An Overview of the Instruments and Grafts Used for Open Heart Surgery
Every procedure requires special instruments and components.
Two important parts of
open heart surgery include the heart-lung bypass machine and the bypass graft.
Heart-Lung Bypass Machine
It is almost impossible to do open heart surgery without interrupting the natural functions of your heart and lungs. Therefore, a specialized and highly sophisticated machine, called the cardiopulmonary bypass machine, or "heart-lung" bypass machine, was developed to replace the functions of your heart and lungs while your heart surgery is being performed. Similar to your lungs, it will add oxygen to your blood. Like your heart, it will pump the blood to your body. This machine will only be used during your open heart surgery.
Bypass Graft
Heart surgery requires blocked vessels to be bypassed by new vessels. These new vessels, also called grafts, bring blood directly from your aorta to an area of your coronary artery that is just beyond the narrowed or blocked section. This blood vessel may come from an area in your leg, arms, wrist, or chest.
