About this trial
This is an interventional device feasibility trial for Heart Failure focused on measuring Heart Failure
Eligibility Criteria
Inclusion Criteria:
- 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
Exclusion Criteria:
- 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
