World Class, State-of-the-Art Coronary Artery Bypass Graft w/Lower Costs Coronary Artery Bypass Graft (CABG) Surgery Coronary artery bypass graft (CABG) surgery is performed about 350,000 times annually in the United States, making it one of the most commonly performed major operations. CABG surgery is advised for selected groups of patients with significant narrowings and blockages of the heart arteries (coronary artery disease). CABG surgery creates new routes around narrowed and blocked arteries, allowing sufficient blood flow to deliver oxygen and nutrients to the heart muscles. Coronary Artery Bypass Graft (CABG) Total Price $6,900
How does coronary artery disease develop? The atherosclerotic process causes significant narrowing in one or more coronary arteries. When coronary arteries narrow more than 50 to 70%, the blood supply beyond the plaque becomes inadequate to meet the increased oxygen demand during exercise. The heart muscle in the territory of these arteries becomes starved of oxygen (ischemic). Patients often experience chest pain (angina) when the blood oxygen supply cannot keep up with demand. Up to 25% of patients experience no chest pain at all despite documented lack of adequate blood and oxygen supply. These patients have "silent" angina, and have the same risk of heart attack as those with angina. When a blood clot (thrombus) forms on top of this plaque, the artery becomes completely blocked causing a heart attack. ![]() When arteries are narrowed in excess of 90 to 99%, patients often have accelerated angina or angina at rest (unstable angina). Unstable angina can also occur due to intermittent blockage of an artery by a thrombus which is dissolved by the body's own protective clot dissolving system. Bypass Surgery, Coronary Artery What is coronary artery bypass surgery? This is a type of heart surgery. It's sometimes called CABG ("cabbage"). The surgery reroutes, or "bypasses," blood around clogged arteries to improve blood flow and oxygen to the heart. Why is this surgery done? The arteries that bring blood to the heart muscle (coronary arteries) can become clogged by plaque (a buildup of fat, cholesterol and other substances). This can slow or stop blood flow through the heart's blood vessels, leading to chest pain or a heart attack. Increasing blood flow to the heart muscle can relieve chest pain and reduce the risk of heart attack. How is coronary bypass done? Surgeons take a segment of a healthy blood vessel from another part of the body and make a detour around the blocked part of the coronary artery.
A patient may undergo one, two, three or more bypass grafts, depending on how many coronary arteries are blocked. Cardiopulmonary bypass with a pump oxygenator (heart-lung machine) is used for most coronary bypass graft operations. This means that besides the surgeon, cardiac anesthesiologist and surgical nurse, a competent perfusionist (blood flow specialist) is required. During the past several years, more surgeons have started performing off-pump coronary artery bypass surgery (OPCAB). In it, the heart continues beating while the bypass graft is sewn in place. In some patients, OPCAB may reduce intraoperative bleeding (and the need for blood transfusion), renal complications and postoperative neurological deficits (problems after surgery). What happens after bypass surgery? After surgery, the patient is moved to a hospital
bed in the cardiac surgical intensive care unit. Heart rate and blood pressure
monitoring devices continuously monitor the patient for 12 to 24 hours. Family
members can visit periodically. Medications that regulate circulation and blood
pressure may be given through the I.V. (intravenously). A breathing tube (endotracheal
tube) will stay in place until the physicians are confident that the patient is
awake and ready to breathe comfortably on his or her own.
Many of these side effects usually disappear in four to six weeks, but a full recovery may take a few months or more. The patient is usually enrolled in a physician-supervised program of cardiac rehabilitation. This program teaches stress management techniques and other important lessons (e.g., about diet and exercise) and helps people re-build their strength and confidence. Patients are often advised to eat less fat and cholesterol walk or do other physical activity to help regain strength. Doctors also often recommend following a home routine of increasing activity -- doing light housework, going out, visiting friends, climbing stairs. The goal is to return to a normal, active lifestyle. Most people with sedentary office jobs can return to work in four to six weeks. Those with physically demanding jobs will have to wait longer. In some cases they may have to find other employment. What about alternatives to coronary artery bypass? The American Heart Association doesn't have a policy on this issue. In some patients, alternative treatment of coronary artery disease includes medical therapy with specific medication or non-surgical treatment such as balloon angioplasty, laser angioplasty, stents or atherectomy (plaque removal). Your physician (cardiologist) will help decide which treatment is best for you.
