Totally Endoscopic Robotically Assisted Coronary Artery Bypass Grafting
Totally endoscopic robotically assisted coronary artery bypass grafting is a newer technique in heart surgery.
It’s a minimally invasive method of performing a heart bypass.
During a TECAB grafting procedure, the surgeon deflates your lungs and makes a number of small cuts between your ribs.
Robotic arms, controlled by the surgeon, are used to carry out the surgery.
An endoscope is attached to the robotic arms so the surgeon can see inside your body and view the results of the surgery on a screen.
TECAB grafting can be carried out using a heart-lung bypass machine, or it can be done off-pump.
There are lower rates of wound infection with this type of surgery, plus minimal scarring and a faster recovery time.
But as this is a newer technique that’s only been carried out on a small number of people, it’s difficult to assess how effective and safe it is in the short and long term, and how the outcomes compare with other types of surgery.
If you’re considering having TECAB, it’s important you understand there are still uncertainties about how safe the procedure is and how well it works.
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
Heart Procedures And Surgeries
If you’ve had a heart attack, you may have already had certain procedures to help you survive your heart attack and diagnose your condition. For example, many heart attack patients have undergone thrombolysis, a procedure that involves injecting a clot-dissolving agent to restore blood flow in a coronary artery. This procedure is administered within a few hours of a heart attack. If this treatment isn’t done immediately after a heart attack, many patients will need to undergo coronary angioplasty or coronary artery bypass graft surgery later to improve blood supply to the heart muscle.
See diagnostic tests and procedures to better understand the tests you may have to undergo to find out if you had a heart attack, how much damage was done and what degree of coronary artery disease you have.

What Are The Types Of Coronary Artery Bypass Graft Surgery
There are several types of CABG surgery:
Coronary Artery Bypass Grafting
Coronary artery bypass grafting is a type of surgery that improves blood flow to the heart. It’s used for people who have severe coronary heart disease , also called coronary artery disease.
CHD is a condition in which a substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
Plaque can narrow or block the coronary arteries and reduce blood flow to the heart muscle. If the blockage is severe, angina , shortness of breath, and, in some cases, heart attack can occur.
CABG is one treatment for CHD. During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery.
This creates a new passage, and oxygen-rich blood is routed around the blockage to the heart muscle.

What Conditions Are Treated By This Surgery
The condition thats most likely to lead to CABG is coronary heart disease, a group of conditions that includes heart attack and coronary artery disease. Other conditions under coronary heart disease include angina pectoris, which is chest pain caused by ischemia in your heart, and silent myocardial ischemia, which is heart ischemia without any symptoms.
Conditions that fall under coronary heart disease usually involve a narrowing of the arteries in your heart because of a buildup of a fatty, wax-like residue called plaque. As plaque builds up on the inside of your heart’s arteries, the arteries become stiffer and narrower. If an area of plaque breaks open, blood clots can form there and create blockages in those arteries. Those blockages cause ischemia in parts of your heart, which can lead to a heart attack.
Procedure Completion Both Methods
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 Is This Procedure
Coronary artery bypass grafting is a surgery that restores blood flow to areas of your heart that arent getting enough blood. This surgery can improve your heart function and how you feel, especially when youve just had a heart attack or theres an increased risk for you to have one in the near future.
How To Prepare For Open
Tell your doctor about any drugs you are taking, even over-the-counter medications, vitamins, and herbs. Inform them of any illnesses you have, including herpes outbreak, cold, flu, or fever.
In the two weeks before the surgery, your doctor may ask you to quit smoking and stop taking blood-thinning medications, such as aspirin, ibuprofen, or naproxen.
Its important to talk to your doctor about your alcohol consumption before you prepare for the surgery. If you typically have three or more drinks a day and stop right before you go into surgery, you may go into alcohol withdrawal. This may cause life-threatening complications after open-heart surgery, including seizures or tremors. Your doctor can help you with alcohol withdrawal to reduce the likelihood of these complications.
The day before the surgery, you may be asked to wash yourself with a special soap. This soap is used to kill bacteria on your skin and will lessen the chance of an infection after surgery. You may also be asked not to eat or drink anything after midnight.
Your healthcare provider will give you more detailed instructions when you arrive at the hospital for surgery.

Why Do I Need Heart Bypass Surgery
Bypass surgery treats symptoms of coronary artery disease. That happens when a waxy substance called plaque builds up inside the arteries in your heart and blocks blood and oxygen from reaching it.
Your doctor may suggest heart bypass surgery if:
- You have severe chest pain that your doctor thinks happens because several of the arteries that supply blood to your heart are blocked.
- At least one of your coronary arteries has disease that’s causing your left ventricle — the chamber that does most of your heart’s blood pumping — to not work as well as it should.
- There’s a blockage in your left main coronary artery, which gives your left ventricle most of its blood.
- You’ve had other procedures, and either they haven’t worked or your artery is narrow again.
- You have new blockages.
Coronary artery disease can lead to a heart attack. It can cause a blood clot to form and cut off blood flow. Bypass surgery can give your ticker a big health boost.
Coronary Artery Bypass Grafting / Heart Bypass Surgery
CABG surgery has been performed since the 1950s. It really took off following the introduction of a mechanical heart-lung machine in 1953. This machine revolutionised cardiac surgery, allowing the heart to be stopped during surgical manipulation, whilst the heart-lung machine continued to do all the work of the heart. Today CABG surgery is often still performed using this traditional method. More recently however CABG surgery has been performed on a beating heart without the need for bypass!
CABG surgery involves using a vessel from your leg, wrist or inner chest to attach to the coronary vessels on the outside of your heart. Much like a detour on the road, this allows blood to get to the remainder of the heart muscle by bypassing the blockage. Usually an incision is made down the centre of the chest and an open operation performed. Minimal invasion techniques using scopes and other devices are also available.
In general, CABG surgery is quite safe and most patients make a reasonable recovery. Like all operations there are risks including bleeding, infection, pain and more serious consequences such as stroke, heart attack or even death. However CABG surgery is frequently life saving if you have severe disease of the coronary vessels. Medical treatments and angioplasty are alternative therapies but only suitable for some patients.

You might also experience nightmares for a bit after surgery, but it will pass. If you continue to experience them, speak to your doctor and seek help if you feel like you are experiencing PTSD.
How Long Does A Patient Stay In The Hospital After Open
Open-heart surgeries usually necessitate a four to five-day stay in the hospital. The healing process of your breastbone and chest muscles will typically take six to eight weeks once you have been released from the hospital, and you will be able to resume a normal daily routine after that.
Depending on the type of open-heart surgery youve had, you could spend up to a week in the hospital. A tube in your throat will most likely be connected to a ventilator to allow you to breathe. Air and fluid are removed from your chest through tubes . It is possible to drain urine from your bladder using a catheter . In addition to being pale, you will have a puffy appearance on your face and body. You may need the assistance of a nurse if you have a communication problem. There are always lights on and there can be loud noises in an intensive care unit.
If you breathe or move, you may occasionally feel or hear a clicking sound in your chest. When your breathing tube is removed, fluid will enter your lungs. You can learn the fundamentals of deep breathing and coughing with the assistance of a respiratory therapist or nurse. Plunging or secretions in your throat, particularly if you smoke, could indicate a problem. If you are feeling dizzy or unable to breathe, you should contact a nurse. When you eat, its a sign that youve lost your sense of taste. This is normal and should go away in a matter of days or weeks.

Coronary Artery Bypass Graft Surgery
To sew the grafts onto the very small coronary arteries, your doctor will need to stop your heart temporarily. Tubes will be put into the heart so that your blood can be pumped through your body by a heart-lung bypass machine.
Once the blood has been diverted into the bypass machine for pumping, your doctor will stop the heart by injecting it with a cold solution.
When the heart has been stopped, the doctor will do the bypass graft procedure by sewing one end of a section of vein over a tiny opening made in the aorta, and the other end over a tiny opening made in the coronary artery just below the blockage. If your doctor uses the internal mammary artery inside your chest as a bypass graft, the lower end of the artery will be cut from inside the chest and sewn over an opening made in the coronary artery below the blockage.
You may need more than one bypass graft done, depending on how many blockages you have and where they are located. After all the grafts have been completed, the doctor will closely check them as blood runs through them to make sure they are working.
Once the bypass grafts have been checked, the doctor will let the blood circulating through the bypass machine back into your heart and he or she will remove the tubes to the machine. Your heart may restart on its own, or a mild electric shock may be used to restart it.
What Happens After Heart Bypass Surgery
Youâll wake up in an intensive care unit . The breathing tube will still be in your mouth. You wonât be able to talk, and you’ll feel uncomfortable. Nurses will be there to help you. Theyâll remove the tube after a few hours, when you can breathe on your own.
During the procedure, the medical team will probably have put a thin tube called a catheter into your bladder to collect urine. When youâre able to get up and use the bathroom on your own, theyâll remove it.
They also attached an IV line before the surgery to give you fluids and medications. Youâll get it removed once youâre able to eat and drink on your own and no longer need IV medications.
Fluids will build up around your heart after the procedure, so your doctor will put tubes into your chest. Theyâll be there for 1 to 3 days after surgery to allow the fluid to drain.
You may feel soreness in your chest. Youâll have the most discomfort in the first 2 to 3 days after the procedure. You will probably get pain medicines for that.
Youâll also be hooked up to machines that monitor your vital signs — like your heart rate and blood pressure — around the clock.
You should be able to start walking 1 to 2 days after surgery. Youâll stay in the ICU for a few days before you’re moved to a hospital room. Youâll stay there for 3 to 5 days before you go home.

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 Happens During Bypass Surgery
A blood vessel is grafted between the aorta and the coronary artery, or arteries leading to the heart muscle. This allows the blood to bypass blocked arteries and restores blood flow to the heart muscle. It is quite normal to need two to four grafts, otherwise known as a double, triple or quadruple bypass.
Your surgeon will then make a cut, about 25cm long, down the middle of your breastbone and will open your ribcage to reach your heart. Your surgeon may attach the new grafts while your heart is still beating, but it’s more common to temporarily stop your heart.
Your blood is then diverted to a heart-lung machine. This takes over from your heart and lungs to add oxygen to your blood and maintain your circulation.
The grafts will be attached and your heart will be restarted. Your sternum will be rejoined using wires and the skin on your chest will be closed with dissolvable stitches.
The procedure itself takes around three hours, but may take longer depending on how many grafts need to be done. If blood vessels from your leg or arm are being used for grafts, your surgeon will remove and prepare these first.
After your operation, you will be taken to the intensive care unit and will be closely monitored for about 24 hours before you go back to your ward. When you wake up you will be connected to machines that record the activity of your heart, lungs and other body systems. These might include a ventilator machine to help you breathe.

How Long Does Heart Bypass Surgery Recovery Usually Take
After CABG, most people stay in the hospital for 5 to 7 days. While youre there, you can expect the following:
You will probably be on a ventilator, or breathing machine. In most cases, the ventilator can be removed after a few hours.
You will also have little patches with wires attached to your chest that allow your medical team to monitor your heart rate and rhythm.
You will have tubes coming out of your chest, which drain fluid and help your lungs recover.
You will have several other smaller tubes that go into your blood vessels. Medications are given through intravenous catheters. Others are used to monitor your blood pressure and heart function.
The surgeon has to cut through the breastbone, or sternum, to get to your heart. So, you will have a bandage or dressing down the center of your chest to keep that area clean and protected.
Over the next few days, as you recover, those tubes will gradually be removed. And even while you have those tubes in place, your care team, including nurses and therapists, will get you out of bed as soon as it is safe. Moving around helps your breathing, blood flow, and strength. Although this sounds uncomfortable, medication will help to ease the process.
When you leave the hospital, you will likely go home. But if you are very weak or need extra help, you may go to a rehabilitation hospital for a few weeks. There you can rebuild your strength and make sure youre ready to resume daily activities.
