Question

A total artificial heart (TAH) is an electrically powered pump that circulates blood into the pulmonary artery and the aorta, thus replacing the functions of both the right and left ventricles. What makes it different from a left ventricular assist device (LVAD)?

1) An LVAD only supports a failing left ventricle.
2) It never needs batteries.
3) It is specifically designed for long-term use.
4) It is designed for extremely active patients.

Answer 1

A total artificial heart (TAH) is designed to replace the functions of both the right and left ventricles, while a left ventricular assist device (LVAD) only supports a failing left ventricle. TAH is specifically designed for long-term use and is not limited to extremely active patients.

Step-by-step explanation:

A total artificial heart (TAH) is an electrically powered pump that replaces the functions of both the right and left ventricles. It circulates blood into the pulmonary artery and the aorta. On the other hand, a left ventricular assist device (LVAD) only supports a failing left ventricle. It is specifically designed for long-term use and is not limited to extremely active patients.
