Further study details as provided by NovaShunt AG:

Primary Outcome Measures:
  • To evaluate safety of the Automated Fluid Shunt device during a 28-week follow-up and to evaluate its efficacy by measuring change in NT-proBNP from baseline to 16 weeks, in patients with chronic congestive heart failure, ascites and diuretic resistance. [ Time Frame: 16 and 28 weeks ]

Secondary Outcome Measures:
  • To determine the effect of AFS-treatment on functional capacity (NYHA class and 6-min. walking distance) compared from baseline to 16 and 28 weeks [ Time Frame: 16 and 28 weeks ]
  • To determine change in LV volumes and LVEF (echocardiography) compared from baseline to 16 and 28 weeks [ Time Frame: 16 and 28 weeks ]
  • To determine change in ascites, hydrothorax and leg edema (based on CT evaluation) compared from baseline to 16 and 28 weeks [ Time Frame: 16 and 28 weeks ]
  • To determine change in renal function (GFR) compared from baseline to 16 and 28 weeks [ Time Frame: 16 and 28 weeks ]
  • To determine change in quality of life based on Minnesota Living with Heart Failure Questionnaire (MLHFQ) compared from baseline to 4, 12 and 28 weeks [ Time Frame: baseline to 4, 12 and 28 week ]
