Coronary Bypass Surgery
A coronary bypass is needed when an artery in the heart
is narrowed or blocked due to coronary artery disease. An
artery or vein from another part of the body is grafted to
the heart to bypass the narrowed area. To accomplish this
the heart must be stopped. A heart-lung machine diverts the
blood during the operation and subsequently re-pumps the blood
back into the body.
Coronary bypass surgery is often used when the patient has
several blockages and is not considered a candidate for angioplasty.
Coronary artery bypass is one of the most common cardiac surgical
procedures.
