TAH(Total artificial heart)

The TAH is an implanted device that replaces both the right and left ventricles, as well as the four heart valves, and takes up the area of a failing human heart that has been removed. In patients with end-stage heart failure affecting both sides of the heart, the TAH is employed (biventricular failure).

Insertion of LVAD (Left Ventricular Assist Device)
An LVAD requires open cardiac surgery to be implanted. You will be unconscious the entire time because the procedure is performed under general anaesthetic. The operation takes 4-6 hours to complete.

To access your heart and install the LVAD, the surgeon will make an incision below your chest and open your chest bone (sternum). Doctors may choose to create an incision on the left side of your chest depending on your condition (Thoracotomy).

A heart-lung bypass machine may be utilised during the procedure to distribute oxygen-rich blood throughout your body. During the procedure, a breathing machine (ventilator) will take over your breathing. After the LVAD is installed, the incision will be closed.

ICD implantation entails the following steps:

A pulse generator is implanted in a pouch beneath the skin of the chest or belly, commonly just below the collarbone. The generator is approximately the same size as a pocket watch.
Wires or leads extend from the pulse generator to spots on or inside the heart, and can be implanted through blood arteries, preventing open-chest surgery.
