanical decongestion strategy for heart failure patients with diuretic resistance, though optimal patient selection and non-invasive fluid assessment targets require further validation.
continuous infusion. Ultrafiltration (UF) has been considered a promising alternative to stepped diuretic therapy and it consists in the mechanical, adjustable removal of iso-tonic plasma water across a semipermeable membrane with the application of hydrostatic pressure gradient generated by a pump. Fluid removal with ultrafiltration presents several advantages such as elimination of higher amount of sodium with less neurohormonal activation. However, the conflicting results from UF studies highlight that patient selection and fluid removal targets are not completely understood. The best way to assess fluid status and therefore establish the fluid removal target is also still a matter of debate. Herein, we provide an up-to-date systematic review about the role of ultrafiltration among patients with fluid overload and its gaps in daily practice.

Urbani et al. (2023) conducted a review in Congestive heart failure with fluid overload. Extracorporeal veno-venous ultrafiltration vs. Standard stepped intravenous diuretic therapy was evaluated. Extracorporeal veno-venous ultrafiltration shows beneficial effects on weight loss, symptom relief, and heart failure rehospitalization in selected trials, though overall evidence remains mixed.
