	Heart bypass surgery
		Heart bypass surgery creates a detour or "bypass" around the blocked part of a coronary artery to restore the blood supply to the heart muscle.
		In the traditional surgery, the patient is connected to the heart-lung machine, or bypass pump, which adds oxygen to the blood and circulates blood to other parts of the body during the surgery.
		Recently, coronary bypass surgery is being performed with the aid of a robot, which allows the surgeon to perform the operation without even being in the same room as the patient.

	Bypass Surgery
		Unlike conventional surgery, which has a 10"-12" incision and places the patient on the heart-lung machine, new minimally invasive approaches may avoid placing the patient on a heart-lung machine, and can be performed through a 3"-5" incision placed between the ribs, or may be done with several small incisions.
		Minimally invasive bypass surgery is believed to have the same beneficial results as conventional bypass surgery--restoring adequate blood flow and normal delivery of oxygen and nutrients to the heart.
		One of the greatest challenges in minimally invasive bypass surgery is the difficulty of suturing or "sewing" on a beating heart.

	Heart bypass surgery - Evanston Northwestern Healthcare (Site not responding. Last check: 2007-10-22)
		Coronary artery bypass grafting (CABG) or heart bypass surgery is recommended when one or more coronary arteries are seriously blocked and blood supply to the heart muscle is insufficient.
		Although the heart itself is not "opened", the heart-lung bypass machine is used to re-route the blood from the heart while the surgery is being done to provide adequate circulation to the brain and other vital organs.
		Coronary bypass surgery is an open heart surgery (the chest is opened, but not the heart itself).

	Coronary artery bypass surgery - MayoClinic.com
		Coronary bypass surgery is one of the most common and effective procedures to manage blockage of blood to the heart muscle.
		Coronary bypass surgery uses a healthy blood vessel harvested from your leg, arm, chest or abdomen and connects it to the other arteries in your heart so that blood is bypassed around the diseased or blocked area.
		Another risk of coronary bypass surgery is that plaques — the fatty deposits that accumulate on the inner walls of coronary arteries and other vessels in atherosclerosis — may break loose from the walls of the aorta when it's clamped shut for the heart-lung machine.

	Heart Surgery
		Heart surgeons use the beating heart surgery for patients who are not good candidates for angioplasty or stent procedures, or who have tried them without success, as well as for those whose health puts them at a risk for an open heart procedure.
		Bypass surgery, whether done on a beating heart or as a traditional open heart procedure, has two parts: using a healthy blood vessel to detour around a damaged or blocked artery in heart, and actual removal of the healthy blood vessel.
		In the past, heart surgery patients reported more post-operation pain from their legs than from their chest, largely because the vein used in surgery traditionally was removed through an incision the length of the entire leg.

	Open Heart Coronary Bypass Surgery
		Bypass surgery is a procedure performed for most types of coronary artery blockages.
		The purpose of bypass surgery is to increase the circulation and nourishment to the heart muscle.
		The arteries or veins are connected from the aorta to the surface of the heart beyond the blockages forming a graft.

	Heart Info - Bypass Surgery: A Patient Guide
		Bypass surgery is a major operation that usually lasts between two and six hours.
		During bypass surgery, the chest bone is separated, and the ribs are spread apart to allow visible and physical access to the heart.
		The current success rate for bypass surgery is 95 to 98 percent, meaning that between 2 and 5 percent of all patients have complications, including death.

	Dr. Koop - Heart Bypass Surgery- Health Encyclopedia and Reference
		More than 20 years ago, bypass graft surgery was introduced as a way of treating coronary artery disease.
		During the operation, your heart will be temporarily stopped, and you will be placed on a heart-lung bypass machine which will oxygenate and warm your blood while the surgeon works on your heart.
		Like CABG, the surgery is done to reroute, or "bypass," blood around coronary arteries clogged by fatty buildups of plaque and improve the supply of blood and oxygen to the heart.

		Coronary bypass surgery can now be performed with the aid of a robot, which allows the surgeon to perform the operation without even being in the same room as the patient.
		Coronary artery bypass surgery is a treatment option for ischemic heart disease (too little blood reaching the heart muscle).
		As with any surgery, the health of the patient prior to surgery is a major consideration in determining risks.

	Heart Bypass Surgery Techniques
		In traditional heart bypass operations, the chest is opened and a blood vessel from the calf or the chest is used to bypass the clogged artery.
		Figures from the American Heart Association show about 100,000 patients a year might not be eligible for heart bypass surgery or balloon angioplasty, because their arteries are too badly clogged.
		But he said it could only be used for a specific type of heart bypass, where an artery is open in the first portion, closed in the middle and still supplying good heart muscle.

		Doing bypass surgery on a beating heart instead of using a heart-lung machine is far more likely to result in clogging of the new arteries within just a few months, a study found.
		Three months after so-called off-pump surgery, 12% of the grafted blood vessels were blocked, compared with 2% in patients whose hearts were stopped while they were hooked up to a heart-lung machine.
		Khan said off-pump surgery has not been done long enough or studied in large enough numbers yet to conclude whether it is better or worse, and it could be a decade before the verdict is in.

	Heart Bypass Surgery - Information from WebMD
		During coronary artery bypass graft surgery (also called CABG, or "cabbage") a blood vessel is removed or redirected from one area of the body and placed around the area or areas of narrowing to "bypass" the blockages and restore blood flow to the heart muscle.
		If you have this type of bypass, you will probably be prescribed a medication called a calcium channel blocker for about six months after surgery to help keep the radial artery open.
		During surgery, the heart-lung bypass machine (called "on-pump" surgery) is used to take over for the heart and lungs, allowing the circulation of blood throughout the rest of the body.

	Heart Bypass Surgery - Off Pump Bypass Surgery - Heart Surgeon
		Off-pump bypass surgery uses a device that immobilizes only the section of the heart with the diseased artery, so the rest of the heart can carry on its work.
		It’s also possible that off-pump bypass may limit the number of blood vessels operated on since it can be harder to get at some parts of the heart with this technique.
		If you’ve been advised to have bypass surgery, the Harvard Heart Letter suggests that you ask your surgeon if one type is better for you than the other and work together to choose one.

	Clinton Awaits Heart Bypass Surgery (washingtonpost.com)
		The heart is then surgically disconnected from the blood circulation system -- oxygen-poor blood is shunted out of the body before it reaches the heart, purified and cooled by a heart-lung machine and then pumped into the arteries that supply the rest of the body and the brain.
		Bypass surgery essentially restores the muscle's blood supply, replacing the clogged arteries with new ones.
		There is a second type of bypass surgery -- beating-heart surgery -- in which the heart is not disconnected from the blood circulation during the operation.
