LVADs

A Left Ventricular Assist Device, commonly known as an LVAD, is a mechanical pump that helps a weakened left ventricle in the heart to pump blood. The left ventricle is the main pumping chamber of the heart, responsible for sending oxygenated blood to the rest of the body. When it is unable to perform this function adequately due to conditions like heart failure, an LVAD can be surgically implanted.

LVADs are typically used in two main scenarios: as a bridge to transplant or as destination therapy. A bridge to transplant means the LVAD is a temporary solution to keep a patient alive and stable while they await a donor heart for transplantation. Destination therapy refers to the use of an LVAD as a long-term treatment option for individuals who are not candidates for a heart transplant, providing them with improved quality of life and extended survival.

The device consists of several components, including a pump implanted within the body, a driveline that exits the skin to connect to an external battery-powered controller and power source, and an internal power system. The pump draws blood from the left ventricle and pumps it into the aorta, the body's largest artery. While LVADs can significantly improve symptoms of heart failure, such as shortness of breath and fatigue, they do come with risks, including infection, bleeding, and stroke. Regular monitoring and maintenance are crucial for patients with an LVAD.
