Bypass surgery involves creating a detour around a blocked artery, usually a coronary artery that supplies blood to the heart (coronary artery bypass surgery) but may be done in other areas (peripheral bypass). Bypass may be minimally invasive or open heart surgery. It may also use a heart lung machine or with endoscopic vein harvesting.
Off-pump coronary artery bypass surgery (OPCAB) is an operation that treats blocked coronary arteries. By dramatically improving the flow of oxygen-rich blood to the heart (a process called revascularization), an off-pump bypass greatly reduces the risk of angina and heart attack.
Off-pump bypass involves the same two procedures that are performed during traditional bypass surgery. In the first, the surgeon removes (harvests) one of the patient’s blood vessels – usually the saphenous vein in the leg or the mammary artery. In the second procedure, the surgeon uses the blood vessel to create a detour (bypass graft) around the blockages in the coronary arteries.
Like conventional bypass surgery, off-pump coronary artery bypass surgery (OPCAB) is an operation that treats patients with blocked coronary arteries. The coronary arteries lie on the surface of the heart and supply the heart muscle with oxygen-rich blood. They may become clogged with deposits of plaque, thus reducing the amount of oxygen-rich blood that can flow to the heart. By dramatically improving the flow of oxygen-rich blood to the heart (a process called revascularization), an off-pump bypass greatly reduces the risk of angina and heart attack.
