DRAIN-HF: Diuretics Alone vs. Aortix Endovascular Device for Acute Heart Failure
Aortix is a circulatory support device for chronic heart failure patients on medical management who have been hospitalized for acute decompensated heart failure (ADHF) and have persistent congestion despite usual medical therapy. Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management.
The study is a prospective, multi-center, randomized, nonblinded study to evaluate the safety and effectiveness of the Aortix System versus standard of care medical therapy in patients hospitalized with acute decompensated heart failure (ADHF) and persistent congestion despite usual medical management.Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management. Randomization will be stratified by ejection fraction..
An additional registry arm will enroll patients who are considered candidates for advanced therapies in the near-term, but need improvement in their renal function to be able to receive additional medical therapies. All eligible enrolled registry subjects will receive Aortix system support.
Planned study population is male or female patients 21 years of age or greater, with acute decompensated heart failure and diuretic resistance who remain congested despite standard of care medical therapy.
This study will enroll up to 295 subjects with heart failure at 45 clinical sites in the United States and up to 5 OUS sites. The randomized study includes up to 215 subjects and the Advanced HF registry includes up to 80 subjects.

2. GI bleeding within 6 months requiring hospitalization and/or transfusion,

4. Procedure with arterial ilio-femoral access > 6 FR within 30 days,
