Management of Fluid Overload in Patients With Severe Aortic Stenosis (EASE-TAVR): A Randomized Controlled Trial.

Background: Fluid overload (FO) subjects patients with severe aortic stenosis (AS) to increased risk for heart failure and death after valve replacement and can be objectively quantified using bioimpedance spectroscopy (BIS).

Objectives: The authors hypothesized that in AS patients with concomitant FO, BIS-guided decongestion could improve prognosis and quality of life following transcatheter aortic valve replacement (TAVR).

Methods: This randomized, controlled trial enrolled 232 patients with severe AS scheduled for TAVR.

Quantitative fluid overload in severe aortic stenosis refines cardiac damage and associates with worse outcomes.

Aims: Cardiac decompensation in aortic stenosis (AS) involves extra-valvular cardiac damage and progressive fluid overload (FO). FO can be objectively quantified using bioimpedance spectroscopy. We aimed to assess the prognostic value of FO beyond established damage markers to guide risk stratification.
