Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age >18
• Subject is admitted to the hospital with a primary diagnosis of acute decompensated heart failure (ADHF).
• Subjects receiving IV diuretic for ADHF and demonstrating fluid overload. This includes a minimum of 2 of the following:
• peripheral edema ≥ +2 (on a 0 to +3 scale, indicating indentation of skin with mild digital pressure that requires 10 s or more to resolve in any dependent area including extremities or sacral region);
• jugular venous distension ≥8 cm H2O
• pulmonary edema or pleural effusion on chest radiograph
• enlarged liver or ascites;
• paroxysmal nocturnal dyspnea or ≥ two-pillow orthopnea;
• dyspnea at rest with respiration rate ≥20 per minute
• Renal function parameters: 30<eGFR<80
• Biomarkers: BNP/pro-BNP
• BNP>400 pg/ml or NT-pro-BNP>1,600 pg/ml
• For patients with rate-controlled persistent or permanent AF: BNP>600 pg/ml or NT-pro-BNP>2,400 pg/ml
• Subject must be able to be enrolled into the trial ≤ 72 hours of their admission to the hospital
• Subject agrees to comply with all follow-up evaluations
• Subject has provided written informed consent; or if unable to perform informed consent, written informed consent on behalf of the subject has been provided by a legally-authorized representative

You may not qualify if…

• Subjects requiring inotropic therapy, mechanical ventilation, or mechanical circulatory support
• Subjects developing worsening renal function (creatinine >0.5 mg/dL above baseline) within the time frame from admission to enrollment.
• Subject has experienced a thromboembolic event (eg, pulmonary embolism (PE), deep vein thrombosis (DVT)) within the previous 6 months
• Subject has contraindications to systemic anticoagulation
• Subject with INR >1.8 or on novel anticoagulants (NOACs). Subjects who have taken NOACs may be enrolled if a minimum of 48 hours has passed since their last dose, with the exception of subjects on Dabigatran, who may not be enrolled.
• Subject has mechanical heart valve.
• Subject with systolic blood pressure < 90mmHg at time of enrollment
• Subject has evidence of active infection
• Subject has anatomical abnormalities and variations, or visualization of the insertion and deployment site does not enable safe venous access and device deployment as assessed by ultrasound
• Subject vein diameters proximal and distal to the internal jugular/subclavian vein bifurcation in area of device placement less than 13.5mm and/or greater than 205mm.
• Subject has experienced transient ischemic attack (TIA) events or cerebrovascular events (CVA) at previous 6 months
• Subject with Acute coronary syndrome (ACS).
• Subject with severe concomitant disease expected to prolong hospitalization or expected to cause death in ≤ 90 days
• Subject is pregnant. Pregnancy confirmed by positive urine or serum test, or lactating mothers
