When Stents Are Best
When the LAD isn’t involved, stents are usually the first choice.
“If you’re talking about blockages in one or even two vessels, the talk with the patient is not so much about bypass versus stenting as about stenting versus medical therapy,” Cutlip says. Medical therapy here means medication and follow-up visits with your cardiologist, but no invasive interventions such as bypass or angioplasty.
There’s another time stents are the best choice: when bypass no longer is an option.
While LAD repair with a mammary artery usually lasts for the rest of a person’s life, CABG grafts in the other two arteries do not. These procedures typically use veins rather than arteries, and in half of people, these repurposed veins start to fail after eight to 10 years.
“Once that happens and you need more work, a second bypass can be done, but generally we prefer to use stents,” says Dr. Cutlip.
CABG best for patients with diabetes, other factors
For people with diabetes, there are fewer questions regarding the choice between bypass surgery and stents. Bypass surgery is generally superior to angioplasty.
When more than one heart artery is blocked, CABG may also offer better survival rates for people with heart failure.
What Happens During Open
Heart surgery is complex. Some surgeries may take six hours or longer. You will receive anesthesia and be asleep during the procedure.
Surgery steps vary depending on the heart condition and procedure. In general, your surgeon:
- Makes a 6- to 8-inch long incision down the middle of your chest.
- Cuts the breastbone and spreads your ribcage apart to reach your heart.
- Connects the heart to a heart-lung bypass machine, if youll have an on-pump surgery. An anesthesiologist gives IV medication to stop your heart from beating and monitors you during the surgery.
- Repairs your heart.
- Restores blood flow to your heart. Usually, your heart starts beating on its own. Sometimes, the heart needs a mild electrical shock to restart it.
- Disconnects the heart-lung bypass machine.
- Closes the breastbone or other incision with wires or sutures that remain in your body.
- Uses stitches to close the skin incision.
Coronary Artery Bypass Grafting
Coronary artery bypass grafting is the most common type of heart surgery performed. The surgeon takes a healthy artery or vein from elsewhere in your body and connects it to supply blood past the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery, creating a new path for blood to flow to the heart muscle.

Difference Between Bypass Surgery And Open Heart Surgery
Key Difference: A bypass surgery is used for treatment of the narrowed arteries. A detour or a bypass is created around the section of a blocked artery. This new pathway is created by using a graft. Open heart surgery refers to a type of surgery in which the chest wall is surgically opened and heart is exposed. This surgery is performed on the muscles, valves, or arteries of the heart. The function of the heart during this surgery is conducted by a heart-lung machine.
A bypass surgery is used for treatment of narrowed arteries. A detour or a bypass is created around the section of a blocked artery. This new pathway is created by using a graft. A graft used in the process can be either natural or artificial. A natural graft consists of a portion of the vein, whereas an artificial graft can be a man made synthetic tube that works as a vein. The surgery is most often performed on the following arteries – coronary arteries of the heart, femoral arteries in the groin or popliteal arteries behind the knee. The graft is attached to the above and below section of an obstructed artery. Blood starts streaming though the new graft vessel and starts providing the essential oxygen and nutrients. A detour or bypass for the flow of blood in the arteries is made in this process, therefore the process is termed as a bypass surgery.
Comparison between Bypass Surgery and Open Heart Surgery:
Difference Between Open Heart Surgery And Closed Heart Surgery
Key Difference: Open heart surgery deals with the structures inside the heart, whereas close heart surgery deals with the structures outside the heart. Unlike an open heart surgery, a heart-lung machine is not required in a closed heart surgery.
Open heart surgery refers to a type of surgery that involves repairing or fixing structures that are located insider the heart. In this type of surgery chest wall is surgically opened and heart is exposed. This surgery is performed on the muscles, valves, or arteries of the heart. The function of the heart during this surgery is conducted by a heart-lung machine. During this surgery, heart beats are temporarily stopped and the demand of oxygen is fulfilled by the heart-lung machine. Special tubes called cannular are placed in the veins as well as in the arteries of the heart. A variant of open heart surgery is known as the beating heart surgery. In this type of surgery, the heart is not stopped from beating.
Closed heart surgery refers to the type of surgery in which heart lung machine or bypass machine is not used. The surgeons work on the structures located in the exterior area of the heart. The heart continues its functions during the surgery. Various surgical operations are done on the basis of this method like surgery for aoratic contraction, BT interventions and ligation of patent Botallus duct. In this kind of heart surgery chest cavity remains closed and just small incisions are made.

Sawing Open The Breastbone
Heart bypass surgery is an open-heart surgery and the heart needs to be exposed. In the case of bypass surgery this is done by sawing through the breastbone in a technique known as median sternotomy. A specially designed electric saw is used for this. A median sternotomy is demonstrated in the next image. Once the bone is cut, small bleeders are cauterized to stop the bleeding.

Whats Recovery Like After Bypass Surgery
Itâs a gradual process. You may feel worse right after surgery than you did before. You might not be hungry and even be constipated for a few weeks after the surgery. You could have trouble sleeping while youâre in the hospital. If the surgeon takes out a piece of healthy vein from your leg, you may have some swelling there. This is normal.
Your body needs time to recover, but youâll feel better each day. It’ll take about 2 months for your body to feel better after surgery.
Youâll visit your doctor several times during the first few months to track your progress. Call them if your symptoms donât improve or youâre feeling worse.
Talk with your doctor about the best time to return to your normal day-to-day activities. What’s right for you will depend on a few things, including:
- Your overall health
- How many bypasses you’ve had
- Which types of activity you try
You’ll need to ease back in. Some common plans include:
Driving. Usually 4 to 6 weeks, but you need to make sure your concentration is back before you get behind the wheel.
Housework. Take it slow. Start with the simple things you like to do and have your family help with the heavy stuff for a bit while you recover.
Sex. In most cases, you should be physically good to go in about 3 weeks. But you may lose interest in sex for a while after your surgery, so it could be as long as 3 months before you’re ready to be intimate again.

What Is The Recovery Time
Recovery time depends on the type of surgery you have, but for most types of heart surgery you are likely to spend a day or more in the hospitalâs intensive care unit. Then you will be moved to another part of the hospital for several days until you go home.
The National Heart, Lung, and Blood Institute notes that the length of your recovery time at home will depend on the type of surgery you had, your overall health before the surgery, and whether you experienced any complications from surgery. For example, full recovery from a traditional coronary artery bypass may take six to 12 weeks or more.
Physician anesthesiologists are the most highly skilled medical experts in anesthesia care, pain management, and critical care medicine. They have the education and training that, in some circumstances, can mean the difference between life and death.
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.
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.

Testing A Diagnostic Tool
As many as 40% of Americans older than 60 experience some narrowing of their coronary arteries caused by the buildup up of plaque in the walls of the blood vessels, according to the American Heart Association. Most cases arent serious enough to limit oxygen supply to the heart and can be treated with statins or aspirin. But significant blockages can cause chest pain and increase the risk of heart attack or death.
For years, clinicians relied exclusively on angiograms an X-ray of the coronary arteries to determine whether the vessels were sufficiently narrowed to warrant intervention. But angiograms can be misleading, showing a tight space within a vessel when none exists, Fearon said.
A better diagnostic tool, known as fractional flow reserve, or FFR, can measure whether blood flow has been reduced to a dangerous level. Doctors thread a wire with a small sensor on the tip into the artery to measure the pressure of the flow. In a significantly narrowed vessel, the blood pressure will drop in that segment of the vessel beyond the narrowing, signaling the need for intervention.
In the FAME 1 study, whose results were published in 2009, Fearon and his colleague found that use of FFR led to fewer stent placements and fewer complications when compared with stenting based on angiogram images alone. Among patients with FFR-guided stents, the rates of death, heart attack and the need for repeat procedures were significantly less, they found.
What Are The Risks Of Heart Bypass Surgery
All surgeries come with the chance of problems. Some include:
- Blood clots that can raise your chances of a stroke, a heart attack, or lung problems
- Problems breathing
Many things affect these risks, including your age, how many bypasses you get, and any other medical conditions you may have. You and your surgeon will discuss these before your operation.
Once youâve recovered, your symptoms of angina will be gone or much better. Youâll be able to be more active, and youâll have a lower risk of getting a heart attack. Best of all, the surgery can add years to your life.
Tavr Once Was Available Only For The Sickest Aortic Stenosis Patients But The Minimally Invasive Procedure Is Now More Often An Alternative To Open Heart Surgery
The minimally invasive transcatheter aortic valve replacement procedure once thought appropriate only for the sickest aortic stenosis patients increasingly is being used as an alternative to open heart surgery valve replacement.
TAVR is an option now for nearly all patients.
With TAVR, were able to place the new valve by entering through an artery, much like we would a stent, said D. Sean Stewart, M.D., interventional cardiologist with Norton Heart & Vascular Institute. Patients eligible for this minimally invasive approach often go home after an overnight stay.
TAVR is now an option even for patients for whom open heart surgery for valve replacement would be low risk. The procedure was at first only for those who faced high risk if they underwent open heart surgery, then expanded to include those with intermediate risk.
Open heart surgery is still preferred for younger patients, those with congenitally malformed valves and other specific cases.
Aortic stenosis means the valves have narrowed, become calcified and rigid. One in 2 patients with untreated symptoms of severe aortic stenosis will die within an average of two years.
What Should I Expect Coming Home From Open Heart Surgery
Every person and every procedure has a different healing process. After surgery, your doctor will teach you how to care for your incisions, what to watch out for, and how to understand the difference between abnormalities and post-surgery symptoms.
Typical symptoms you may have after your surgery are:
- Muscle pain
Procedure Of Bypass Surgery
Surgeons use heart bypass surgery to operate the patients if other less invasive procedures and medications do not work. In heart bypass surgery, a blood artery from the chest, arms, or legs is removed and used to form a diversion or bypass around the blockage. This permits blood to return to the heart.
Surgeons can operate on many arteries at the same time. A double bypass involves two repairs, a triple bypass involves three, and a quadruple bypass involves four repairs. The quintuple bypass is the most complicated cardiac bypass surgery as it involves bypassing all five of the hearts main arteries.

Under What Conditions Do You Need The Surgery
- A blockage in the left main coronary artery prevents the blood from passing into the left ventricle.
- You are suffering from severe chest pain due to a blockage in several arteries that supply blood.
- You have gone through a procedure before, but it hasnt worked, or your artery has narrowed down again.
- A disease has developed inside your coronary arteries, compromising the left ventricles work, which is the main chamber that does all of the hearts blood pumping.
Coronary artery disease is the leading cause of a heart attack. This disease can cause the blood to clot and block the blood flow. However, if you go through bypass surgery, it can boost your health again.

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.
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.
When Is Bypass Surgery Needed
The three coronary arteries of the heart are not all created equal. The left anterior descending artery is the most significant artery. For a blocked LAD, bypass surgery is typically the best option. Even if both of the other arteries are blocked, and LAD is not obstructed and there are no other complicating issues, stents are more likely to be used.
Also, LAD bypass uses the mammary artery for the graft, which is positioned in the chest near the heart. CABG utilising the mammary artery continues for decades as the risk of complications are very low. Furthermore, the mammary artery is almost immune to blockage.
Lastly, bypass surgery is also generally the best choice in factors such as diabetes.

Difference Between Open Heart Surgery And Heart Bypass Surgery
Heart bypass surgery is a type of open-heart surgery in which the doctors open up the chest through a minor cut to reach the heart. After making incisions, the doctors can perform the rest of the surgery in two forms: on-pump or off-pump.
In on-pump surgery, the surgeons use a heart-lung machine to stop your heart and perform the operation efficiently. The device will circulate the blood and help your body to breathe.
Whereas, in off-pump surgery, your heart beats throughout the process also called beating heart surgery. The process does not require a heart-lung machine.
But sometimes, the doctor can perform surgery without cutting the chest, which is known as closed heart surgery. The risk and side effects of these procedures depend on person-to-person. So its best to let the doctor decide which treatment will be best for you.
