Trial Summary

What is the purpose of this trial?

This investigation will be conducted as an interventional intention-to-treat clinical study in a population of end stage heart failure patients who meet specific inclusion and exclusion criteria. The multi-center study will be prospective, dual-armed, non-blinded (open-label) and randomized, comparing a treatment group receiving the Jarvik 2000 LVAS with Post-Auricular Connector to an active control group treated with the PMA approved Thoratec HeartMate® II LVAS for Destination Therapy.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that participants should be on Optimal Medical Management (OMM) or other specific treatments. It's best to discuss your current medications with the trial coordinators.

What data supports the idea that Jarvik 2000 VAS for Heart Failure is an effective treatment?

The available research shows that the Jarvik 2000 VAS is effective for heart failure treatment. In one study, 7 out of 10 patients survived to receive a heart transplant after using the device, and they underwent complete physical rehabilitation during support. Another study reported that 8 patients improved significantly, moving from severe heart failure to a much better condition, and 7 of them were able to receive a transplant. The device also helped improve heart function indicators, such as increasing the heart's ability to pump blood by 43% within 48 hours after surgery. Additionally, there were no early deaths during the initial period after surgery in one group of patients. These outcomes suggest that the Jarvik 2000 VAS can effectively support patients with severe heart failure, either as a bridge to transplantation or as a long-term solution. ^{1 2 3 4 5}

What safety data is available for the Jarvik 2000 VAS for heart failure?

The Jarvik 2000 VAS has been evaluated in several studies. In one study, 10 patients received the device, with no early perioperative deaths reported. The average support duration was 81.2 days, ranging from 13 to 214 days, and 7 out of 10 patients survived to transplantation. Another study reported that 7 out of 10 patients underwent transplantation, while 3 died during support. No device thrombosis was observed at explantation. These studies suggest that the Jarvik 2000 can provide effective cardiac support with a reasonable safety profile, although some risks remain. ^{1 2 3 4 6}

Is the Jarvik 2000 VAS a promising treatment for heart failure?

Yes, the Jarvik 2000 VAS is a promising treatment for heart failure. It helps patients with severe heart failure by supporting their heart function, allowing them to wait for a heart transplant or use it as a long-term solution. It can provide a strong blood flow, helping maintain important organ functions like the kidneys and liver. Many patients using it have successfully moved on to heart transplants and regained physical strength during its use. ^{1 3 4 6 7}

Eligibility Criteria

This trial is for adults with severe heart failure who are not eligible for a heart transplant. They must have been in late-stage heart failure for most of the past two months, have a specific body surface area, and be on optimal medical management or other support like IV inotropes. People can't join if they've had certain cardiac procedures, chronic immunosuppression, conditions limiting survival to under three years, intolerance to blood thinners, or sensitivity to bovine products.

Inclusion Criteria

Your body surface area is between 1.2 square meters and 2.5 square meters.

You are not eligible for a heart transplant.

You have had severe heart failure symptoms for most of the past two months.

Exclusion Criteria

You have had a heart transplant or a specific heart surgery to reduce the size of the left ventricle.

You are taking medication that weakens your immune system for a long time.

You have medical conditions, other than heart failure, that may make you unlikely to live for at least three years.

Findings from Research

The Jarvik 2000 Heart(TM) is a left ventricular assist device that successfully provided cardiac support with outputs up to 8 L/min in the first group of 10 patients, with no early perioperative deaths and an average support duration of 81.2 days.

Seven out of the 10 patients survived long enough to receive a heart transplant, indicating the device's potential as an effective bridge-to-transplantation option.

Anesthetic management for implantation of the Jarvik 2000 left ventricular assist system. Nussmeier, NA., Probert, CB., Hirsch, D., et al.[2021]

The Jarvik 2000 left ventricular assist system (LVAS) was implanted in 10 heart transplant candidates, showing significant improvements in heart function, including a 43% increase in cardiac index and a 52% decrease in pulmonary capillary wedge pressure within 48 hours post-surgery.

The device demonstrated safety with no thrombosis observed at explantation, and 8 out of 10 patients improved to NYHA class I after rehabilitation, indicating its potential to effectively support patients awaiting heart transplants.
