Clinical Trial Summary

A prospective, multi-national, open-label clinical study which is conducted to asses the safety, feasibility and performance of the TRVD™ System in hospital-admitted patients with Acute Decompensated Heart Failure (ADHF) and evidence of reduced left ventricular ejection fraction.

The study will include patients who present with significant venous congestion, as evidenced by clinical, laboratory and imaging signs of fluid retention.

Study participation, for each enrolled subject, will last approximately 3 months post index procedure.

Patients will be evaluated from enrollment until hospital discharge, then at 30, 60, and 90 days post procedure.

3. Patient presents at least two of the following clinical signs of manifest volume overload: 3.1 Jugular venous distension 3.2 Dyspnea, rales, or evidence of pulmonary congestion or oedema on admission chest radiography 3.3 Abdominal discomfort compatible with internal organ congestion and/or hepatomegaly 3.4 Peripheral oedema

4. Ultrasonic evidence of IVC plethora, defined as IVC diameter >2.0 cm.

5. BNP levels >300 pg/dL or NT-proBNP >1500 pg/dL .

6. Evidence of cardiac etiology as per cardiac ultrasonography.

7. LVEF =/<40%.

8. CVP (Invasively measured) >/=14 mmHg

9. Male or non-pregnant / non-lactating female (NOTE: Females of child bearing potential must have a negative pregnancy test).

10. Patient understands the nature of the procedure and provides written informed consent prior to any study specific assessments.

Exclusion Criteria:

1. INR >3, use of a NOAC in the past 48 hours or contraindication to systemic anticoagulation with Heparin.

2. Evidence of hemodynamic instability, evidence of shock with organ hypoperfusion, or need for inotropic support.

3. Overt pulmonary oedema, or Respiratory insufficiency/hypoxia (peripheral haemoglobin saturation <90% with supplemental oxygen), need for non-invasive positive pressure ventilation or intubation.

4. Severe renal dysfunction (eGFR before decompensation <45 ml/min/1.73 m2 BSA or <25 on admission).

5. Known renal artery stenosis.

6. Known intrinsic kidney disease (e.g., established diagnosis of diabetic nephropathy with macroproteinuria, chronic glomerulonephritis).

7. Severe anaemia (haemoglobin <9 mg/dL).

8. Thrombocytopenia with a platelets count <100,000.

9. Acute coronary syndrome within 4 weeks prior to admission.

10. Active myocarditis or hypertrophic obstructive cardiomyopathy.

11. Complex congenital heart disease.

12. Severe valvular stenosis.

13. Severe morbid obesity (BMI >35).

14. Fluid retention that is not primarily of cardiac origin (e.g., advanced liver disease, severe hypo-albuminaemia, etc.)

15. Temperature > 38°C (oral or equivalent), or sepsis, or active systemic infection requiring IV anti-microbial treatment.

16. Large ascites per ultrasound/CT.

17. Cognitive impairment.

18. Planned PCI, or more than minor surgery in the next 3 months.

19. Moribund patient, or patient with malignancy or other comorbidities limiting life expectancy to less than one year.

20. Patient has a known allergy to Nickel.

21. Contraindication to recommended study medications or intravascular contrast material that cannot be adequately controlled with pre-medication.

22. Concurrent enrollment in another device or drug trial that has not completed the primary endpoint or clinically interferes with the current study endpoints.

Intervention

Device:
• TRVD Therapy
A catheter-mounted expandable flow pump is to be deployed in a transfemoral venous catheterization procedure. Once in place, renal venous pressure is reduced to a pre-selected physiologic target pressure and kept there for up to 24 hours. After termination of TRVD therapy, the device is removed.
