Medical device to assist or replace a heart
Ventricular assist device
A ventricular assist device (VAD), also known as a ventricular assist system (VAS), is an electromechanical medical device that, by use of an artificial pump inserted into one or both of the ventricles, assists the heart in delivering blood to the rest of the body. Ventricular assist devices are designed to support cardiac pump function in patients suffering from acute or chronic heart failure or other weakening of the heart, with the devices partially or completely replacing the organ's functions. The type of VAD implanted depends on whether the device will support the heart's left ventricle (LVAD), right ventricle (RVAD), or both ventricles (BiVAD), as well as whether it will be used in the short-term, such as recovery from myocardial infarction, or the long-term, such as bridge to transplantation or destination therapy.
