A cardiac assist device, also known as a ventricular aid device, is a mechanical appliance for helping cardiac circulation that is used to either partially or fully replace a failing ventricle. This sort of appliance stimulates the heart to pump at a higher rate than it would if it had no stimulus, such as when the heart is at rest in a resting state. They can be used in various different ways, but their main function is to provide stimulation and a source of the electrical energy that allows a ventricle to function in a certain way. They are especially valuable for people suffering from various heart diseases and can help prevent or at least reduce the damage caused by them.
Certain cardiac assist devices actually stimulate the heart to pump even more blood, increasing its ability to pump oxygenated blood to all parts of the body and removing lactic acid from within the muscle tissue. They work in a way that the heart does not have to use as much energy, so the person using them can actually use less overall energy. The device essentially "feeds" the heart, so to speak, giving it more stimulation and allowing it to perform at a higher level. By increasing the efficiency with which the heart pumps, cardiac assist devices can help prevent heart failure and other serious medical conditions.
Some of these devices actually come along with a small electronic device that is implanted directly under the skin. This allows them to be taken out of the body following surgery and a new normal pacemaker may then be surgically attached to the transplanted pacemaker. In many cases, this can help provide the necessary electrical energy required by the recipient of the cardiac assist devices to help restore their heart function.
