IVAD stands for Implantable Ventricular Assist Device. An IVAD helps a failing heart along by pumping blood. It is implanted in the abdomen, is pneumatically driven by an external console, and drains blood from the apex of the ventricle of the heart, and ejects it, in a pulsatile manner, into the ascending aorta. An IVAD can be used for the left, right, or both ventricles. It is a medium/long term device, usually used as a bridge to transplantation. The REMATCH trial suggests that it can be used independently, and possibly allow the heart to recover. However, this has not been tested against (current) maximal medical therapy.
The Thoratec IVAD is manufactured by the Thoratec Corporation
