What is the primary purpose of an LVAD?

The primary purpose of a Left Ventricular Assist Device (LVAD) is to assist in pumping blood in patients with advanced heart failure. An LVAD is a mechanical pump that is implanted in individuals whose hearts are unable to pump sufficient blood to meet the body's needs. This device takes over the pumping function of the left ventricle, helping to maintain systemic circulation and alleviate symptoms of heart failure.

LVADs are particularly beneficial for patients who are awaiting heart transplantation or for those who are not candidates for surgery. They do not cure heart disease, as they are not designed to repair or replace the damaged heart tissue, but rather to provide support to the failing heart. Moreover, they do not primarily restore normal heart rhythm nor completely eliminate the need for medications, as patients often still require pharmacological management for heart failure and to prevent complications related to the LVAD itself. Thus, option B accurately reflects the essential role of an LVAD in managing advanced heart failure.
