Through a large artery called the aorta to supply the body with the oxygen and nutrients it needs in left-sided heart failure the left ventricle is not able to pump enough blood to the body the two types of left-handed heart failure are

Diastolic where the left ventricle can't relax enough to fill with blood and more commonly systolic where the left ventricle can't contract strongly enough to push blood to the body in severe or end-stage heart failure the

Heart is getting weaker and doesn't respond to medication four left-sided end-stage systolic heart failure a doctor may recommend an implantable left ventricular assist device or LVAD to help the heart pump

Enough blood to the body an LVAD is a small mechanical pump implanted inside the chest or abdomen that takes over the job of the weak left ventricle blood flows from the left ventricle through an inflow tube to the pump the pump pushes

The blood through an outflow tube into the aorta from here the blood travels normally from the aorta to the rest of the body a cable called a drive line connects the LVAD pump inside the chest to a control unit located on the outside

Of the body the control unit is a small computer that controls the functions of the pump and alerts the patient if there are any problems the pump and control unit receive power through a cord connected to a battery pack finally the

Control unit and battery pack are held in a light weight patient pack an LVAD maybe a temporary treatment until a heart transplant can be performed or if the patient isn't able to have a heart transplant an LVAD may

Be used for destination therapy which is long-term treatment
