From the news story:
The LVAD is a mechanical pump that is implanted inside of a person’s chest to help the heart pump blood. Unlike an artificial heart, it doesn’t replace the heart. Rather, it just helps it do its job.
“What the pump does is we surgically implant it into the left ventricle, to the apex of the left ventricle. Then we connect an outflow device to the aorta, and what it does is when you turn it on, it will actually draw blood out of the left ventricle and push it into the aorta, doing the work of the left ventricle,” said Dr. Orazio Amabile, a cardio-thoracic surgeon. “Because the left ventricle is failing, it doesn’t work, it cant eject very well out of the aortic valve and into the body.”
