European Study of the BrioVAD Heart Pump for Advanced Heart Failure

European Investigation of the BrioVAD Left Ventricular Assist System for the Treatment of Refractory Left Ventricular Heart Failure

This clinical investigation evaluates the safety and clinical performance of the BrioVAD Left Ventricular Assist System in patients with advanced, refractory left ventricular heart failure who require mechanical circulatory support.

This clinical investigation is conducted to assess the clinical performance and safety of the BrioVAD Left Ventricular Assist System (BrioVAD System) when used for mechanical circulatory support in patients with advanced, refractory left ventricular heart failure.

The BrioVAD System is a fully magnetically levitated, centrifugal-flow left ventricular assist device (LVAD) intended to provide short-term and long-term mechanical circulatory support (MCS) in patients with advanced, refractory heart failure who remain symptomatic despite optimal medical and device therapy. The BrioVAD System is intended for use both inside and outside the hospital environment.

This investigation is designed as a prospective, multi-centre, single-arm, non-inferiority clinical investigation. The performance of the BrioVAD System will be evaluated against a pre-defined Objective Performance Goal (OPG) based on contemporary LVAD clinical outcomes.

The primary objective is to demonstrate that the BrioVAD System provides non-inferior clinical benefit, as measured by survival free from device replacement/removal due to device malfunction at 6 months post-implant, compared with the OPG.

EXCLUSION CRITERIA:

1. Patient's heart failure etiology is related to restrictive or constrictive physiology (e.g., nondilated hypertrophic cardiomyopathy, cardiac amyloidosis/senile or other infiltrative disease), complex congenital heart disease (e.g., transposition of the great vessels), uncorrected thyroid disease, and/or pericardial disease.

6. Patient has known hypo- or hypercoagulable state [e.g., disseminated intravascular coagulation (DIC)], or has a positive heparin-induced thrombocytopenia (HIT) assay and positive serotonin release assay or requires use of a non-heparin alternative anticoagulation strategy for cardiopulmonary bypass in the judgement of the Investigator.

7. Patient is on durable MCS (e.g., LVAD or RVAD).

8. Planned need for durable or temporary RVAD support concomitant with LVAD implant.

9. Patient is on any form of pre-implant temporary MCS other than isolated LVAD support with an IABP.

10. Patient is on any form of pre-implant temporary MCS with a serum lactate dehydrogenase greater than 2.5 times the upper limits of normal or with plasma free hemoglobin > 40 g/dL.

11. Patient has a history of organ transplantation.

12. Patient has a mechanical aortic valve that may not be converted to a bioprosthetic valve at the time of VAD implant.

13. Patient has a platelet count < 50 k/µl.

14. Patient has a history of confirmed untreated abdominal aortic aneurysm (AAA) > 5 cm in diameter.

15. Patient has moderate or severe aortic insufficiency that will not be corrected during the VAD implant procedure.

16. Patient has an uncontrolled systemic infection.

17. Patient has a positive COVID 19 test within 21 days of study enrollment and at least one high risk feature including need for supplemental oxygen or ferritin >1000 ug/L.

18. Patient has severe end-organ dysfunction as evidenced by one or more of the following criteria:

    1. Total bilirubin > 3.0 mg/dL or cirrhosis confirmed by liver imaging or hemodynamic assessment with or without biopsy confirmation.
    2. International normalized ratio (INR) ≥ 2.0 or PTT > 2.5 times control that is not related to anticoagulation therapy.
    3. Glomerular filtration rate (GFR) < 30 mL/ min/1.73 m2 or need for renal replacement therapy.
    4. Severe pulmonary arterial hypertension with a pulmonary vascular resistance (PVR) ≥ 8 Wood units that is not acutely reversible with pharmacologic intervention.
    5. Severe chronic obstructive pulmonary disease (COPD) or restrictive lung disease requiring home oxygen or an FEV1/FVC < 0.7 and FEV1 < 40% predicted.
    6. Mechanical ventilation for more than three days present at the time of study enrollment.
    7. Documented history of pulmonary embolism or pulmonary infarct within 60 days of study enrollment.
    8. History of stroke within 90 days of study enrollment or history of stroke with a mRS ≥ 3 at the time of study enrollment.
