Abstract
Purpose of Review
Reduced responsiveness to diuretics is ubiquitous and multifactorial in heart failure and portends poor outcomes. Due to the limitations of current diuretic approaches, there is an enormous unmet clinical need for more effective fluid removal methods in heart failure patients.
Recent Findings
Novel volume management approaches include veno-venous ultrafiltration, peritoneal-based sodium and water removal methods, controlled diuresis, transvenous renal venous decongestion, catheter-deployed pumps in the descending aorta to increase renal perfusion, device-driven increase of lymphatic flow into the venous system, and catheter-based splanchnic nerve modulation.
Summary
Overall novel fluid management therapies are at an early stage of development, with some still in pre-clinical trials and others having been studied in first-in-man trials with a small number of subjects. Further investigation of novel fluid management methods should focus on assessment of safety, ease of use, candidates’ selection, reproducibility of effects across heart failure patient populations, and costs.
