heart Heart failure is a major chronic condition in the United States, marked by increasing prevalence, hospitalizations, and deaths.

One type, called left-sided failure, is caused by a progressive failure of the left ventricle—the large, muscular chamber of the heart that pumps oxygen-rich blood out of the heart to the rest of the body. This form heart failure is often treated with medications and/or surgery. One surgical treatment, aheart transplant, can take years of waiting for a donor.

Patients now have another option called a left ventricular assist device (LVAD). The LVAD is a device that takes over the work of the left ventricle, which may eliminate the need for a transplant. Here is some information on this technology.
