What Happens Before This Procedure
CABG is major surgery, and people who have this done must first undergo a wide range of tests and other preparations.
Imaging and lab tests
Before you can undergo CABG, you will need to undergo several tests to see if it’s safe for you to have this surgery and whether or not you need the surgery in the first place.
The potential tests include, but arent limited to, the following:
- Lab tests, such as a complete blood count, that analyze your cholesterol, blood sugar, and other factors. Other possible tests include urine tests that analyze how well your kidneys function.
Information and education
Part of preparing for CABG involves informing and educating you on what to expect and what you need to do before and after surgery to help you have the best possible outcome. Topics that you’ll learn about include:
Outcomes After Heart Bypass Surgery Better With No
- For coronary artery bypass surgery, the bypass grafts using leg veins were more likely to be successful and stay open if the vein was removed along with some protective surrounding tissue, according to a large study in China.
- People who received coronary artery bypass using the modified technique were less likely to have a recurrence of heart-related chest pain.

DALLAS, Sept. 13, 2021 When a modified surgical technique was used to gently remove sections of leg veins used in coronary artery bypass surgery, the grafts were less likely to become blocked and fewer people had a recurrence of heart-related chest pain, according to new research published today in the American Heart Associations flagship journal Circulation.
Coronary artery bypass grafting is a surgical procedure that uses blood vessels taken from another part of the body to create a path for blood flow around blocked or narrowed coronary arteries, thus allowing more blood and oxygen to reach the heart muscle. The saphenous vein that runs along the inner thigh is one of the most common blood vessels used in CABG. Within a year after surgery, the vein segments can become blocked – about 15% of the time, which can lead to the recurrence of chest pain.
In the first year after coronary artery bypass surgery, the researchers found:

What Happens During Heart Bypass Surgery
Youâll be asleep the whole time. Most operations take between 3 and 6 hours. A breathing tube goes in your mouth. It’s attached to a ventilator, which will breathe for you during the procedure and right afterward.
A surgeon makes a long cut down the middle of your chest. Then they’ll spread your rib cage open so that they can reach your heart.
Then the surgeon will remove a blood vessel, called a graft, from another part of your body, like your chest, leg, or arm. They’ll attach one end of it to your aorta, a large artery that comes out of your heart. Then, they’ll the other end to an artery below the blockage.
The graft creates a new route for blood to travel to your heart. If you have multiple blockages, your surgeon may do more bypass procedures during the same surgery .
In some cases, the surgeon may not need to stop your heart. These are called âoff-pumpâ procedures. Others need only tiny cuts. These are called âkeyholeâ procedures.
Some surgeries rely on the help of robotic devices. Your surgeon will recommend the best operation for you.

What Is Heart Bypass Surgery
A heart bypass procedure involves attaching a blood vessel taken from elsewhere in the body to the diseased coronary artery. This results in a redirection of the blood flow around the blockage. When a person has a double bypass surgery, it means that two or three arterial blockages are rerouted.
Heart bypass surgery is done as an inpatient procedure. It’s often a planned procedure, but in some instances, an emergency heart bypass procedure is performed after a person has a heart attack.
Heart bypass surgery may sometimes be performed on infants and children, but not for the same reason adults have the procedure done. Rather, infants and children would be more likely to need heart bypass surgery because of congenital heart disease.
The steps involved in a traditional open method of heart bypass surgery include:

Considering Complexity Of Heart Disease
The researchers looked at results based on the patients underlying coronary disease. They found that patients with less complex coronary artery disease did better with stents, as physicians could limit the number of the mesh tubes they had to place.
I think the study results will guide both physicians and patients on the best strategy for their circumstances, Fearon said. If patients have very complex disease that would require numerous stents, then bypass might be a better option. If they have less complex disease, they can feel reassured that by receiving the latest generation of drug-eluting stents guided by FFR, their outcomes would be just as good as they would be with surgery.
He said stents also have an advantage in that they entail shorter hospital stays and faster recoveries. Patients who receive stents generally go home the same day and recover quickly. Bypass patients, on the other hand, may remain in the hospital for as many as five days or longer, with a recovery time of six to eight weeks. In the study, bypass patients also had a higher incidence of major bleeding, arrythmia, acute kidney injury and rehospitalization within 30 days.
The FAME 3 trial was initiated by Fearon and two of the other investigators and was sponsored by Stanford Medicine. Medtronic Inc. and Abbott Vascular Inc. provided research grants for the study but were not involved in its design or implementation.

How Long Will I Have To Wait For Surgery
The length of time youll have to wait to have a coronary artery bypass graft will vary from area to area.
Your GP or cardiac surgeon should be able to tell you what the waiting lists are like in your area or at the hospital you have chosen.
Ideally, you should be treated within 3 months of the decision to operate.

Your doctor will sew the sternum together with small wires .
He or she will insert tubes into your chest to drain blood and other fluids from around the heart.
Your doctor will sew the skin over the sternum back together.
Your doctor will put a tube through your mouth or nose into your stomach to drain stomach fluids.
He or she will then apply a sterile bandage or dressing.
What Happens During Coronary Artery Bypass
Coronary artery bypass graft surgery requires a stay in a hospital. Procedure may vary depending on your condition and your doctor’s practices.
Generally, CABG follows this process:
You will be asked to remove any jewelry or other objects that may interfere with the procedure.
You will change into a hospital gown and empty your bladder.
You will lie on your back on an operating table.
The anesthesiologist will continuously monitor your heart rate, blood pressure, breathing, and blood oxygen level during the surgery. Once you are sedated , a breathing tube will be put into your throat and you will be connected to a ventilator, which will breathe for you during the surgery.
A healthcare professional will insert an intravenous line in your arm or hand. Other catheters will be put in your neck and wrist to monitor your heart and blood pressure, as well as to take blood samples.
A catheter will be put into your bladder to drain urine.
The skin over the surgical site will be cleaned with an antiseptic solution.
Once all the tubes and monitors are in place, your doctor will make incisions in one or both of your legs or one of your wrists to access the blood vessel to be used for the grafts. He or she will remove the vessel and close those incision.
The doctor will make an incision below the Adam’s apple to just above the navel.
The doctor will cut the sternum in half lengthwise. He or she will separate the halves of the breastbone and spread them apart to expose your heart.

How Do You Prepare For Bypass Surgery
Before your surgery, youâll get blood tests, chest X-rays, and an electrocardiogram . Your doctor may also do an X-ray procedure called a coronary angiogram. It uses a special dye to show how the blood moves through your arteries.
Your doctor will also let you know if you need to make any changes to your diet or lifestyle before the surgery and make any changes to medicines you take. Also tell your doctor about any vitamins and supplements you take, even if they are natural, in case they could affect your risk of bleeding.
Youâll also need to make plans for recovery after your surgery.
What Is The Recovery Time
Most people who have CABG will need several weeks to fully recover from this procedure. During that time, your provider will likely have you avoiding any strenuous activities or situations that might put too much stress on your heart and incisions.
Your healthcare provider is the best person to tell you how long it will probably take you to recover and what you should expect. Theyll also tell you when you can start resuming your regular activities like work, exercising, driving, etc.

Why Is Coronary Bypass Surgery Done
Your heart works 24/7, supplying your entire body with blood. To do its job, your heart also needs blood flow, which it gets through a network of supply arteries that wrap around it. When tissues in your body arent getting enough blood flow, this causes a problem called ischemia .
The muscle cells in your heart are especially sensitive to ischemia, and when it’s severe, those heart muscle cells will start to die. Coronary artery bypass grafting treats ischemia by restoring blood flow to the affected heart muscle.
What Is Coronary Bypass Graft Surgery
Coronary artery bypass graft surgery is a procedure used to treat coronary artery disease. Coronary artery disease is the narrowing of the coronary arteries the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This build-up narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle.
One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in your body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from your leg or an artery in your chest. An artery from your wrist may also be used. Your doctor attaches one end of the graft above the blockage and the other end below the blockage. Blood bypasses the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery.
Traditionally, to bypass the blocked coronary artery, your doctor makes a large incision in the chest and temporarily stops the heart. To open the chest, your doctor cuts the breastbone in half lengthwise and spreads it apart. Once the heart is exposed, your doctor inserts tubes into the heart so that the blood can be pumped through the body by a heart-lung bypass machine. The bypass machine is necessary to pump blood while the heart is stopped.

So How Long Does Heart Bypass Surgery Last
Lets summarize the article so far. If a patient has a LIMA bypass, it is almost 90% likely to remain open, even 10 years after the operation, and that is just great. For the other blockages where an SVG graft is used, the bypasses are about 50% likely to remain open at 10 years. If grafts go down its not necessarily a disaster, there are often good treatment options.
For Severe Heart Disease Bypass Surgery Slightly Better Than Stenting With Caveats Study Finds
Among heart-disease patients in a study who received stents, the incidence of a major complication death, heart attack, stroke or the need for a repeat procedure was 10.6% after a year. Among bypass patients, the rate was 6.9%.
Patients with severe coronary artery disease generally fared better with bypass surgery than with stents to open blocked arteries, according to a major new multinational study led by Stanford Medicine investigators.
However, some patients benefited more from stents, particularly if their disease wasnt complex, the researchers found.
The good news for patients is that both groups did better than what was found in previous studies, and the differences between the two strategies has lessened, said William Fearon, MD, professor of cardiovascular medicine and principal investigator of the trial. He said the trial, the largest of its kind, will serve as a guide for determining which approach is best for individual patients.
I think it will have an immediate impact on how patients and physicians choose treatment, said Fearon, who is also the director of interventional cardiology at Stanford.
A paper describing the study, called the FAME 3 trial, was published online Nov. 4 in The New England Journal of Medicine. Fearon shares lead authorship on the paper with Frederick Zimmermann, MD, of Catharina Hospital in the Netherlands. Nico Pijls, MD, PhD, of Catharina Hospital, was the papers senior author.

Endoscopic Saphenous Vein Harvesting
Endoscopic saphenous vein harvesting is a less invasive method of removing the veins from your legs.
Rather than making a large cut in your leg, the surgeon makes a number of small ones near your knee. This is known as keyhole surgery.
A special device called an endoscope will be inserted into the cut.
An endoscope is a thin, long flexible tube with a light source and video camera at one end, so that images of the inside of your body can be relayed to an external television monitor.
The endoscope allows the surgeon to locate your saphenous vein. Surgical instruments can also be passed along the endoscope to remove a section of the vein. Nearby tissue is then sterilised with antibiotic fluid and the cut is healed.
The main advantages of this technique are that there’s likely to be a:
- shorter hospital stay
- lower risk of leg wound infections
- quicker recovery from CABG
Purpose Of Heart Bypass Surgery
The primary purpose of heart bypass surgery is to ensure adequate blood flow and oxygenation to the heart muscle, for those who have coronary artery disease, associated with:
- Angina: The primary symptom of coronary artery disease involving chest pain from ischemia .
- Coronary artery stenosis: A condition involving atherosclerotic plaques that are made up of cholesterol deposits. The plaques occlude the passage of normal blood flow in one or more or the arteries that supply oxygen to the heart muscle.
- Myocardial infarction : This results from blocked coronary arteries .

When Should I See My Healthcare Provider
You should see your healthcare provider as recommended after your procedure. They’ll schedule follow-up visits where they can check your heart function, remove any remaining stitches or staples, and make sure your wounds are healing well.
During your recovery, you should also follow your providers guidance regarding the following:

The Heart Bypass Vessel
The most well known bypass is called the LIMA to LAD. LIMA stands for left internal mammary artery and is an artery that runs from the left collarbone area down the chest wall. LAD stands for left anterior descending artery which is the artery commonly responsible for the Widowmaker Blockage. In a bypass it is carefully taken down from the chest wall and attached beyond a blockage acting as a bypass. The LIMA to LAD is very successful as a bypass and has good long-term results. In other types of bypasses, arteries can be taken from the forearm, or veins can be taken from the legs. Read this article on heart blockages and this article on the Widowmaker for more information. This article titled how long does a bypass last is useful and goes in to a little more depth about the different bypasses.
