The HVAD pump is surgically implanted around the pericardial space, a sac that surrounds the heart. The HVAD connects to the bottom of the left ventricle, drawing oxygen-rich blood through the pump and into the aorta, a large blood vessel that allows blood to flow throughout the body.nnThe HVAD pump is for patients at risk for end-stage left ventricular heart failure, for those who need heart tissue recovery, or it is used as destination therapy. It is essential to understand that a person could already have heart failure but not know it. Having heart failure does not necessarily mean that the heart has completely shut down, it might be that the heart is weak and in the process of failing.
