About
The purpose of this study is to assess the feasibility of using the BiVACOR Total Artificial Heart (TAH) System to support adult patients with severe biventricular heart failure, or univentricular heart failure in which left ventricular assist device (LVAD) support is not recommended, who require mechanical circulatory support to sustain life. The BiVACOR TAH System is intended for use as a bridge to transplant (BTT). Feasibility will be assessed by evaluating safety and performance of the BiVACOR TAH System in study subjects.

Inclusion criteria
Patient has severe, irreversible biventricular heart failure and is eligible for biventricular mechanical circulatory support based on the International Society of Heart and Lung Transplantation (ISHLT) guidelines or has univentricular heart failure in which LVAD support is not recommended. ISHLT Guidelines for Biventricular Support:
Biventricular failure with at least two of the following hemodynamic and/or echocardiographic measurements.
Treatment-refractory recurrent and sustained ventricular tachycardia or ventricular fibrillation in the presence of untreatable arrhythmogenic pathologic substrate.
Heart failure due to restrictive or constrictive physiology (e.g., hypertrophic cardiomyopathy, cardiac amyloidosis/senile or other infiltrative heart disease).
Patient is categorized as INTERMACS Patient Profile Classification 2 or 3.
Patient is classified as NYHA Class IV.
Patient has a left ventricular ejection fraction (LVEF) ≤ 25%, with the exception of patients with restrictive or constrictive physiology.
Patient is inotrope dependent, OR has a cardiac index (CI) ≤ 2.2 L/min/m2 without inotropes if inotropes are contraindicated (e.g., restrictive or constrictive heart failure), and meets one of the following criteria:
Patient is eligible for cardiac transplantation as determined by the implanting center.
Patient has adequate room in the chest as determined by 3-D imaging or other standard clinical assessments.
Patient has read and understands the informed consent form (ICF) and has voluntarily provided informed consent.
Exclusion criteria
Patient has contraindications to anticoagulation or antiplatelet therapies.
Patient has coagulopathy defined by a platelet count < 50 k/µl.
Patient has insufficient space in the chest to accommodate the BiVACOR pump.
Patient has a body mass index (BMI) ≥ 35 kg/m2.
Patient is highly pre-sensitized prior to pump implantation.
Patient is unconscious and unresponsive.
Patient is on pre-implant extracorporeal membrane oxygenation (ECMO) for > 7 days.
Patient is on pre-implant temporary MCSD for more than 21 days [e.g., Intra-aortic balloon pump (IABP), Impella, CentriMag, etc.] unless ambulatory and free from adverse effects associated with the MCSD.
Patient is implanted with durable mechanical circulatory support (LVAD or RVAD).
Patient experienced cerebrovascular accident (CVA) within three months of eligibility evaluation.
Patient has severe end-organ dysfunction as evidenced by:
Patient has severe chronic obstructive pulmonary disease (COPD) or restrictive lung disease requiring home oxygen.
Patient has primary pulmonary hypertension ≥ 8 Wood units.
Patient has severe systemic light-chain amyloidosis.
Patient has been diagnosed with severe cardiac cachexia or irreversible frailty.
Patient has diabetes with advanced diabetic neuropathy with accompanying skin ulceration.
Patient has a blood-borne infection within seven days of eligibility evaluation. Positive blood cultures reflective of contaminants (e.g., Staphylococcus epidermidis) will not be considered an exclusion.
Patient is pregnant or planning pregnancy.
Patient has a co-morbidity or illness that would limit survival to less than two years.
Patient has a current drug and/or alcohol addiction or known substance abuse.
Patient has insufficient social support or a history of non-compliance with medical instructions as determined by the Investigator.
Patient is participating in another clinical trial that may impact or confound the results of the BiVACOR TAH EFS.
