Promising results are reported for a new ventricular assist device

Reported by Susan Aldridge, PhD, medical journalist

New device offers superior approach for assisting patients with heart failure.
The ventricular assist device (VAD) is an artificial pump which is implanted to support a failing heart. It can act as a 'bridge' for a patient with heart failure awaiting a transplant. But current VADs all come into contact with the circulation and, as such, pose a risk of blood clotting and strokes. A new device, the MYO-VAD, promises to overcome some of these complications and is easier and cheaper to use.

Researchers at Wright State University School of Medicine, Ohio, report promising results on a trial of the MYO-VAD in animals. When fitted with the devices, the key biomarkers of heart failure improved, suggesting the device can support a failing heart. The MYO-VAD is a flexible polymer cup which fits around the heart, compressing and expanding its lower chambers and so augmenting its pumping action. It can be fitted within about three minutes and its simplicity and low risk of complications promises to improve the treatment of heart failure, while reducing costs.
